Re: [darktable-user] Merging a small darktable library with a larger one on a different PC
My understanding is that all that is needed is the raw file (CR2 for me) and the sidecar (XML). These should keep all the history and tags. I have removed images from collections a number of times and then re import them. I don't really have 2 machines running DT but I don't know how can it be different from remove and re import...If there are preset changes - depending how big they are. You can actually make a style and export it then import it on the second instance. Other approaches may be to copy .config/darktable from one location to another. But this is not really merging - it is more of getting all configurations and copying it to a second machine. The pictures will be missing of course - so DT will display sculls - and these can be just removed from the collection. Hope this helps.

darktable's user-interface focuses on efficiency and on avoiding visual
distraction ("it's all about the image"). It takes some time to get used
to it, and reading at least part of the manual is really necessary, but
once you'll get used, you will probably love it and start thinking that
waisting some pixels for a scrollbar would be a shame ;-).

Re: [darktable-user] Colour profiles
Graham White writes: > I have a problem understanding the various options for selecting a > colour profile for printing. There seem to be three places where you can > set this, namely: And there are indeed 3 things you may want to do with profiles: 1) Make sure images are displayed properly on your screen. This is the "display profile" and is typically obtained by calibrating your screen. It's independant from your printer, obviously. 2) Make sure colors are rendered properly when printing. If I understand correctly, this is done in two steps: first export the picture to a large colorspace (as much as possible larger than your printer's), and then correct the colors while sending the image to the printer. You would distinguish both steps if you were sending the file to someone else: you'd do the export and the other end would do the printer-specific stuff. These are the two profiles listed in the print dialog: https://www.darktable.org/usermanual/ch07s02.html.php https://www.darktable.org/usermanual/ch07s02s03.html.php 3) Softproof: get the best possible approximation on screen of what the final printout will look like. In other words, replace colors that your screen can render but that your printer can't with a color that your printer will be able to print. You can customize this with the softproof button (right-click for details) in the darkroom view. This is not strictly needed to get a good print, but you probably want this if you have you printer's profile.

Re: [darktable-user] HDR
Hi, Nikon's D-lighting is actually what darktable calls "shadows and highlights". Just one shot, reduce the exposure on highlights and increase it in shadows when generating the in-camera JPG. Michael: if you want to do "HDR" as in "image with a dynamic range too large to fit in a normal jpeg but small enought to be captured by the camera's sensor", then darktable has all you need. Use any combination of shadows and highlights, global tonemap, tone mapping. If you mean "image with a dynamic range too large for the camera's sensor", then you have to shoot several pictures using exposure compensation in your camera (or exposure bracketing) to take typically one -2 EV, +0 EV, +2 EV or so. Then darktable can combine several RAW files into one (lighttable, group "selected images", "create HDR"). The algorithm it uses is pretty basic and cannot do image alignment, hence you need a (good) tripod. You can also use Luminance HDR to generate an HDR (i.e. a single image that combines several shots, but has a dynamic range too large and shoud be tonemaped to be viewed properly) image and import it into darktable to do the rest of the processing.

Re: [darktable-user] Collect images
Hello, Within the lighttable, expand the Collection filters tab, then select Color label, select the color to exclude and then the operator Exclude pictures. Repeat this for every color you want to exclude. Then, for each roll you want to see the pictures, select Roll, select the roll name and finally select the operator Include pictures. Thre must be some other / easier way, but that's how I would do. BTW, can someone confirm whether there is or not an empty line between each line in my message ?
