 Hi
 
 I want my animated gif to have specific time for each frame.
 
 How can i do it?
 
 For example: 
 
 Frame 1 - 2 seconds
 Frame 2 - 4 second
 etc.
 
 This is possible in photoshop, but i have not yet been able to do it in
 GIMP.

Use the layer names. xyz (1000ms) will show this layer for a second.

 Thank you very much indeed. Now I can forget all about the approach I
 thought I would look at and concentrate on those ways I know best - the
 methods suggested and demonstrated by Ralph Steinort.

Rolf please! ;-)

I think this is basically the same thing that you can do with the
channel mixer. 

In the top adjustment layer they do a crude desaturation by simply
removing it. You can do that in Gimp by adding a layer filled with black
and setting the mode to saturation.

I don't get what the lower layer does. I'll ask a friend an d report
back. Perhaps there is something interesting in it.

Nothing interesting. 

I just talked to John Arnold from http://photowalkthrough.com/ (worth to
look into even for Gimp users). He told me that this is an old method
and has less control than the channel mixer. 

The lower layer just rotates the colours. That leads to a different
luminosity and so to different monochrome output.

It works here as advertised. I just dropped it into the folder.

But wait - your message said:

That's a different script, this is called Darla-PurpleFringe.scm. Just

I think your camera is OK, the problem is your close up filter that
you use for enlarging the slides. These things are prone to CA. You can
get away with a lens made out of two glasses (called achromatic and
being expensive), but most of these things are made out of a single
glass and mess up the colours. I never have heard about an apochromatic
lens to put in front of a point and shoot. 

You can try to use your camera without this lens in macro mode and crop
the image later in GIMP. With luck there is enough resolution left.

 No idea what exactly IDimage is doing but it probably needs to be
 updated for GIMP 2.4 then.

Or perhaps IDimage can call gimp-remote instead of gimp? If that doesn't
work one could make gimp a link to gimp-remote. As far as I know it
behaves like gimp when no other instance of GIMP is running.

Now I have started a video podcast or screencast about photography and
