If you find that hitting the "auto" button in the GIMP levels dialog generally does the thing you're looking for, you can batch that as described here.
Specifically, you would put this script:
(define (batch-auto-levels pattern)
(let* ((filelist (cadr (file-glob pattern 1))))
(while (not (null? filelist))
(let* ((filename (car filelist))
I use CC search to find creative commons images. It's a meta-search engine and it searches sites like Flickr and Wikimedia Commons. You could upload your work to one of the searched sites, indicate under what creative commons licence the images fall and describe them as much as possible (keywords, location).
Adding some info to Akram's answer.
You could use try some of the filters from G'mic (a "plugin pack" for the Gimp which has a lot more filters than just noise removal ones). Here's its website and download page.
For a tutorial: Noise reduction with G'Mic
. An excerpt:
Anisotropic Smoothing is the best solution for pure noise reduction, it can be found ...
I do have some experience with the particular calibration tool in question, and while it's hard to give a general answer to questions like "Is paper an ok diffuser?" (there are many kinds of paper), I'll share my experience.
Firstly, I feel a little differently about the importance of calibrating vignetting at different focus distances than what Torsten ...
I suspect that part of the problem is that until recently, cameras were fairly closed off "bespoke" embedded devices—there was no real money in releasing free firmware, and the systems were "unusual" enough that you'd have to dump the firmware out, do some pretty serious reverse engineering, and test per model.
In theory, even if a platform was closed off, ...
I figured it out! I noticed there were some extra files in .wine/drive_c/windows/system32/spool/drivers/color/, some of which I guessed were from my experimenting, but I wasn't sure, so on a whim I tried removing them all and restarting Lightroom, and then I saw a file being created called 26d6cc1d628462ebbe35d4d50d34c8bfa086b9c7.icm. So I closed Lightroom, ...
I think the biggest concern is that custom firmware could force a camera to operate outside of its normal operating limits, thus making it possible to break it with software.
There would be no way for the manufacturer to prove this occurred thus they would have to honor the warranty, despite the user abusing the camera (with software).
Why my RAW is noisier than Jpeg?
Because the JPEG created by your camera included the noise reduction contained in the camera's raw processing engine. When you work with the raw file in another application, none of the in-camera processing used to create the JPEG is used by your external raw processing application. It uses its own noise reduction algorithms ...
If this is in order to get a nice animation of the images, you can use Google Photos. Then, once they are in your library, select the images you want, click the big plus in upper right, and select Animation. A few seconds later, you have an animation of the aligned images.

I've been using GIMP for years and I'm fine with it. I've never found the lack of high bit depth an issue. In my experience this issue is exaggerated in importance. The UI works fine, and I think it's partly what you're used to and what works for you as a person. The only thing I wish it had were adjustment layers.
An extremely useful plug-in is G'MIC ( ...
Avidemux is a good tool for this purpose. Open source, free.
It is the easiest. Just open the first image from the folder in which you have the sequence. It automatically populates the rest for you! Then you have to export it as video.
Color management aims to reproduce the same color on different devices so that there is consistency through image capturing, editing and final output generation.
A good overview is available on Cambridge in Colour.
Accurate color in color management means the same color, not an improved or more beautiful color. To alter or improve your colors, you need to ...
The package RawTherapee, since version 4.0.9, will use Adobe .lcp profiles. Please see: http://rawtherapee.com/blog/rawtherapee-4.0.9-released
Support for Adobe LCP lens correction profiles
It is available in the Ubuntu repositories.
It doesn't require importing photos, and works right off of you file system. When you edit a photo it creates a file along side that photo that can contains the edit info, and leaves the photo untouched.
The Wavelet denoise GIMP Plugin might be interesting for you. See for example this video tutorial and Post processing on low light/fast shutter photo.
I think RawTherapee also has wavelet tools (I'm no expert, though), see http://scribble-jpc.blogspot.se/2015/03/first-view-wavelet-tool.html and http://scribble-jpc.blogspot.co.uk/2012/07/first-look-...
My own answer would be that the primary reason for disallowing it is that it would prevent sandbagging by the camera manufacturers. E.g. here are some software-only features in the latest generation of Canon cameras that could be available on any model rather than limited to higher-end products:
Built-in bulb timer
Frankly, freeloading off other folks' work makes it seem like you're just being cheap and lazy. You can take 360ºx180º panoramas with a smartphone and fisheye attachment if you know what you're doing, and using a plumbline to keep yourself at least close to rotating around a no-parallax point isn't that expensive. The defects aren't from your hardware/...
OK, will post as answer, thanks. Works perfectly for me too.
I passed over Lightroom for a similar catalog reason. Too much unwanted stuff between me and my images. I just use Photoshop, it is the same ACR module that is in Lightroom, editing works the same. Use its Bridge to open by pointing it to any folder your PC can see. Select one or many or all ...
Aftershot Pro is worth considering. It uses an optional catalog, so if you know where your files are, you do not need to use it. If we want powerful search, then you can opt in.
It supports RAW. It is quite fast too and has basic controls for photo editing as you ask. I am not a Mac user, so I have no idea what it looks like on a Mac nor if it matches ...
You can submit photos to free stock photo libraries. www.sxc.hu (changed to www.freeimages.com) was I think bought by iStockPhoto, but looks like the group might have been taken over by Getty Images. If you're happy for your images to be used without charging people, this could be a good way of getting your images seen
Have a look at Trovebox. It's a hosted service but you can use your own subdomain.
In addition to being 'skinnable' you can share using password protected albums or even create groups with signins.
As the other answerers have pointed out, GIMP misses certain features that you can find in photoshop. But then you are not limited to using only GIMP. I use the following free of charge programs:
dcraw allows you to have full access to your raw files, you can e.g. work with the raw data before any demosaicing is done. ...
Darktable (which you can download for OSX here) is probably the software that comes closest to what you are looking for. The workflow still has some rough edges, compared to Lightroom or Aperture, but quite usable especially if you are looking for a scripting interface.
