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 ...

You can use cross-platform open source software jhead, with the options jhead -autorot *.jpg Which losslessly rotates the images based on the embedded rotation flag (and removes that flag, of course.

First we rename all *.JPG files based on their creation date. Sometimes cameras change the file name or just ordering them is somehow not what we want. However, renaming them by the creation date always work: jhead -n%Y%m%d-%H%M%S *.JPG After that we put this list in a file: ls -1tr | grep -v files.txt > files.txt And then use mencoder to create an ...

Here is the process I use: cd ~/directory_with_raw_files ufraw-batch --out-type=tif --out-depth=8 --wb=camera --exposure=0.33 --black-point=auto *.NEF Of course, you will process CR2 files instead of NEF. I usually open just the first raw file to find acceptable parameters for ufraw-batch, such as exposure. Then install the stacking package: sudo apt-...

I assume you have a gradient in overall brightness due to unevben lighting. If that's the case, what you could do is to duplicate the layer with the image and apply the best correction to each part of the image on a different layer: curves for contrast, color balance or desaturate for white balancing. Then, using layer masks you can paint each region with ...

The issue you're going to have is two-fold. The X10's EXR sensor is not something other cameras have, save for a couple of Fuji cameras. The EXR sensor can do a lot of things with the available pixels in the sensor and that is why their RAW files are a little odd compared to those of say the X-Pro1 or 100 which use the X-Trans sensors. You'll potentially ...

I would look into hacking a GoPro camera/camcorder to use a continuous power source. The GoPro is very well suited to harsh environments, and already comes with a housing that could be utilized. Further, it is very reasonably priced. If you are serious about low light ability, the newest Hero3 Black Edition claims 2x better low light ability then the ...

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.

So I've decided to do the following: I'm going to buy a used Nikon D40 kit with the 18-55 lens off of eBay for about $200. To power it I'm going to use a $9 Nikon EP-5 power supply connector and a 18W 12v to 9v buck converter I found for $4. For communications, I'm going to try a $7 10m USB 2.0 Active Extension / Repeater Cable. I'm going to modify a PVC ...

This is a native software you could use: http://entangle-photo.org/ Edit: And this too: http://www.darktable.org/

Decoding the ini file is possible, but translating them exactly into darkroom/shotwell edits is going to be problematic. The image manipulation algorithms are different. Your best bet is to export high quality JPEGs (or if you have a lot of disk space you can use TIFFs) and keep the RAWs as an archive. This is the approach I have taken as I moved from ...

Since you have a D5300, the answer is clear — Darktable just added support for that camera in version 1.4.2, at which point it was listed as "experimental". Darktable 1.6 was released a month ago (December 2014), so upgrading to that should solve your issue. If it doesn't, I'd add your feedback (and a sample file?) to this issue tracker request: Feature #...

Every image format (JPEG, PNG, TIFF, etc.) that I know of can only represent rectangular images. This means that unless you define your own image format, this simply cannot be done. The only thing you can do is to work with transparency. Even though the image itself will still be rectangular, if only a circular portion of it is opaque, it will look like a ...

In the past when attempting to install Photoshop on Linux, I've had little success. In reality there is probably no foolproof solution that will allow Photoshop to run without any problems, though there may be a few more things you can try: Install using PlayOnLinux PlayOnLinux is a program similar to Wine, though is designed primarily to run Windows games ...

Most every DSLR/SLT/DSLM - certainly major brands like Canon, Nikon, Sony, Pentax - saves to SD or CF cards in a standard format, and additionally supports USB mass storage protocol, you DO NOT NEED any drivers installed on a host computer to be able to access the images taken. Tethering, or upgrading camera firmware, might indeed prove difficult from a ...

It looks like currently you can't just plug it in and have Shotwell work out-of-the-box, but if you don't mind a little work, you can mount the camera via "PTP" mode and then import the images from the filesystem. See this blog entry from someone who did this on FreeBSD; the Linux situation will be similar. Probably eventually the software will gain direct ...

A reasonable answer to this would be "it depends" (another perspective is to "battle a little against the idea of objective metrics") I'd recommend consulting this chart to determine how long you should spend trying to figure out a quicker way if 'quickness' is what you are looking for. However if you decide to approach this as an exercize in ...

Exiftool reads many raw formats. You can use a command similar to this one to rename your photo files : exiftool '-filename<CreateDate' -d %y%m%d_%H%M%S%%-c.%%le -r -ext cr2 /path/to/pictures Change cr2 to whatever your raw extension is, and /path/to/pictures to the desired folder. Once renamed, you can sort them by name. There are more examples ...

OSX-only options G3 / F3 Godox/Flashpoint has released an OSX version of the G3/F3 updater. However, at this time, it only supports updates for the following devices: V1 for Pentax TT350-P and Xpro-P AD400 Pro Flashpoint R2 Pro II For all other devices, or from Linux, however there are a few different ways you can do this, if you don't want to, say, ...

The Fuji X-E1 works with Ubuntu Precise Pangolin (12.04 LTS) out of the box. The camera just needs to be connected via the provided USB-cable. Ubuntu will recognize the camera as PTP-camera, and open either Nautilus (file manager) or Shotwell (photo manager) at the user's choice. Both applications are pre-installed by default. I noticed however, that ...

Yes, using the collect images module on the left. Select 'history' from the left dropdown menu then double-click on 'altered' to show only those images which have been modified. Try Darktable's user manual page for a fuller explanation. Additionally you can stack rules so you can narrow down searches, eg, by searching by a particular roll or folder and ...

There isn't one, overall. I don't think anything focuses on this specifically. Any distro can work just fine, and I suggest picking one that you like in general and the photography apps will follow. That said, there are two considerations that are probably worth... considering. First, unless you plan to find and compile various software yourself, you want ...

I'll tell you right away that there is no chance for me to answer without being very technical. Since you're looking for an open source solution it cuts away all of the commonly used programs and leaves us with a bunch of programs that require more from the user. The advanced part has nothing to do with photography though. The technicalities lies in ...

LibRaw supports this format (current development trunk). So, you may use any LibRaw-based software (digiKam or so), but you'll need to update/recompile LibRaw and software that using it.

RawTherapee supports Canon PowerShot G16 starting RawTherapee version 4.2.

That is the result of the raw processing program not having the correct profile for the said camera. Getting an updated version should resolve your problem. The list of cameras supported by RawTherapee, together with the version number since, can be found at RawPedia.

Just solved the issue by chance - I used exfatlabel to name my card and voilá it was auto-detected and works fine under Linux and in my 6d:)

There are actually three possibilities here. First and most likely, I think, make sure you have the latest colorhug firmware. Run colorhug-flash to check. I have one of the very first colorhugs, and this red cast was common, but sometime in the last year a new firmware reduced this significantly. Second, there's actually the possibility that it's not as ...

As written in the comments (see http://rawtherapee.com/forum/viewtopic.php?f=3&t=5406) the issue is not intrinsic to 12 bits, but it is caused by a wrong interpretation of the RAW data by dcraw (the common RAW decoder used in most Linux software). The link above provides a temporary solution (set black point to -450) while waiting for an updated dcraw (...

The command line program jpegtran can losslessly rotate JPEGs on Linux. From the command line: jpegtran -rotate 90 MyJpeg.jpg > MyJpegRotated.jpg If you don't have jpegtran program installed, you can install it in Ubuntu with: sudo aptitude install libjpeg-progs A similar tool is exiftran, which can determine orientation from the EXIF tags: exiftran ...
