Formatting a digital image file for Zapplication using Photoshop

1. Make the longer dimension exactly 1920 pixels
   1. In the menu (top of screen), select "Image" then click on "Image Size"
   2. Make sure both "Resample Image" and "Constrain Proportions" (bottom of window) are checked
   3. In the top two boxes of this window (in the "Pixel Dimensions" section), determine whether the width or height is greater.
   4. Change the larger of these two numbers to 1920.
   5. Click "OK".
2. Convert the image shape to a square, filling the excess area with black
   1. In the menu (top of screen), select "Image" then click on "Canvas Size"
   2. If the units of measure is not "pixels" (it's probably "inches") change it to "pixels" using the drop-boxes.
   3. One of the dimensions will specify "1920" and the other will specify something less than that. Change the smaller number to 1920.
   4. In the bottom of the window, change the "Canvas extension color" to "black".
   5. Click "OK".
3. Convert the file's color space to sRGB (if it's not that already).
   1. Note: The location of this feature changes in different versions of Photoshop. I'll describe how to do it in CS. In CS2, look in "File" instead of "Image".
   2. In the menu (top of screen), select "Image" then "Mode" then "Convert to Profile". (Note: do not use "Assign Profile"!
   3. For the "Destination Profile", select "sRGB". (It may have some characters after that, e.g. IEC61966-2.1).
   4. Click "OK".
4. Save the file in JPEG format so that the size is not greater then 1.8 megabytes.
   1. In the menu (top of screen), select "File" and "Save As".
   2. In the "Save in" box, select a location where you will be able to find the file. (For example, desktop, or your M: drive.)
   3. In the "File name" box change the name if you want. (Zapplication will assign its own name, so the name doesn't matter to Zapplication.)
   4. In the "Format" box, specify "JPEG"
   5. Click "Save".
   6. In the "JPEG Options" box that follows, slide the slider all the way to "large file" or change the "Quality" number to "12". (These will both achieve the same result.)
   7. Make sure that in "Format Options", "Baseline ('Standard')" is selected.
   8. Look at the first number in the "Size" section, right after the tilde (~). If this number is greater than 1800.0K then move the slider a bit to the left or change the "Quality" number to "11".
   9. Check the size setting.
      i. Reduce the "Quality" setting only as much as you must to get the file below 1800.0K. (Usually a Quality setting of "11" will do this.)
   10. Click "OK".
5. Close the file.
   1. Click the "X" (PC) or red dot (Mac) on the top of the file to close it.
