Hi guys.
Thought I'd put a question out there in the small hope someone might have an answer.
I've been concentrating on RGB planetary imaging with the DMK 21AF04 mono firewire cam and Astronomik Type 2 filters.
I use K3CCDTools capture software to acquire my colour frames. I then run each AVI through VirtualDub to convert to BMPs, then crop and centre in ppmcentre, then into Registax for some gentle wavelet processing and save as 16-bit TIFFS, then into Photoshop 7 where I convert to Greyscale, convert to 8-bit, merge channels.
I'm noticing that my initial merged image looks to have a very strong red cast, which strikes me as odd since I stack the same number of red, green and blue frames into each channel.
What's really got me puzzled is how hard I'm finding this to correct in PS. I've tried a number of different approaches in PS...but I always end up with unnatural looking colour.
Any ideas what might be causing this? Is there something I should be paying closer attention to at capture time? I usually just work straight off a greyscale histogram in ICCapture and try to get the same for each channel. Should I be using individual colour histograms...and are there such things in IC Capture which you fire up during capture?
Am I doing something wrong in Photoshop? Maybe I need to match my Photoshop workspace settings to the colour profile of the camera? Does the camera have a colour profile, given its a monochrome chip?
I've got some more experimenting to do and will report back with any findings or breakthroughs if I make them
Just thought I'd toss it out there.
