Raspistill signal change shutterspeed

Hi there! When having raspistill in signal- and burst-mode is it possible to change the shutterspeed between captures ie by sending a special signal to the raspistill-process? Or is there another way to capture two images in a very short time (<1s for both images) in full resolution with changed shu...

Re: dcraw support for raw images

Can you offer your compiled dcraw? When I try to compile it on my rpi or ubuntu-machine I get this error (tail): /tmp/cc2bjWu2.o: In function `main': dcraw.c:(.text.startup+0x0): multiple definition of `main' /tmp/cc3Twzz8.o:dcraw.c:(.text.startup+0x0): first defined here /tmp/cc2bjWu2.o:(.rodata+0x...

Re: RAW output information

Imatest result from bealecorner.org:

I took your last Raw-Image you did with your M12 lens and ran it through Imatest. For MTF-calculation I took one border on the right side of your chart.
Enojy!

Re: RAW output information

Bernhard,

did you find a way to get your raspiraw-version running on the rpi?
It could be really useful...

thanks!

Re: RAW output information

Hi, the new raspi_dng-binary works on my rpi, thanks for that. As a student I was able to get my hands on a Imatest-Master-License and at my lab we've also got a spectrophotometer with which I can measure Lab and XYZ-values. What I'd like to know is how can I refine the rgb-matrix with Imatest as I ...

Re: RAW output information

sorry, you're absolutely right. I tried to compile the newer version on my rpi b+. The Illes-version compiled like a charm but the newer did not work at the very end. It seemed a tiff-library was missing. I'll get the compile-log later, I don't have it right now. What I try to do is using Imatest, o...
