spot healing won’t work with TIFF and BMP?

I’ve recently moved to TIFF or BMP format for my scanned negatives and prints after I became frustrated with thte image quality of JPEG.

Anyone know why this is, or if maybe I’m doing something wrong? I’ve tried to tell my scanner software that the media (in this case B&W negative) is color to try to fool Photoshop into using the spot healing brush but I just get weird colors and tints that are unacceptable when I do this.

Why don’t you just save as .psd (photoshop file format) before doing anything
or just convert as black and white *after* doing healing brush stuffs. or just convert your B&W TIFF in RGB by Image>mode>RGB that will give you 3 channels but in "greyscale" result.

Hope this helps!

That’s a good tip, thanks!

Yes, that is correct.

It sounds like when you scanned as "B&W," what you actually did was scan as bitmap. Look at Image->Mode; it should be Grayscale or RGB Color, not Bitmap.

Bizarre, changing to RGB doesn’t work either. I’ll try to go back and scan it as color again and see if I can’t figure it out another way. I just don’t understand why Photoshop can’t/won’t work with B&W TIFFs.

Works okay here.

That tool should work on both RGB and greyscale images. Are you sure you didn’t select a text layer (or no layer at all)?

Well, in any case, I seem to have fixed it. My scanner software offers me the following options when scanning: What am I scanning: color negative, B&W negative, reflective print…What output do I want: 24 bit color, 48 bit color, 8 bit grayscale, 16 bit grayscale…What file format do I want: JPEG, multi-TIFF, TIFF, BMP…

Previously I was selecting B&W media, 16 bit grayscale output, and TIFF. Photoshop wouldn’t spot heal these files, still don’t know why. What I’ve done to get around it is I’m still scanning for B&W negative, but outputing the file as 24 bit color and TIFF format. Photoshop works fine with that. Strange limitation.

Because it does not work on 16-bit grayscale. You must convert to 8=bit grayscale for most of Photoshop’s tools to work.

16-bit files are only useful for large-scale color correction with Levels or Curves. For printing and manipulation, you should work with 8-bit grayscale.
