I’ve asked this on another forum, nobody can figure this out, I hope anyone can help 😉

My problem: After saving, the shading or banding of colors is rough/not smooth.

When looking at the final product within PS, it looks perfect (smooth color transitions etc. No matter how I save the image (BMP/Jpg/etc) and setting the details to MAX, when viewing it with say IE Explorer, the banding is present. Now closing PS, and re-opening that bmp/jpg, the colors look smooth and transitioned.

I’m using a Radeon9800 pro card / 19" at 16bits.(1280×1024).

I feel so hopeless because after all of the hard work, on MY end it looks perfect. When viewed in explorer after u/l the wallpaper, it looks terrible. Heres what my color settings look like: (Thank you very much for the help, I need it: )

Sigh.

No, saving doesn’t degrade anything.

What you’re seeing is the presence of color management in Photoshop, and the lack of color management in the other applications you’re using the view the images.

Forgot to add, here’s a wallpaper done in the past. Look towards the far left, the ‘spotlight’ blue pointing up. Theres banding in the blue (and others places). In PS its perect, in Windows Picture Viewer perfect.

When set as a wallpaper? banding. When viewed through IE Explorer, color banding. Im working on generating clientel and I would rather customers see the quality of the real work – not this uglyness 😉

thx

Why just 16 bit? Try turn it up to 24 bit instead.

SK,

That image you linked looks perfectly smooth in the colors to me, whether viewed in IE6 or set as a wallpaper. I’m not sure what your problem is if you’re seeing banding in that image, but I’d think it to be some sort of display settings problem or perhaps a monitor hardware issue.

Regards,

Daryl

Same here. I see no banding at all in either Safari or IE.

Well thats just WEIRD. Like I said, if I look at other peoples graphic work in 16 bit, color looks perfect in IE or Windows image viewed.

NOW 😉 To Tom saying turn up the resolution, that would be fine but its potential customers on the outside thats important and most everyone runs at 16 bit. Now, I just took and set the ‘banding’ photo (that looks perfect in PS) and stuck it as a wallpaper – viola, color banding. Flipping to 32 bit fixes it, but most dont run there. Its just so strange….

The only time I’ve ever seen color banding, was when I reduced the color depth of an image to a rather low value such as 8-bit. I can’t say I’ve ever seen an image that is of higher color depth than the monitor settings ever display banding, and the same holds true of the image here. Whether viewed at 8- or 16-bit color depth on the monitor, I still observe no banding in IE or as wallpaper.

Almost nothing will look good in 15/16 bit display mode.

Well, if there’s anything than can cause banding then it’s certainly to set your graphic card to only 16 bit color.

NOW 😉 To Tom saying turn up the resolution, that would be fine but its potential customers on the outside thats
important and most everyone runs at 16 bit.

If it’s me you’re calling Tom then I’ve never said that you should turn up the resolution. I’ve said that you should turn up the color depth of your graphic card. 🙂

Now, I just took and set the ‘banding’ photo (that looks perfect in PS) and stuck it as a wallpaper – viola, color banding. Flipping to 32 bit fixes it,

Well there you have it. 🙂

but most dont run there.

Have you asked them?
I don’t know anybody working with colors that set their graphic card to only 16 bit because it’s well known that it causes banding. 16 bit gives you access to only 65536 colors. 24 or 32 bit gives you 16,7 millions (also called true color).

Madsen,
I was refering to the resolution from the other person that helped 😉

I’ve looked and looked, online and in all the tabs, on the Radeon9800 pro, I dont see anything to ‘increase’ color depth.

The only way to do that is with the resolution slider….

Thanks a bunch!

Shifter – it’s on the bottom left of the display properties panel.

Okay. Sorry then.

Usually it’s not a setting in the graphic card driver. It’s build into Windows and you’ll find it under Control Panel > Display > Settings. It’s called Color Quality in Windows and how many colors you can choose there depends on the graphic card driver. Some can choose 8, 16, 24 and 32 bit. Others can only choose 16 or 32 bit for instance. I have a Matrox Parhelia and can only choose between 16 and 32 bit so I have chosen 32 bit because 16 bit looks awful.

It is done via the control panel. I would be very surprised to learn that the Radeon 9800 did not support 32 bit color depth especially as my nVidia card does.

everyone runs at 16 bit.

Huh? Where’d you get that stat from? I know of no one who’s running at 16-bit, be they computer-literate or as-it-came-out-of-the-box.

‘zactly. Most run at "true color" max setting which is usually 24 or 32 bit.

If I even save as a PSD the quality of photos are degraded when I open up the file again. Any help with this?

Thank you!

Sarah – read the existing responses.

Saving as PSD doesn’t "degrade" anything in the image.
