RE: [APML] CCD experiences



Tony, its good to have you back into film again, you are a master of the chemical technology bar none.  I agree with many of your points on the time spent on obtaining decent CCD images, all for a image size that is painfully small. Thats why I built an observatory just for the schmidt camera - to take high resolution wide field film images and have huge file sizes for sharp enlargements.  Welcome back!

Hello,
 
    As some of you might have guessed from my message to Bobby, I have parted with CCD completely. What at first seemed like an amazing medium turned out to be something quite a bit different... my greatest disappointment has been with the "noise" issues... it's not enough to take good RGB exposures... after that comes a lot of dark frame exposures and flat fields... to get an image like Rob Gendler's one must go to unbelievable lengths. I also don't have the steadiness of seeing that a CCD necessitates, but I do have dark skies. So I am returning to film, only this time I am going to concentrate on slide films... I think they are sharper than negative films.
Philip posted a very good summation of CCD vs. film quite a few months ago... I would like to add that although CCD is in essence a tricolor process, the noise issues make it a different experience. Not much else to say about this... I wish I knew back then what I know now...
 
    Have a good one,
 
        Tony
