Subject: Can’t open adjustment layer

I scanned slides on a Mac with a Nikon coolscan IV and burned them onto a cd. Then I rushed home to my PC and copied the files to my harddrive and opened them (PS 7). Much to my dismay, I cannot create an adjustment layer. The icons are all dimmed at the bottom and the top of the layers pallette, there is nothing active. Every item in the Layer Menu is dimmed. I can, however, rotate the image under Image and sharpen under Filter. I went into explorer and right clicked properties and unchecked "read only"(on the file on my harddrive, NOT the CD) and tried various methods of closing files and PS and even rebooting, no luck.

Did I have some weird box checked in the save dialog box on the Mac that is doing this? I have done this before(same Mac, same scanner) without this problem occuring.

I humbly submit this to all you gurus out there. I hope I’m not doing something stupid.

Thanks in advance,

Steve

Is the image in 16 bit mode? Image>Mode>16 bit
If so, change it to 8.

That reminds me, I scanned these in 12 bit mode on the Nikon for the extra color info. Do I have to open these all in 8 bit mode in PS?

The only advantage to working in high bit color is to be able to make color corrections without introducing banding or posterization. 16-bit images must be converted to 8-bit for other uses.

So, to gain the most benefit from your scans, here’s what you do:
1. Scan the image in high-bit color, and when you make the scan, use your scanner software’s color correction tools to set the proper hilight and shadow points–don’t just blindly click the "scan" button. Set the hilight and shadow for each individual scan you make.

2. Open the high-bit images in Photoshop. Do all your color correction, using the "Levels" and "Curves" commands, until you are satisfied with the color.

3. Convert to 8-bit.

4. Perform all your other image manipulation.

I was wondering if I should do that. The whole setup is accessible to all graphics students. Needless to say, I have to recalibrate the monitor every trip. Even then, I’ve been wondering if there was any point to doing color corections on the scanner, as the scans sometimes look different when I get back to my "perfect" machine.
