Hi

I'm fairly new to Photoshop and have been asked to supply a image for use as a desktop wallpaper as follows:

2133x1600px

150dpi

24bit

Jpeg

From what I can work out PS doesn't support 24bit jpegs, but thought I'd check on here to see if anyone can help!

Cheers


Pete

    24 is the composite value, and in your title tab, it would be depicted as RGB/8

    150 dpi (or ppi) is how many of those pixels will print to an inch of paper if they wanted a print out of the wallpaper. 2133 px/150 ppi = 14.22 inches on the long side.

    But yeah, you want your work accepted, so go with their specs.

      Hi petemccormack

      Photoshop lists the bit depth as Bits/Channel. There are 3 channels in an RGB image. So a JPEG which by definition is an RGB image with 8bits/channel will actually be a 24 bit image. No conversion necissary. Leave it as RGB and  8bit/channel in photoshop and work on 2133x1600px 150dpi  image.It will be fine.


      Regards

        Almost all JPEGs are 24 bits. 3 x 8 bits. Make sure it is RGB, and the JPEG will be 24 bit.
