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.

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).

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 &...

you can download and use the Adobe Creative Suite Cleaner Tool to clear the errors in the uninstall..
Download from the following link and try that:

Download and "Run as Administrator" and then restart your machine.

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 light source 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 ...

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"

From the man page:
-s (-short)
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,

Short Answer
No, decoding is not guaranteed to always be the same. However, the differences are guaranteed to be very, very small.

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 ...

Exposure Fusion Software:
Enfuse - Enfuse merges different exposures of the same scene to produce an image that looks much like a tone-mapped image. Standalone command line tool, open-source, Windows, OSX, Linux compatible.

Hugin - Integrates Enfuse fully, Windows, OS X, Linux ...

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 ...

If you are talking about JPEG files, then the utility jpeginfo is exactly what you're looking for. It can check files for different types of JPEG errors and corruption and either return an error code (the most useful thing for scripting), or just delete files with errors.
I use this as part of my initial file transfer, to make sure everything copied okay ...

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 ...

You answer lies in Lightroom and this free software plugin for lightroom http://lrtimelapse.com/
NOTE: this will only work for free for short timelapse segments. Anything over 400 images requires a license.
The great thing about using lightroom for a timelapse is that you can easily crop,edit thousands of images with a simple click. You can then make 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 ...

I think you'll be fine. Look at the case of Aperture, discontinued by Apple. Adobe offers an Aperture import plug-in.
Lightroom's catalog is an SQLite database and much of the data stored within it is in XML format so the data is very accessible to programmers if the need arises. In the unlikely event that Adobe and Lightroom ceased to exist, it would easy ...

The image I uploaded was rejected because it was under 300 DPI.
The DPI is just a number which has no relevance to a digital image. It relates only to printing and not the quality or resolution of the image itself.
If you change the number to 300 DPI in an editor, it should be accepted.
As you have Windows 10 and presumably use assistive technology to e....

If you are looking for something closer in spirit to Aperture or Lightroom, consider Darktable. Open source, all that.
http://www.darktable.org/
Its not as polished as Aperture or Lightroom, but it works, and is free. It has an active development group, and it gets better all the time.

The official stance is clearly to be coy with what exactly the product category is, which is why you're unsatisfied with the answers you're getting. As Craig Walker points out, the description tag in the HTML used for Adobe's web pages about Lightroom says:
Lightroom is the leading software for digital photography editing.
You can find this "official" ...

Lightroom is the way to go. Download the trial and give it a try, though I do recommend reading a bit or watching a few videos first to get the most out of your trial.
Lightroom will let you do whatever you wish on the file system side, and then offer flexibility beyond it. This is important, because this NAS won't be your last, and in fact, you may have ...

Photoshop's Batch command can do this. You would essentially 'record' yourself performing the crop etc once, then run the recording on all the files you want. If you want to automatically resize the smaller images you would have to do a little scripting.
Irfanview also has a comprehensive image batch processor but might require a bit of experimentation to ...

First of all, in optics, only light adds up and darkness does not. Make sure that your algorithm does not bleed dark pixels outwards their original location. Resulting pixels should rather resemble maximum of nearby source pixels than average. Or, to be even more exact, you'd be summing up logarithms of affecting source pixels.
Another possible cause why ...

There are two distinct steps to producing the images that are frequently labelled "HDR":
Exposure blending: merging multiple low dynamic range images into one image with higher dynamic range.
Tonemapping: processing that high dynamic range image into a low dynamic range image suitable for viewing on standard [low dynamic range] equipment (such as regular ...
