[help] Decreasing Colours

Hi!

I own a PowerBook Duo 280c. The screen can have two modes:

- 640x480 pixels with 256 colours;

- 640x400 pixels with 16 bits.

Resizing the image is not a problem.

The problem I have is when I want to transform a wallpaper done in 32 bits, the rendering in 16 bits or 256 colours of the nuances is awful. For example, the classic wallpaper for OS X (the blue one) is not great when I put it on my PB, even in 16 bits (the nuances disappear).

How is it possible to decrease correctly the colours, in order to have a good rendering?

I have tried with Photoshop but the result is not very good, and I think I don't know how to parameter correctly the good tools. I own Photoshop 7 and Photoshop Elements 2 for PC, and Photoshop 4 for Macintosh. Then if you want to give me tricks with Photoshop, there would be no problem.

Thanks in advance for your help and best regards,

Don.

You can't get the same look of a 32bit-color wallpaper in 256 colormode, you have to compromise when you can't use 32bit-color, find what looks the least ugly. <_
