Why not use DPP & output TIFF to Gimp.

I've tried doing that, and can't get Gimp's Gaussian blur to work with the TIFF. Works fine with JPEG. Anybody have any ideas why?

This is what I get where do I get this file?

I belive this is a bit late, since the post is 7 month ago, but I found this description of the problem.

great tips

This is great thanks...

Does anyone know how to make Gimp brushes less laggy ? Whenever I try it on my computer the brushes seem to have sort of mild inertia to them. I am on W7x64 dual core 2.7 MHz Pentium, it should be plenty fast for that.

Any tuturials of the recent release?

Re-Gimp

I like to take photos of Airline traffic on airways mainly about 20-30,000ft with my SX20IS 20x zoom and although just a small sensor bridge, it manages some quite good results in good light.

I would like to know If there are any general touch-up tricks In gimp to smooth out some of the image noise (lots of blue sky and small plane) I genaraly use the blur - selective about 2-3 percent then the N/L filter with the recommended amount of edge shapen, then I sharpen the Image between 25-50 percent.
I have even tried zooming In about 400 percent and doing some touch-up with the colour picker then airbrushing the edges of the plane, before either - Filling In with Bucket or manualy by Airbrush to smoothen out the noise.
I am not confident enough yet to try the more advanced stuff so any settings of the the above that would help me ie - N/L settings for my type of subject would be very mutch appreciated.

Cheers In advance......

Ditto. I downloaded it but the tutorial is completely different. I am not familiar with the old versions so I cant seem to find some of the stuff in the new version.

This is not really "touch-up tricks" as requested, but you mentioned noise reduction, pagman, and I use Noiseware community edition. it works pretty well except it's pretty strong; I read a recommendation to only use the "weaker noise" option and that's what I always use. Oh, and it's free.

Should install happily

Thanks, downloaded it

I'm not sure if this has been mentioned before but Gimp has a newest version. 2.10.8 It is an amazing upgrade from the last one.
It is much faster and requires less resources. It has new filters too.
Try it, amazing. For a raw converter I use Fast Stone, great program. I am trying to use the latest Darktable some with Gimp, for a raw converter, seems to be good also but kind of cluncky.

Probably. People who have posted previously will get notified when there's a new post (that's why I saw your post). What's your question?

I have downloaded their latest version 2 10-30 but wish to use the up scaling tool to increase the pixal size of some Tiffs, I was wondering how large can I up scale them without causing too much damage to the Image Quailty?

I'd suggest just experimenting. Scale up and then zoom in to 100% (View menu, or just hit the "1" key). Then also enable "dot for dot" in the view menu to make sure every image pixel matches a pixel on your screen. If it looks blocky, then you went too far and you should use "undo" and try upscaling by a bit less.

Also note that the Gimp has more than one way to upscale. There's the Scale option in the Image menu, which gives you several interpolation choices. But G'MIC-Qt (in the Filters menu) also has several scaling tools under "repair".
