Group selected by time is extremely valuable for doing AEB shoots. When I use this feature however it usually groups my single AEB set into more than one group and I have to manually combine them. From the documentation it looks like the time difference it looks for is 2 seconds, and this is hard coded and not user adjustable. Can this tolerance be added as a user adjustable setting so I can pick a tolerance which seems to work for my equipment/workflow? extra info: DJI Air 2S drone using 5 exposure AEB, it captures all images automatically with one press of the shutter button and does so as quickly as possible. It typically takes more than 2 seconds to capture all 5 images so the Digikam feature doesn't work completely correctly here. Using my mirrorless (R5 C) with AEB I need to press the shutter button manually for each of the images in the bracketed set, this also will likely take longer than 2 seconds frequently. Thanks! I appreciate everything the Digikam team does!
How do you envision the selection? Should there be a setting in the setup? Or should there be a submenu with "Time 1 second...etc. until...Time: 10 seconds". Would 10 seconds be sufficient as a maximum time? Maik
Thanks so much for considering this! I was watching a video to learn more about this process when I saw this feature being used in lightroom. In lightroom when you group by time it actually gives the user a pop up asking them to specify what the tolerance should be before it proceeds with the grouping. In that particular video the photographer specified 10 seconds, therefore any picture taken within 10 seconds of the first was considered part of the same AEB set. I guess in a perfect world I'd love to see a setting in the settings window allowing me to specify the tolerance for the time grouping with a checkbox option to prompt me each time in case I need to change it on a case by case basis. maybe I could find a value that would work great for everything and just set it and avoid the need for an extra dialog, or maybe I would want to fine tune it each time. As for a max allowed tolerance, 10 seconds would probably work for almost all cases, what I wonder is though: when I use auto bracketing on my camera (Canon, I don't know if other brands do this also) it doesn't take all of the exposures automatically like the drone does, all it does is automatically set the EV compensation for each one. so if I set it for 3 pictures, +- 2 stops for example, I take the picture at the exposure I set, then the camera indicates its in AEB mode, sets the EV compensation to -2, waits for me to take the picture, then sets it to +2, waits for me, then goes back to normal. So I have to take all the pictures by hand. If I'm not quick at pushing the shutter button, there could be several seconds between pictures. if I were trying to combine AEB with a flash for example and needed to allow it time to recharge, or I had an extreme dynamic range situation where the bright picture needed to be a long exposure, there might end up being more than 10 seconds between the pictures. I was thinking in some scenarios I might want to set it as high as 30 or 60 seconds to make sure to capture everything. whereas in other scenarios that would be way too much and would end up accidentally grouping pictures from other sets. That's why I was thinking it might be something that could change frequently depending on the situation. 5 seconds or so would probably be plenty for a drone AEB shot where it automatically takes all 3 or all 5 pictures as quickly as it can. whereas 10, 20, 30+ seconds might be needed for other scenarios with a more manual AEB process. Speaking of which, what is the interval that it is considering here? When doing AEB every camera I have used always takes the normal 0EV picture first, so when it is considering this, will it be looking at the first picture it comes across, then grouping everything within the set number of seconds into a group? meaning check interval of picture 1->2 is it within? yes add to group. then check picture 1->3 interval, within? etc. then when it encounters the first picture outside of that tolerance, does it then start over with that next picture being picture 1 of the following group? or does it go picture by picture, like check 1->2, if within add to group, then check 2->3 if within add to the group check 3->4 etc. I think the first scenario would be more reliable for combining AEB pictures, whereas the second would be better for combining all pictures in a time lapse or something like that into a group.
