In theory, you can stack as many photos as you like. In practice, the more photos you have, the more likely software is going to be confused by something in the image and require some touch up work on your part. If you need 20 images to get the DOF you want, then go for it, but always do it in the least amount of images possible. You can still take 100 images when you only need 10, but delete the ones that don't help if the stack comes out poorly.
Taking the exact same image twice, equivalent to just putting the same copy of an image in the stack twice, is useless. You can take multiple photos of the same scene and average them together to reduce the amount of signal and spacial independent noise. but this won't help much in situations where you control the lighting like macro, and is most commonly used in astrophotography where the signal to noise ratio is small.
Thanks for the explanation.
That's what I noticed about my software, which is P.S 5 I think, and the computer I am using. It's a pretty fast computer, but at the same time it take's a long time if I add more then 15 photo's. a lot of time's I have to redo it, especially if I am surfing the net or playing video's while waiting.
Some of the turn's I do when focusing from near to far are 1/64th of a turn, which I'm sure does nothing, at least from what I see just before taking the pic.
I'm guessing around 1/32th of a turn should do. since the focusing ring doeas arounf a little less then 1/2 a turn.
About bridge, I use bridge to review my photo's in a stack before sending it to P.S to image stack.
all the time so far I do leave every image there, even thou I know 1/4 is not needed. I see that there is a way to use the magnify glass option, is there away to spot the focus line's?
How does focusing work? are there thin horizontal line's, that stretch from left to right?
It's really hard to tell the focusing lines if they are lines of the subject and background.
would using the magnifier glass help?
signal and spacial independent noise
Does this have to do with Iso?
Thanks for your help.
