Re: hdr with raspistill/raspiyuv

Why do you need 15fps? Isn't it too much for a time lapse? The result will only be twice as fast as real time. v4l2-ctl is capturing video, right? I think you should capture stills and merge them in post production.

Smartphone or m12 lens?

Hi!

I wonder what produces a better image. Adding a cheap wide-angle or fisheye smartphone lens to the original lens or replacing the original lens with a cheap wide-angle or fisheye m12-lens.

What do you think?

Re: hdr with raspistill/raspiyuv

OK, I've found the -ss parameter ;) But what is the possible range? In the documentation i've read 0,33s and in the forum 6s for the longest exposure. What is the correct value? And what is the shortest exposure possible?

hdr with raspistill/raspiyuv

Is it possible to capture e.g. 7 pictures witch are 2 stops apart from each other to use to create hdr-images? As far as I've seen there is no manual exposure control an the -ev parameter is limited to -3 and +3 stops.

Re: Compiling code written for x86-CPUs

<t>Hi!<br/> I wonder If code which is initially written for x86-CPUs simply can be compiled on the Pi and the program will run. Or does the code need to be optimised for the ARM architecture?<br/> <br/> I''m quite experienced in programming C++/C# on Windows and Linux machines, but never got in touc...
