Hello Jean-Pierre, I am very glad to hear that it works. Could you improve on the long"ish" startup-time of gphoto2 you mentioned ? What came also in my mind is that the gphoto2 makers, at some point, made start-up of their application faster. Unfortunately, I do no tknow right now with which versio...

Hello jplorge, Sorry for not replying earlier, i was a bit head under... First, for the disagreement of the settings for the exposure times: I cannot confirm right now, but try to set the index umber, instead of the exposure time directly. An Example; If all were well, without the bug i mentioned in...

- About 'p'% my most fair answer is "I don't know". I suspect I would accept 10% for dark values and much less (2% ?) for bright values but... (on histograms how tall is a bar is more than often somewhat adjusted and should not be used to guess those threshold values - size of out of bounds regions...

Ok. I think I will first try to implement a simple algo, using what you suggested: reshoot as long as 'p' % of the pixels are over level 'l', increasing by 'e' EV each new shot. Same for the opposite. p, l and e will be user-defined parameters. What possible range do you suggest for these params? M...

No problem, you can use this code: it is open-source. The only restriction is to publish your modifications (if you want to publish anything) under the same free license (you can switch to GPL if you want, CeCILL is fully compatible). Hello Frederic, I never meant to want to change the license in a...

About analysing the RAW, I don't think it is mandatory: you don't need a very important accuracy. Don't forget that the way how over-exposed pixels are spread arround the image also very important: small white dots (little reflects) are not a problem: a large area is. But doing such analyse will ta...

@ claude Thanks for adding me to the list, I will add a few more infos there. As well, I will share my 2 cents on gphoto2 on the wiki... might take a day or two, but will do... Gunnar EDIT: Where in the wiki do you think the "gphoto2" page should live ? Would that belong to the user guide (in the tr...

Hello Frederic, Thanks very much for providing the code. I see you are analyzing the thumbnail image, which of course is much quicker as analyzing the whole image. It has the added advantage that you can also analyze RAW images, since they include a thumbnail as well. One assumption that has to be v...

I have to say that I'm not yet decided if I will implement timelapse in Papywizard, or as a separate application (with large parts of code shared with Papywizard)... And as I already said to some of you, I'll be very busy in the next months/years, because I will build my new house! So, Papywizard p...
