I bet the GIMP, being open-sourced and likely quite efficient, is fast, right?


The most taxing thing I ever have to do with it is rotate images. I've never run into anything nearly as resource-intensive as converting a RAW file, for instance.

I'm going to have to get more comfortable with GIMP, since Photoshop went cloud/subscription-only. When I next upgrade my PC, I doubt I'll be able to get the old Photoshop license transferred to the new machine.

It looks like GIMP has plenty of features, but after using Photoshop for years (for typical photos and also astrophotos that often need extensive post processing), GIMP takes some getting used to. Some operations seem slower than Photoshop, like drawing a rectangular selection? Also, GIMP doesn't seem to like opening 16-bit/channel TIFF files -- I think it converts them to 8-bit. Somewhere, I heard that GIMP was soon going to have 16bit/channel support?

I'm interested in circular (not oval) cropping. I don't seem to be able to do it with Irfanview or Paint. Would GIMP be better? Thanks

That's the very reason I started with GIMP a few years ago. Now that I'm comfortable with it, I'll even use it for processing art prints.

Thanks everyone. I found the site and will be downloading it this evening.

Thanks again.

I imagine if I have any questions I can ask here right?!

I have refrained from comments so far because this is a trigger issue with me. There are things that I would like to do in post processing but can't. I feel that the program instructions and help sections are so bad that I'm hoping the writers have their own special place in Hades.
I hear good things about GIMP and I don't doubt that the users are telling the truth. And I downloaded a copy for the specific purpose of making a circular crop. I would like to make composite photos that appear as overlapped coins like some of the auction advertising shows.
The first thing I did was go to the help section to find circular crop - and this should be one of the most basic and common of actions done in post processing. GIMP doesn't even have an alphabetized list of topics. How basic is that? Every modern technical manual written for the Western world has an alphabetized index. Not GIMP.
I know that if I set aside six weeks to discover all the features of their wonderful product, I would have only a 50/50 chance of cracking the code. So I quit. Just like with all the other programs. In fact, I've done this so often, that I created a folder for post processing programs that fall short of my needs. It's appropriately named "Crop Circles."
If someone wants to take on the Herculean task translation product instructions into user instructions they should be prepared to dedicate a great deal of time.
My frustration is compounded because I see it as one more supply side product that cares nothing for the consumer's wants or needs.

The Gimp (it's not an acronym, just a name) is not for the faint of heart. It's advanced graphics software for people who do graphics professionally, and requires a steep learning curve even for experienced Photoshop folks. It is not for beginners. I've been using it for ten years and barely know enough to do what I need it to do.

Circular crops in the Gimp are the last - and most difficult - thing necessary for coin photography which I learned. To this day, I do not like doing circle crops in the Gimp. That's why you don't see me post round images.

Can circle crops be done on JPG's or can this only be done on RAW files? I remember one program I tried to use said only rectangular crops could be done on JPG's.

Thanks SD, I use Irfanview mostly. Cropping a circle should be no harder than clicking on a circular crop icon and then clicking on your photo. You could use a three point method, center and radius, chosen size or fixed size. Simple and popular but not available. And that is why I wish bad things on the program writers. It's not your fault and I appreciate your help.
Don't hate me, this stuff makes me irrational. I am not in my happy place. I need a cookie.

I stand corrected on the acronym. I'm still using it as a word.

A circle crop creates the need for a transparency if you want a transparent background, which .jpg's aren't capable of. You'd probably have to export the result as a .png or create your own square background to your taste.

How to circle crop in GIMP:

http://goccf.com/t/74327&whichpage=2

This was most helpful to me when I started. I found GIMP to be very similar to older photoshops. I'm not even going to bother with Photoshop for creating coin images. I use Lightroom for all the other photography.

That's my favourite post here regarding GIMP and that's pretty much the process I use every time making coin photos now.

I appreciate all the help. When I can't do something, I get as cranky as a child. I may not get to this right away, but I'm going to bookmark the Gimp tutorials and hit it later. Thanks.
