These instructions are for Photoshop, but should apply to many other editing programs.
Note: if you want to produce images for a 1024 x 768 AV rather than 1400 x 1050 AV you will want to use 1024 for width and 768 for height.
- Open your image in PS. If it is a 16 bit tiff change it to 8 bit, if it is a jpeg – don’t worry – jpegs are 8 bit, so you can ignore this bit. Select Mode - 8 Bits/Channel from the menu.
- To change the pixel size of your image go to the menu bar and click on Image - Image Size...
- This will bring up a box that will allow you to change the pixel size, either by width or height.
- If your image is in landscape format (i.e. wider than high) then you want to set the width to 1400.
- If you image is in vertical or portrait format (i.e. higher than wide), then you want to set the height to 1050.
- Leave the ‘Resolution’ setting at its default of 72.
- Most likely you will be reducing the pixel size of a larger image. You should use the drop down menu at the bottom of the box, and select ‘Bucubic Sharper’. If the image is already less than 1400 pixels wide and 1050 pixels high, then you probably shouuld not enlarge it! Submitting it as is will be fine. Enlarging an image is not generally a good idea since it will lose quality.
- Click the OK button to actually resize the image.
- After you have resized the image, it may look small on your screen. Press Ctrl-0 (zero) and it will be displayed so that it fills the available screen space.
- The image is now the correct pixel size and should be renamed and saved as a separate file.
