Hello Developers,
I just want to share my first opencl experiences with you.
The positiv things to start with:
I have a core i7-2600k. I used to run it with onboard graphics (HD3000). With
this setup I get a JPG export speed of ca. 1.5 pictures per minute.
Today I got a Geforce GTX750TI. With

pictures you sent me.
the problem is still that the brightest exposure has a lot more sun than
the other images, so there are some unexpecte
