I am familiar with adobe photoshop 6.0 .I need to
implement this Rules(dv2005)(below) to the photos .
#################
(For digital camera)
It must have a resolution of 320 pixels wide
by 240 pixels high, and a color depth of either
24-bit color, 8-bit color, or 8-bit grayscale.
Only the 320×240 resolution will be accepted.
(For scanner )
If a photographic print is scanned, the print
must be exactly 2 inches by 2 inches (50mm x 50mm) square. It must be scanned at a resolution of 150 dots per
inch (dpi) and with a color depth of either 24-bit color, 8-bit color, or 8-bit grayscale.

The problem is the rule that you have listed. (For digital camera)

320 x 240 is the absolute size of the image in pixels, not the resolution. "Resolution" which is measured in Dots Per Inch (dpi) isn’t given.

The pixel size of the digital camera picture is 320 x 240 = 76,800 pixels. The printed dimensions of the picture will vary with the resolution (dpi)

300dpi = (320 pixels/300dpi) by (240 pixels/300dpi) = 1.07" by .8" 150dpi = (320 pixels/150dpi) by (240 pixels/150dpi) = 2.13" by 1.6" 120dpi = (320 pixels/120dpi) by (240 pixels/120dpi) = 2.67" by 2"

Hope This Helps

It sounds like your need to change the dpi (pixels per inch) first, press OK to get out of that window and apply the changes, then go back in and change the print size of the image. I could be wrong but I thought I would add my ‘two cents’ 🙂
