Alignment of multiple images taken from the same point
If you are not making a panorama, but just aligning an image stack for focus stacking, exposure fusion or HDR, then align_image_stack from Hugin project is one of the simple yet very useful tools. Hugin is a multiplatform collection of tools that is available for Windows, Mac OS, and Linux.
How does one delete rejected photos from within Darktable
Use 'Delete' button (Lightroom mode, right panel, 'Selected Image(s)' module): it "physically deletes" selected images from disk. It helps to display only previously rejected images by setting 'View' filter (Lightroom mode, top panel) to 'rejected only'.
For faster use, you can associate a hotkey ...
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 ...
I have one. You're right — it's a good value for the money, and there's basically no catch except that if you're running under Mac or Windows you'll need to know a little more about what you're doing than you might if you just bought one of the big-name devices.
That's because there's only software for Linux. If you are using Linux (any modern distribution),...
Canon wins hands down in this regard. Many of Canon's compacts can run CHDK (sources), which exposes otherwise unavailable functionalities. The more recent DSLRs can run Magic Lantern (sources). Magic Lantern adds huge amounts of functionality, including the ability to shoot timelapse and HDR within the camera, and a built-in intervalometer.
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 ...
As you can see right on the main CHDK wiki - "Temporary – No permanent changes are made to the camera." You also can find very detailed information in the FAQ here.
Basically - Yes you are hacking your camera. So things can happen that the original manufacturer did not intend(if this wasn't true, you wouldn't want it anyways). But the chances of any ...
This is a non technical answer. I just want to describe my experiences using both.
I use Darktable (version 1.2) on Ubuntu 12.10 and on OSX and the RAW handling is pretty slow, but it handles JPEG processing swiftly and with no processing time. It can get flustered and will often bomb out if you do massive imports of JPEGs. I shoot JPEG for ...
There is a hacked firmware extension for Canon called CHDK, which is pretty extensive and well-documented. A lot of the features are in-camera I think, but there are UBASIC scripts for doing intervalometer type stuff. There are a lot of CHDK-related questions and answer on this site.
Nikon has an official SDK which allows you to:
I would say in terms of order
Sony has a repo where you can have access to the operating system, if doing embedded development is your kind of thing. You can access their current repository here.
Canon because of the Magic Lantern work and the fact that they do publish some form of API to work with DryOS.
If you were a end user who had no ...
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))
Ha. Nobody mentioned free windows alternatives.
I've been using windows live movie maker with good results. It is as simple as dragging your pictures into the timeline, selecting them, setting a time for each (24 fps is around 0,04 seconds per picture) and exporting :)
(It auto-adds black vertical bars to your 3:2 or 4:3 aspect ratio pictures if you export ...
I'm not sure about GIMP, I use Lightroom 4 and there is this wonderful plugin Noiseware 5. I used it myself and I got good results. Some report Noise Ninja to be a good tool too but I didn't try it myself.
I'm sure that you can do this in GIMP without plugins, a quick googling results that maybe helpful:
Reduce Noise in GIMP
DNG, with the XMP sidecar, can likely serve as a portable format.
However, you wish to have the file rendered on a browser with the edits. The problem is that when viewing a RAW file, there is a JPEG image embedded in the RAW (and DNG), that is used for image preview. This is what browsers and OSs use to create thumbnails etc of RAW files. Therefore, even ...
There are literally thousands of "standards" used in digital photography, but few address what you seem to be asking: open standard hardware, os/file systems, etc. ASA/ISO film speed is a standard, as are APS-C and 35mm sensor sizes.
Sadly, all of the consumer oriented brands (Nikon, Canon, Sony, Olympus, etc.) are totally locked into a philosophy of ...
For Windows, you can use VirtualDub. It is free and open source.
To create a timelapse, you need all of your photos numbered in order, without any gaps in the sequence. Then just go to File > Open, and pick the first image. VirtualDub will then load all of the images.
To set the frame rate, go to Video menu > Frame rate. You can also add filters if you ...
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).
At least Panasonic cameras store lens correction information in the raw files. Some preliminary results of reverse-engineering the relevant exif fields can be found on http://syscall.eu/#pana.
The distortion correction information is stored in the 0x119 tag, and consists of 16 16-bit integers, the meaning of which is decoded in the linked post. The ...
I've had no problems with CHDK on a A430 doing timelapses over a day or two. I've also used it to enable raw capture.
I would concur with cmason's use of the phrase "alternate firmware". It's still firmware, it just doesn't replace the factory firmware. There are warnings on the CHDK website indicating that CHDK may make it possible for you to request ...
CHDK is alternate firmware that is loaded on your SD card. It does not alter the factory firmware at all. When you start up your camera it loads this alternate firmware. When you are done with it, or don't care for it, simply put in an empty SD card and turn off/on your camera and it loads the factory firmware, just the way you left it.
I like open source too - but you are looking for the wrong thing.
A camera that supports the longest list of open standards is still not "open" - the fact that the camera uses AA batteries or a 4/3 mount (to use some of your examples) doesn't let you extend it or modify it's behavior in any meaningful way (except by buying accessories, obviously, and even ...
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 ...
Your two main choices are Gallery 2 and Zenphoto. Both offer plugins that offer shopping cart functionality. Gallery has more sophisticated choices, but unfortunately, the Gallery developers have a habit of throwing everything out and starting again — Gallery 2 is a total rewrite of Gallery 1, and Gallery 3 is another total rewrite.
And, the latest version ...
Piwigo is an open-source photo gallery you can install to a subdomain of your site. There are many themes and extensions, access control by password, and editable CSS if you really want to make heavy customisations. I use it on my site and I can definitely recommend it.
If you want to delete all "reject" photos, change view to "rejected only". Then you can select all by "ctrl-a".
Simply hit delete key to delete from the collection.
If you wanna delete from the disk, you need to open "selected images", and the select "delete". Of course, say "Yas".
I setup shotcut to "ctrl-delete" and it's work very well for me.
How about GIMP? It should be there under filters. In 2.8 it is the IWarp filter under the Distort section. There is also a Warp filter under the Map section, depending on which type you are looking for.
Update: If you are simply looking for a more user friendly implementation, then you are unlikely to find anything that matches Photoshop for less than ...
Usually, the blue channel has more noise than the others. So an old trick is applying a slight blur to the blue channel might help.
That said, noise reduction software like Noiseware and Noise Ninja are so far advanced beyond this old trick that you might find it worth your time and money to look into a more automated solution.
One key difference is not in the product itself, but its development. There are about two developers working on Gimp, and as a result, new features take a long time to be production ready. They 16-bit GEGL engine has been in progress for a couple of years and is not yet released.
I don't think it is fair to say that the Gimp UI is terrible, but it is very ...
I'm doing it my way in GIMP - I take "Free select tool", select the part I want to modify. Then I feather the edges of the selection by 30-100px depending on the size of selection (most often I go for 50px), then I copy the feathered selection and past it as a new layer. This way I can do any adjustments to this particular bit and the rest of the image will ...
