Trouble with big TIFFS

Trouble with big TIFFS

Post by Eastwel » Sun, 06 Jul 2003 05:02:28



I am having serious trouble with a series of large(c.23mb) 32bit TIFF files
that originally came from a FinePixS2 Pro digital camera. They display
perfectly in the Windows Picture and Fax viewer, and also print superbly from
this programme, both in colour and B+W (using my Canon S800 set to monochrome-I
have not yet been able to greyscale the picture). But the Picture and Fax
Viewer tells me it is a Corel Paint 7.0 image, and that it was created on a
FinePixS2Pro digital camera. It is 3024x2016. But... if I use Corel Paint 7.0
to open it, it looks horrible, with a grainy texture, and distorted
colours(very prominent greens and reds.

But this is a vital series of photos, and I really need to use them. I can't
understand why the images work perfectly from Windows Picture and Fax Viewer,
and badly from everything else-and of course, I can't edit them from this
programme.Have I hit a specialised form of TIFF that needs special filters?
Also, why does Windows say they are Corel Paint 7.0 images, and not TIFF's? It
is not by any chance picking up on the fact that I have Corel Paint 7.0 on this
machine? Have  Incidentally, I believe the photographer uses a Mac.

I'd be most grateful for any help!

Try right-clicking the image when you see the file listed in
windows-explorer then select "Open with...".
Now chose your usual image processing program, check "always open with
this application".

Now your association between TIFF and that application should be
repaired.

I think it could depend on different color spaces you use with the camera,
Windows and Photopaint.
I think Photopaint 7 could handle CMYKs. But that's not the problem as the
color space of the picture is certanly RGB.
But: Not every RGB is the same.
The camera might use S-RGB for example (I suppose that). The Windows software
uses this space too, so that may be the reason why it looks good here.
But Photopaint can handle different colorspaces. One that defines the internal
RGB-mode, one for the monitor and several more.
Depending on the task you want to do with the picture (print, internet,...)
you have also a CMYK profile.
So it could be that Photopaint shows how the picture would look when it's
printed.
You can define the profiles at the color management dialog. Change settings
there and see what's happening!
