Yes - of course you need to have them scanned, then it is all the same. If you want to stack real negatives, you need to talk to the legends: Tony Hallas and Jerry Lodriguss.

>>Registar is reckoned the best and easiest but it is expensive

 

I know, I have tried the demo version and you can add and/or average

the images.

 

I understand that most people stack and average two or more images

to improve the SNR.

 

What I wanted to know is if anybody is stacking and adding several film images

(e.g. 4 or 5 ten minute set) to get deeper. This seems to be routinely done with CCDs.
