:<<increase the dynamic range>> I haven't tried that yet. Do you have feel for what it is :actually doing? Sounds like it may be taking the 256 color limit of 3DS and 'spreading' the :range. Sounds like an interesting idea. When Photoshop adjusts the levels of an image it is shifting the lighter pixels towards white and the darker pixels towards black. You can also control where the middel gray falls but it usually not necessary. You should work with either Grayscale or 24-bit color images. These have a continuous range of values to work with and you will get less artifacts than working with 8-bit paletted color images. 3DS doesn't have a 256 color limit. Some of the outpupt formats are 8-bit 256 color formats and some are 24-bit 16.7 million color formats. TGA and TIF usually work best. Most printers and printer drivers work internally in 24-bit color so you really don't gain anything by using 8-bit images. :<<don't over compensate>> What happens if you do 'over compensate'? Is that where the :banding comes in? Yes, if you stretch a narrow range of values too much you get banding. :What kind of hardcopy / printer do you have? What print driver are you using? For the proofs that we print in-house we print to a Seiko postscript color thermal printer using windows postscript driver. :Thanks for the interesting idea, I'm off to do some 'stretching' …(g)… :Russ :Insight Development have fun <g> Terry Gilbert
