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 ...
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.
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 events ...
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 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.
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 ...
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))
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.
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 ...
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 ...
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 ...
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 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 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).
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, ...
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 ...
Try Time-Lapse Tool Software for Windows. It provides lot of featuries such as:
Zooming and panning your frames
Add soundtrack to movie
Render your movie to different video formats or publish to YouTube
Easy to apply image effects
Free Community Edition available
(Note: I am affilated with Timelapse Tool.)
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 ( ...
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-...
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.
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 ...
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.
Here is a link to a great hack of controlling a Canon 5D mark 2 with a Raspberry PI. It puts the R-PI in a battery/grip so it looks normal.
My guess is that neither Canon nor Nikon want to encourage these hacks, but I love them.
