Title: Did I ruin my lights somehow???
Post by: ammcdavid on 2010 September 12 11:40:43
Hey all,
Just a question.  As I had said previously, I had some lights I had taken a few weeks ago with some data in them (wide field constellation pics).  They are still in the cr2 format from the camera and when I originally opened them, the pics appeared black and I used the STF with Track View enabled to shift the image so I could see it on the screen to verify there was some usable data there. 

A few days ago, I opened the images again to finish preprocessing them and now they are a "black cherry" color and when I use STF, there appears to be no data at all......the screen eventually turns white.  What the hell did I do to these images to cause this?  I am truly perplexed because other than using STF, I have done nothing to the images.....at least not that I am aware of.  Am I in some type of newbie PI purgatory  ???

Any guidance is appreciated and sorry to waste your folks' time with what is probably something stupid I am doing or have done.

Screenshots and example files may help folks determine what's going on.

Do I just imbed a screenshot in the thread or do I post images in the Gallery?  All forums seem to have differing rules.  Well, I will just go ahead and insert screenshots.....

Screenshot1: Light file selected to open....all of these in the 400's are lights.

The next post will have the following steps since I am limited to 192kb per post.....

.......Screenshot 3:  Actual Image File (note black cherry color...used to be black the first time I opened it)  Only used STF on it to "see" the data on my computer screen...no other processing.  I can add that I opened one of my flats yesterday and it too was the black cherry color but it doesn't contain any "data" except a flat white field so stretching it doesn't yield any detail.

.....Screenshot 4:  Same image file stretched.....no data showing up.
