5 Installation and Troubleshooting Installation Run setup.exe to install the Windows 64-bit version of Lucis Pro 6 into windows 64-bit versions of Photoshop and Photoshop Elements. During the installation process you select a host application. The available host applications are on the left. One by one you select a host application and click to move it to the right. The only potential exception to this is Photoshop CC. If Photoshop CC shows up under available host applications but will not install, please select Other and then navigate to and select the plug-ins folder of Photoshop CC. For most people, installing the Lucis plug-in is straightforward. You just follow the screens. If you do run into any trouble, please look at the detailed troubleshooting instructions below. If the installation quits, then just read and follow the instructions below. If Lucis did install but when you open Photoshop you can t find it, please use Add/Remove programs to uninstall Lucis and then start over. You can double check the installation by using Control Panel/Programs and Features LucisPro will show up in the list if it did successfully install. The other way is Windows Lucis Pro 6 Plug-in User s Guide 5 Microtechnics

6 to run Photoshop and use the Help/About plug-ins and see if LucisPro is there. If it is, it did install and the About box will display the current version, user name and address. Lucis has to match the version of Photoshop it's being installed into. When you download the installer file, this is only for Windows 64-bit Lucis. Photoshop Elements. If you select your version of Photoshop Elements as the host application and the installation is unsuccessful, please try re-installing Lucis and select Other as the host application. This means that you do not select your version of Photoshop Elements. Then navigate to and select the plug-ins folder of Photoshop Elements. With Photoshop Elements it s very important to check whether it is Windows 32-bit or Windows 64-bit software. The old versions of Windows Photoshop Elements are 32-bit. The current LucisPro version is 64-bit only. If you get an installation error like this: Then install the setup.exe file using Run as Administrator. Right click on the setup.exe file and left click on Run as Administrator. Windows Lucis Pro 6 Plug-in User s Guide 6 Microtechnics

7 Updating Photoshop CC If you update Photoshop CC and Lucis Pro 6 disappears, please reinstall Lucis Pro 6. Backup It is important to backup your software and serial number on a storage device that is separate from your computer in case you need to reinstall the software. Your Presets are saved in a file that you should back up (com.lucis.lucispro.xml). Please note that if you uninstall Lucis your preset file remains. Thus, you can reinstall Lucis and still have your presets.

8 Lucis Processing Overview Images often contain hundreds or thousands of contrast levels. Our eyes can only differentiate 32 levels of contrast. Therefore fine contrast variations are only partially recognized as textures our eyes can't resolve. Lucis enhances the image contrast variations that you choose and would like to view. As a first step, Lucis compares each pixel to every other pixel along hundreds of radial lines in two directions to map out contrast variances. That is why Lucis is very computationally intensive and uses a lot of RAM. Then use the Enhance Detail slider and the Smooth Detail slider to select the range of contrast variances you wish to view. Contrast variances within the selected range are enhanced and contrast variances outside the range are diminished. The relative emphasis of contrast information is shifted, but information is not thrown away. Lucis easily and accurately reveals detail that other image-processing methods can t. The Enhance and Smooth Detail sliders are two of the most powerful tools available for enhancing image detail and image information. Typically, it is best to find the optimum Enhance and Smooth Detail slider values before proceeding with using the other Lucis Pro features. For most scientific applications, Windows Lucis Pro 6 Plug-in User s Guide 8 Microtechnics

9 the Enhance Detail slider is the only feature needed because the primary interest is to accurately view image detail. Single Channel mode versus Split Channel mode The Lucis algorithm modifies image intensity information. Grayscale images are processed perfectly. For color images, how the image is processed in terms of color shifts depends on whether you are in Single Channel mode or Split Channel mode. Many times any color shifts are welcome. They are a desired part of the processing. However, the software does have the Assign Original Image Color slider that allows you to diminish or remove any color shifts. You can also diminish color shifts by using the Mix with Original Image slider. If you need details how Lucis handles color, this is described below. In Single Channel mode, Lucis converts the RGB (Red, Green, Blue) information to HSL (Hue Saturation Luminance). Lucis processes the Luminance information, and then combines the new Luminance (L') with the unaltered Hue and Saturation. The HSL' information is converted back to RGB. Therefore, some Windows Lucis Pro 6 Plug-in User s Guide 9 Microtechnics

10 color images will experience color shifts as Lucis extracts the image detail. This typically occurs in patches of the image, such as orange and gray areas in shadows or brighter patches of blue or red. These color shifts are easily corrected using the Assign Original Image Color slider. With Split Channel mode you can select and individually enhance the intensity information in each color channel separately. So dramatic color shifts can result. Split Channel mode only applies to color images. It is disabled for grayscale images. Enhancing image detail using split Channel mode is not numerically accurate unless the intensity information in each channel is a separate data set. Therefore, for scientific and medical applications Split Channel mode is only used for images with data sets in the individual color channels, such as fluorescence microscopy images. In photography and artistic applications, Split Channel mode is very powerful and can be used in a variety of ways. For example, a photograph may have most of the intensity information in one color channel centered on an object that you wish to make more powerful. Slightly enhancing that channel more than the other two will make the object pop off the page. Or you can enhance each channel differently to achieve a variety of color and detail shifts in the image. Another method is Windows Lucis Pro 6 Plug-in User s Guide 10 Microtechnics

11 to drastically shift the intensity levels in each channel, then use the Assign Original Image Color slider to remove the color shifts, leaving you with just the overall intensity shifts. There are many ways to use Lucis Pro in photography and artistic applications. Please visit the Usage Tips web page at to learn more. Getting Started To open Lucis Pro after you have selected your image in Adobe Photoshop: On the Filter menu, click Lucis. Select Lucis Pro 6.0 on the submenu Figure 1: Opening the Lucis Pro user interface (UI) Windows Lucis Pro 6 Plug-in User s Guide 11 Microtechnics

13 Table 1: Single Channel mode Feature Description 1 Enhance Detail slider Move the slider to the left to increasingly reveal image detail/features. The slider value is displayed at the right end of the slider. You may also type in slider values. Slider values must be an odd number and the value of the Enhance Detail slider must be higher than the Smooth Detail slider value. When the image is first opened the Enhance Detail slider value equals the range of intensity values in the image (the highest intensity minus the lowest intensity), rounded to make it odd. For 8-bit images the maximum value is 257 For 16-bit images the maximum value is 65,537 Windows Lucis Pro 6 Plug-in User s Guide 13 Microtechnics

14 Feature Description 2 Smooth Detail slider Move the Smooth Detail slider to the right to increasingly smooth image detail/features. The slider value is displayed at the right end of the slider. You may also type in slider values. Slider values must be an odd number and the value of the Smooth Detail slider must be less than the Enhance Detail slider value. When the image is first opened, the Smooth Detail slider value is always 1. 3 Preview Scan Lines 4 Processing Scan Lines Enter the number of Scan Lines used by the Lucis processing displayed in the Preview Window here.

16 Feature Description 10 Channel List When the Split Channels check box is unchecked, the Lucis Pro UI is in Single Channel mode. Only one color channel is displayed, labeled Single. Windows Lucis Pro 6 Plug-in User s Guide 16 Microtechnics

17 Split Channel mode Windows Lucis Pro 6 Plug-in User s Guide 17 Microtechnics

18 Table 2: Split Channel mode Window Feature 10 Channel List Description By checking the Split Channels box you change from Single Channel mode to Split Channel mode. In Split Channel mode, each color channel can be selected and enhanced separately. Split Channel mode is only enabled for color images. 11 Display Composite Image This control is enabled in Split Channel mode only. When checked, the Preview window displays the full image with all color channels. Otherwise, the Preview window displays only the selected color channel as a grayscale image. Windows Lucis Pro 6 Plug-in User s Guide 18 Microtechnics

19 Window Feature Description 12 Weight This column controls the amount of the channel s data that is included in the processed image, from 0% (channel is disabled) to 100% (channel is fully visible). Using the Enhance Detail and Smooth Detail Sliders Single Channel Mode Using the Enhance Detail Slider When the image is first opened, the Enhance Detail slider value equals the range of intensity values in the image (the highest intensity minus the lowest intensity), rounded to make it odd. The Enhance Detail slider value can be changed in two ways: 1. By moving the slider thumb left or right. 2. By changing the value in the text box to the right of the slider. Enter a new value and press keyboard Enter. Moving the Enhance Detail slider to the left enhances image detail. Windows Lucis Pro 6 Plug-in User s Guide 19 Microtechnics

20 Enhance Detail slider applied Original (unprocessed) image Enhance: 43, Smooth: 1 Using the Smooth Detail Slider When the image is first opened, the Smooth Detail slider value is always 1. The Smooth Detail slider value can be changed in two ways: 3. By moving the slider thumb right or left. 4. By changing the value in the text box to the right of the slider. Enter a new value and press keyboard Enter. Moving the Smooth Detail slider to the right will smooth the image detail. Windows Lucis Pro 6 Plug-in User s Guide 20 Microtechnics

21 Smooth Detail slider applied Original (unprocessed) image Enhance: 249, Smooth: 39 Using Both Sliders By moving the Smooth Detail slider to the right and moving the Enhance Detail slider to the left you are diminishing the smallest image detail and the largest image features. This enhances mid-range contrast patterns in the image. Windows Lucis Pro 6 Plug-in User s Guide 21 Microtechnics

22 Original (unprocessed) image Both sliders applied Optimum Values for Sliders Moving the Enhance Detail slider and observing the changes to the image will help you get familiar with how detail is revealed. This, plus the Assign Original Image Color slider (when processing color images), is all you need to enhance images for most scientific image processing applications. Next, move the Smooth Detail slider and observe how the detail is smoothed. If you are both enhancing and smoothing the image and you think you are close to what you want the slider values can be tied together (see Tie Together, below) to make it easier to adjust the image processing. Windows Lucis Pro 6 Plug-in User s Guide 22 Microtechnics

23 Split Channel Mode Using the Enhance Detail Slider In Split Channel mode you can select each of the color channels and enhance them separately. The Enhance Detail and Smooth Detail sliders will process the intensity information in the selected color channel only. Below is the Single Channel mode image of a fish (8-bits per channel). The Enhance Detail slider value is 187, which means that the range of intensity values in the image is 187 out of a possible 257. This image is underexposed because of the way water disperses light and has reduced red information. Original (unprocessed) image in Single Channel mode Windows Lucis Pro 6 Plug-in User s Guide 23 Microtechnics

24 The image below shows the same image with Split Channel mode selected, no Lucis processing. You can see that the maximum Enhance Detail sliders for the Red, Green, and Blue channels are 207, 167, and 187 respectively. Since these slider values equal the intensity range in each channel, it is clear that the image is underexposed, especially in the Green channel. Whenever an image is opened in Split Channel mode, the intensity values in each channel are stretched to use the entire range of intensity values. So, just by opening the image in Split Channel mode, Lucis has improved the image by enhancing the low-contrast channels. Original (unprocessed) image in Split Channel mode Red Windows Lucis Pro 6 Plug-in User s Guide 24 Microtechnics

25 The image below shows the image after the Red channel is selected, and the Display Composite Image check box is unchecked. This displays just the intensity information in the red channel, as a grayscale image. Then the next image shows the effect of moving the Enhance Detail slider to the left, causing the intensity information in the Red channel to be enhanced. Enhance Detail slider applied Red channel only, unprocessed Enhance: 93, Smooth: 1 The next image (left) shows the effect of selecting the Green channel. The image on the right shows the effect of moving the Enhance Detail slider to the left, causing the intensity information in the Green channel to be enhanced, in this case by the same amount as the Red channel. Windows Lucis Pro 6 Plug-in User s Guide 25 Microtechnics

26 Enhance Detail slider applied Green channel only, unprocessed Enhance: 93, Smooth: 1 Windows Lucis Pro 6 Plug-in User s Guide 26 Microtechnics

27 The image below on the left shows the effect of selecting the Blue channel. The image below on the right shows the effect of moving the Enhance Detail slider to the left, causing the intensity information in the Blue channel to be enhanced, in this case by the same amount as the Red and Green channels. Enhance Detail slider applied Green channel only, unprocessed Enhance: 93, Smooth: 1 Windows Lucis Pro 6 Plug-in User s Guide 27 Microtechnics

28 The image below shows the effect of checking the Display Composite Image box. This displays a preview of the image that would result from processing the image with the slider settings selected for each color channel. Composite image, each channel processed with the Enhance Detail slider Using the Smooth Detail Slider The identical process using the Smooth Detail slider could be used to smooth the intensity information in each channel. In addition to smoothing image detail, this process frequently results in dramatic color shifts. Therefore, this process is primarily used for creating artistic effects. Windows Lucis Pro 6 Plug-in User s Guide 28 Microtechnics

29 Original (unprocessed) image Smooth Detail slider applied Using Both Sliders Using both sliders together can yield interesting results for artistic applications. The image below shows the original image and the image enhanced as follows: Red Channel: Smooth Detail slider = 29, Enhance Detail slider = 45 Green Channel: Smooth Detail slider = 25, Enhance Detail slider = 55 Blue Channel: Smooth Detail slider = 27, Enhance Detail slider = 45 Windows Lucis Pro 6 Plug-in User s Guide 29 Microtechnics

30 Both sliders applied Original (unprocessed) image Unprocessed Enhance: 93, Smooth: 1 Tie Together The Tie Together feature makes it easy to explore the many possibilities you image holds for artistic applications. This feature allows you to set a fixed difference between the values of the Enhance Detail and Smooth Detail sliders. With the Tie Together box checked, moving one slider causes the other slider to move by the same amount. Figure 24 shows a picture of a moth. The difference between the two slider values has been set to 20. The Enhance Detail slider is 243 and the Smooth Detail slider is 223. Windows Lucis Pro 6 Plug-in User s Guide 30 Microtechnics

31 By checking Tie Together and moving one slider, you can view all the possible image variations up and down the slider scale that result from the difference between the two slider values being equal to 20. One such variation is shown in Figure 25, which has the Enhance Detail slider set to 37 and the Smooth Detail slider set to 17. Artistic image variation Enhance: 243, Smooth: 223 Windows Lucis Pro 6 Plug-in User s Guide 31 Microtechnics

32 Another artistic image variation Enhance:37, Smooth: 17 Scan Lines For the most part, Lucis users leave the Scan Lines alone. If you reduce the number of Scan Lines, you start to create radial artifacts. Setting the Scan Lines to 1-3 creates the most dramatic effect. It can add interesting texture to your image. There are two boxes for the Scan Lines. The Preview Scan Lines value controls the Scan Lines used when creating the image in the preview window. This lets you easily experiment. But if you want the effect in the Lucis-processed image, you must also change the number of Processing Scan Lines Windows Lucis Pro 6 Plug-in User s Guide 32 Microtechnics

33 If you drastically smooth an image, you may want to increase the number of Scan Lines to remove radial artifacts that could appear. Below is a description of how Scan Lines work and how you might want to change them. Lucis operates by determining relative intensities, the intensity variations between pixels. When measuring the intensity differences between pixels Lucis compares each pixel to every other pixel along hundreds of radial lines called scan lines. Because pixels are a finite size and the number of scan lines is not infinite, you can sometimes see radial artifacts in the image depending on the Lucis processing parameters chosen. Increasing the number of scan lines will eliminate these radial artifacts if they are observed. With Lucis Pro you can alter the number of Scan Lines that Lucis uses to create the Preview Window image (the Preview Scan Lines) and the number of Scan Lines that Lucis will use when processing the image (the Processing Scan Lines). The values entered for the Scan Lines results in Lucis processing along 8 times that number of scan lines. The greater the number of Scan Lines, the more computationally intensive the image processing and the longer it will take. So, for example, if you increase the number of Preview Scan Lines you may find that the preview window changes too slowly when you change Windows Lucis Pro 6 Plug-in User s Guide 33 Microtechnics

34 Lucis UI parameters. This is why users sometimes choose to look at the preview window with a lower number of Scan Lines than that chosen for full Lucis processing. Lucis Pro has a default value of 32 for both Preview and Processing Scan Lines. This value is actually multiplied by 8 during processing, so this results in the algorithm processing pixel contrast variations along 256 scan lines. This default value is usually high enough to eliminate any visible radial artifacts in the image. Below is an image that shows just the top of a building and some sky. If the Enhance Detail and Smooth Detail sliders are very close together and the Smooth Detail slider value is high, radial lines can be seen in the sky (next image). Original (unprocessed) image Windows Lucis Pro 6 Plug-in User s Guide 34 Microtechnics

35 Processed image, with radial artifacts: Enhance: 97, Smooth: 87, 8 Scan Lines The number of Scan Lines can be set to very low values (1-3) to deliberately create radial artifacts, as an artistic effect. Please visit the Usage Tips page at for more information. If you see any faint radial lines in the Preview Window image and you would like to eliminate these artifacts in the final processed image, try setting the Processing Scan Lines to 40 before processing your image. The image below has the Preview Scan Lines set to 40, which removes the radial line artifacts. However, note that this figure still shows some artifacts, notably the shadowing around the edges of the roof. This artifact is explained The Shadow Artifact section, below. Windows Lucis Pro 6 Plug-in User s Guide 35 Microtechnics

36 Processed image, with Scan Lines increased to eliminate radial artifacts Enhance: 97, Smooth: 87, 40 Scan Lines The Shadow Artifact The above image shows a shadowing artifact that, when it occurs, can t be removed by changing Lucis parameters. This shadowing artifact is a result of the extreme slider values used to produce this image, and the abrupt changes from light to dark from the roof to the sky. There is a light area in the sky near the dark parts of the roof and there is a dark area in the sky near the white part of the roof. This shadow artifact is a result of the relative nature of the Lucis processing. In order to map out contrast variances each pixel is being compared to every other pixel along hundreds of radial lines in two directions. So, in the above image, a blue Windows Lucis Pro 6 Plug-in User s Guide 36 Microtechnics

37 pixel from the sky that is near a dark part of the roof is relatively brighter than a blue pixel out in the middle of the sky surrounded by similar blue pixels. Thus, the pixels near the dark part of the roof are brightened, creating a bright shadow. Similarly, a blue pixel from the sky that is near a bright part of the roof is relatively darker than a blue pixel out in the middle of the sky surrounded by similar blue pixels. Therefore, the pixels near the bright part of the roof are darkened, creating a dark shadow. This type of artifact only occurs around discontinuities in the image (abrupt changes in intensity) and usually when applying the more extreme Lucis slider settings. For most images the contrasts vary enough that this artifact is not observable or only affects a small part of the image. Mix With Original Image Slider The Mix with Original Image slider lets you mix the processed image with a percentage of the original image. The percentages can be adjusted to control the proportions of the original and processed image that are mixed to create the final image. The image below shows an original image of some flowers. Windows Lucis Pro 6 Plug-in User s Guide 37 Microtechnics

38 Original (unprocessed) image The next image shows the same image where the detail is greatly enhanced using the Enhance Detail slider. Over-enhanced image- Enhance:27, Smooth: 1 The image below shows the image that is the result of mixing 25% of the processed image with 75% of the original image.

39 Mixed image Enhance: 27, Smooth: 1, Mixed 25% Windows Lucis Pro 6 Plug-in User s Guide 39 Microtechnics

40 Assign Original Image Color Slider The Lucis algorithm modifies image intensity information. Grayscale images are processed perfectly. For color images, there can be color shifts. The Assign Original Image Color slider allows you to assign all or a percentage of the original image s color to the processed image. The image below shows an original image of an eye. Original (unprocessed) image Unprocessed (Preview box unchecked) The next image shows the same image with the detail drastically enhanced using the Enhance Detail slider. There are some areas with orange tones in the eyelid. Windows Lucis Pro 6 Plug-in User s Guide 40 Microtechnics

41 Processed image with some patches of orange color shifts in the skin tones (look at the eyelid at the top left corner.) Enhance: 51, Smooth: 1 The image below is the same image, only the Assign Original Image Color slider has been moved to the 100% Original position. This assigns the original image s colors to the processed image and removes the color shifts caused by the Lucis processing. Windows Lucis Pro 6 Plug-in User s Guide 41 Microtechnics

42 Processed image, color corrected using the Assign Original Image Color slider. Enhance: 51, Smooth: 1, Color Assigned 100% Display Composite Image The Display Composite Image check box is available only in Split Channel mode. When the Display Composite Image check box is checked (the default condition), the Preview window shows the result of the Lucis processing on all the color channels. Uncheck the Display Composite Image box to view only the selected color channel as a grayscale image, as shown below. Windows Lucis Pro 6 Plug-in User s Guide 42 Microtechnics

43 Red channel only (Display Composite Image unchecked) Channel Weight When in Split Channel mode you can alter the amount that each channel will be weighed (count) towards the composite Lucis-processed image by altering the weight number associated with each channel. Click on the Weight column and the value can be altered from 0% (the channel is disabled) to 100% (the color channel is fully enabled and counted when calculating the composite image). The effect of altering the channel weight is shown in the Preview Window. This feature is Windows Lucis Pro 6 Plug-in User s Guide 43 Microtechnics

44 particularly useful for Fluorescence Microscopy and for developing new artistic effects. User-Defined Presets User-Defined Presets gives you the ability to save and apply up to 300 user-defined presets. Lucis Pro 6 processes each image differently; these presets will save editing time since you can adjust the settings to ensure the desired result in Lucis. This feature is easy to use. When you have the processed image settings you would like, click the Save New button and enter your Preset Name in the dialog. Assign a name to a user-defined preset Click OK to save your defined preset. Windows Lucis Pro 6 Plug-in User s Guide 44 Microtechnics

45 Saved preset To view and manage the presets you have available, click the Manage button. A window opens which shows your presets. You can rearrange them, delete them and move them up and down the list. Your Presets are saved in a file that you should back up (com.lucis.lucispro.xml). Please note that if you uninstall Lucis your preset file remains. You can reinstall Lucis and still have your presets. Lucis Preset File Locations: Windows 10: C:\Users\<username>\AppData\Roaming\Lucis Windows 7: C:\Users\<username>\AppData\Roaming\Lucis Windows 8.1: C:\Documents and Settings\<username>\Application Data\Lucis Windows Lucis Pro 6 Plug-in User s Guide 45 Microtechnics

46 User-defined preset manager Memory Tiling Because the Lucis algorithm processes the entire image at once, it can consume very large amounts of memory when used with a large image. In order to process images larger than can fit into the available memory, Lucis will divide the image into sections ( tiles ), process each section separately, and then reassemble them into the final image. This allows processing of images up to 4 GB in size. For users with at least 4 GB of RAM (Random Access Memory), images no larger than 250 MB (CS3) or 350 MB (CS4x64) should not require memory tiling. Windows Lucis Pro 6 Plug-in User s Guide 46 Microtechnics

47 Tiling is best avoided when possible. Processing an image in tiles takes significantly longer than processing it as a single piece and in some cases artifacts may appear at the edges of the tiles in areas of the image where the contrasts do not vary much, such as a clear blue sky. Because of the possibility of these artifacts, you will be warned before processing any image that is large enough to require tiling. The image below shows the warning dialog that appears when tiling is required. Tiling warning Windows Lucis Pro 6 Plug-in User s Guide 47 Microtechnics
