Photographic workflow applications such as Adobe Lightroom and Apple's Aperture provide this sort of history as a built in part of their functionality.
When you edit a RAW file in these, no changes are ever made to the original image. Instead, they are saved as 'instructions' separately. Thus, you can see a history of all changes made, and with a click ...

If you want to just select an area click on the marquee tool in the toolbar. Once selected, you'll see a drop down at the top called Style with the default set to Normal. Select Fixed Size from the option and enter the values into the right boxes. Notice, with this option, dragging the mouse is no longer necessary as the box is a fixed size. You just need to ...

As far as I know, the best bet for Linux is Darktable. Workflow management with raw and JPEG editing all in one.

The tint slider takes care of a couple things. First off, from a color perception standpoint, there are two major axes that the cones of our eyes base color perception on: blue/yellow and magenta/green. There are some specific nuances related to these axes, however the most important is that they represent opposite colors that the human eye can not see ...

If you don't have it, I'd recommend Adobe Lightroom and then use Gimp for the occasional 'advanced' edit. Most of the reasons are already outlined in this question. Photoshop is nice, but its not meant to deal with the huge number of photographs you can do from a real shoot. Its a workflow thing.
I find 90%+ of the basic tweaks I need can be done in ...

First of all it's important to understand the difference between HDR and tonemapping. HDR is a technique to capture images which contain a huge variety of brightness information. However most people lack high dynamic range monitors to show this information. If you simply scale the large range of brightnesses down to a smaller range, you end up with an image ...

Simply select and copy the screen/glare you want to overlay, and paste it to a new layer. Set the Blending Mode to Hard Light. Then paste in your product image in a new layer and place it underneath the glare layer (you will obviously need to do some jiggery pokery to fit this image onto the screen in the photo).
Result:

I'd guess it's as simple as selecting the subject in Photoshop - with a tad more care & attention than I've used below, then leeching out the saturation in the background & tonally balancing towards a sepia effect.
As a very quick demo I did the same thing but made it a pretty garish purple instead.
Once you have your mask you can treat inside &...

There are two ways to simulate a Graduated ND filter by software and they both have different disadvantages and advantages, compared to an physical filter:
H/W Filter
Pro: A H/W filer gives you results immediately which you can see while you compose.
Con: On the other hand, the effect is fixed in gradation and shape.
Software Effect
Pro: Adjustable in ...

If you have to ask, then Photoshop is NOT worth the money.
Only if you need Photoshop, will it ever be worth the money. It is expensive because people who use it find that it pays them back easily.
If you do not know what you need, then you do not need Photoshop.
Photoshop is a tool that can help you solve problems and create creative solutions in your ...

If you don't know the crop boundary then you can use Fred Weinhaus's multicrop script (this script also uses Imagemagick). The script also handles different photo sizes and rotated images.
Example (book covers):
Scanned image (input.tiff):
multicrop input.tiff output.tiff
Result:
output-0.tiff:
output-1.tiff:

Lightroom always uses a catalog to store your edits, however you can disable the backup notifications.
Go to: Edit->Catalog Settings (PC) OR Lightroom->Catalog Settings (Mac)
Set: "Back up catalog" to "Never"

I think the main problem is one of dynamic range, your algorithm is probably right but you're working on the wrong type of data.
A point lightsource that would otherwise clip and go pure white gets spread over a larger area by a defocussed lens, so that it forms a disc that isn't as bright and therefore doesn't clip.
That's why you get those nice circles ...

The entire point of raw files is to save the full unprocessed output of the sensor, there are no programs that edit raw files because if you do any editing it's no longer the raw output and you are better off generating a TIFF from the raw and editing that.
A note about resizing - most camera sensors have a pattern of red, green and blue pixels, where each ...

Darktable handles JPEGs almost as RAWs. It just activates different processing modules by default, and e.g. the demosaicing module is of no effect for obvious reasons. See the Darktables module dependencies diagram. This diagramm is loosely processed from the bottom to the top by darktable. So, the arrows are followed in reverse direction. The user can ...

No, decoding is not guaranteed to always be the same. However, the differences are guaranteed to be very, very small.
ISO Specifications
The International Organization for Standardization (ISO) specifications for JPEG has the following specifications for decoders (emphasis mine):
A decoder shall
a) with appropriate accuracy, convert ...

You can't resize RAW files per se. You can crop them in a RAW editor like Adobe Camera RAW, and the crop information will be stored in the sidecar XMP file, but the RAW file itself remains the same.
This depends on your editor, but generally when you 'edit' a RAW file you are just storing settings in a 'sidecar' file. When you re-open the RAW file, the ...

IP-Slicer perl script can create slices which can stuck together into a ball. You can define the number of slices.
The following command will create 12 slices, where the sphere circumference is 1500 pixels.

Short output format. Prints tag names instead of descriptions.
Add up to 3 -s options for even shorter formats:

-s -s -s - print values only
so,

Since you can't do anything about the color management of other people's monitors, the best you can do is:
Make sure your own system is properly color managed (see other questions here on color management). That way, you are at least certain that you're starting from a known point. This is really worth doing even though it takes some effort and probably a ...

The easiest way to do this is using a smart collection. You can use the Has Adjustments filter to show just edited photos, or the Edit Date filter to choose photos edited within a specific time period.
I have a smart collection called "Edited this week" which is great for easily getting back to the photos I've recently worked on.

Yes they can, but there are some significant caveats. Although they can be run alone, the plugins were not designed to be used as a standalone application.
If you have the folder with the executable file (NOT the plugin file) for a specific Nik suite plugin open on your desktop and drag a jpeg or tiff file and drop it onto the executable file (NOT into a ...

I like to think about the tone curve in terms of a function:
y = t(x)
The input value x to the function is a pixel value from the source image, which is actually the brightness of that pixel. Let's say the values of x can range from 0.0 (black) to 1.0 (white), with all the gray tones represented as real numbers between 0 and 1 (to simplify things a bit let'...

Expanding on Miguel's answer with an illustration, I have in the center a test image gradient with no curve adjustment. On the left I am using a steep curve that pushes my shades of grey closer to extreme black or white, spreading out values near middle grey over a larger range of shades. The effect is that the extreme dark and light areas encroach more on ...

This particular logo is easy, because:
It's only three colors
It's relatively simple vector art
there's a simple outline around the shapes
The goal is reconstruction, not preservation of a masterpiece
That means you don't need to light it very well and you don't need to worry too much about noise. Take a photograph straight down, and notice any sources of ...
