37 Watch your white point 8 HDR Tips? 1. Highlights 2. Shadows 3. Histogram in Photomatix 1. Set both WP and BP to zero in Photomatix and adjust contrast in Photoshop

38 Clean up your highlights 9 HDR Tips? 1. Smooth Highlights

39 Be Careful with Presets 10 HDR Tips? Presets are a starting point not a destination

40 Post Process 11 HDR Tips? 30% Photomatix 70% Photoshop

41 Noise 12 HDR Tips? 1. Noise from original image 2. Noise from HDR software Reduce noise early before HDR

42 Noise 13 HDR Tips? Use Filters to Finish Off Topaz Adjust

43 Creating Images for HDR

44 Creating Images for HDR Methods 1. Three RAWs (not the way that HDRsoft recommends) 2. Three Tiffs (Correct Chromatic Aberration in Camera RAW) 3. Five TIFFs (Three RAW files converted to tiffs(-2,0,+2) and create two additional files for -4 and +4) 4. Three JPGS 5. Five JPGS 6. PS RAWs( Creating a 32 bit HDR image using Photoshops Merge to HDR feature, saving it in EXR format and feeding it into Photomatix.

48 Creating Images for HDR And the winner is Based on these tests, I recommend to you to do following: 1.Shoot in RAW format. 2.Merge your HDRs using Photomatix and not in Photoshop to preserve the colors. 3.Convert your RAW files to TIFFs using a high-quality RAW converter to retain control over highlights and chromatic aberration. 4.If you have a scene with important highlight regions and your coverage of the dynamic range is close to the edge, you should develop additional TIFFs with a lower exposure value.

49 Extreme Dynamic Range HDR created from 11 exposures in steps of 1EV (1). The brightest (2) and the darkest exposure (3) are too far apart for a standard Auto Exposure Bracketing series found in most cameras today

50 Manual Exposure Method Preparation Put your camera into A mode (aperture priority mode). You will do the actual shoot in M mode, but the A mode allows you to easily measure the right shutter speeds for your scene. Choose the right aperture. This depends on the lighting of the scene and on the depth of field you are trying to accomplish. Choose the lowest possible ISO sensitivity to avoid noise in your photos. Put your camera into single-point focus mode. This lets you manually select the point that your camera should use to focus and to measure the exposure. Set your focus. You can use the autofocus to get your main subject in focus. Switch the AF off once that s done. Otherwise, your camera may decide to change the focus in the middle of the MEB series which would require you to start from scratch. Put your camera into spot metering mode. In this mode, only a small region around the active focus point is used to measure the exposure. The rest of the frame is ignored.

51 Measure the shutter speed for the longest exposure (darkest area. Memorize the shutter speed indicated by the camera. We will call this value L (for low). Depending on the amount of light available in the scene, L may be several seconds long. In this example L is 1.3s Measure the shutter speed for the shortest exposure (brightest area). Move the focus point to the brightest area of the scene. Memorize the shutter speed indicated by the camera. We will call this value H (for high). In the example, H is 1/200 seconds. Manual Exposure Method

52 Manual Exposure Method Taking the shots Camera mode: Put your camera into M mode, and make sure your aperture is set correctly (to the value you have chosen for the scene). Shutter speed: Set your shutter speed to L(1.3s) Shoot: Take a shot. Increase: Increase the shutter speed by 1 stop (three clicks of the wheel). Repeat: If your last shot was taken at or above the shutter speed H, take one final shot and you re done.

53 Manual Exposure Method Set Camera to AV Mode

54 Manual Exposure Method Set Aperture

55 Manual Exposure Method Point Camera at brightest Point and Meter 1/200s

56 Manual Exposure Method Point Camera at darkest Point and Meter 1.3s

57 Manual Exposure Method Set Camera to M Mode

58 Manual Exposure Method Set Shutter speed to 1.3s Take a shot

59 Manual Exposure Method Three clicks Take a shot etc, etc Until You get to 1/200s
