Pixel Density - High Resolution Vs Low Resolution 1. The resolution of a digital image is the fineness of detail and is measured in pixels per inch (ppi).

3 Pixel Density - High Resolution Vs Low Resolution 1. The resolution of a digital image is the fineness of detail and is measured in pixels per inch (ppi). The more pixels per inch, the greater the resolution and the better an image resolves to our eye. Generally, an image with a higher resolution produces a higher quality printed image. 2. Pixel dimensions measure the total number of pixels along an image s width and height. 3. In Photoshop, you can see the resolution of an image and its dimensions using the Image Size Menu (choose Image > Image Size). 4. You can also use Photoshop to add pixels or remove pixels, and make an image larger or smaller. This is known as resampling.

4 To Resample an Image 1. Choose Image > Image Size. 2. Tick the Resample box on. 3. Input desired resolution. 4. Input chosen width and height values, you can choose you preferred method of measurement. Make sure the chain-link icon is on, this option automatically changes the width as you change the height, and vice versa. 5. To restore the initial values displayed in the Image Size dialog box, hold down Alt (Windows) or Option (Mac OS), and click Reset.

5 Cropping and Straightening an Image We can use the crop tool in Photoshop to removing portions of a photo to create focus or strengthen the composition. We can also straighten out horizon line by using the straighten option inside the crop tool. 1. From the toolbar, select the Crop Tool. 2. Draw a new cropping area or you can drag the corner handles to specify your edges. 3. (Optional) Specify the Crop options using the Control bar. 4. The crop options allow us to choose size and proportions, change overlay options, and delete cropped pixels. We can also use Content-Aware technology to intelligently fill in the gaps when you use the Crop tool for straightening or rotating an image, or expanding your canvas beyond the image's original size. This is a highly useful tool. 5. It s is advised that you deselect the option to delete cropped pixels. This will apply a non-destructive crop. Non-destructive cropping does not delete any pixels. 6. Press Enter (Windows) or Return (Mac OS) to crop the photo. File Types JPEG: A commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable trade-off between storage size and image quality. JPEG is a common file format. PSD: Photoshop files have default file extension as.psd, which stands for "Photoshop Document." A PSD file stores an image with support for most imaging options available in Photoshop. These include layers with masks, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. It is not a common file format so is not suitable for sharing or uploading to the internet.

6 TIFF: A computer file format for storing raster graphics images, popular among photographers. The TIFF format is widely supported by image-manipulation applications including Photoshop, they can also save layers. TIFF file sizes are very large. Save in JPEG Format 1. Choose File > Save As, and choose JPEG from the Format menu. 2. In the JPEG Options dialog box, specify your quality (12 is recommended). JPEG Format Options Specifies the format of your JPEG file. We encourage Baseline ( Standard ) as it uses a format recognized by most web browsers.

7 Save in PSD Format 1. Choose File > Save As, and choose PSD from the Format menu. 2. Name the file, and click Save.
