    Re: Stacking photoshop layers concept vs using ND filter

    Recently I have made some good shots, making many shots of the same frame and now have a problem when it came to a post processing. I guess as some of you already experienced that, hopefully could help me now ☺ In my photoshop cc 2015 stacking mode is grayed out. I did everything correctly so far with layers and so on... I read about issue on the Internet and some people have experienced that but with photoshop cs6 for example and it is said something like it's an a bug or something related to Adobe engineering. Is there any solution to this issue, or maybe some other program that could allow me to stack photos in order to get longer exposure like photo with reduced noise as well?

    Search the net for free stacking software. Download and install it and see if it accepts your image files. Some software can use RAW files while others need JPEG of TIFF. In case it accepts TIFF, then export your RAW files as 16 bit TIFF for better DR.

    I will try it, definitely. I was preoccupied with photoshop surprised with it's malfunction in stacking.

    Could one increase sharpness by stacking images from a stationary shot? I saw a comment on an article about sharpness. Here is the comment:

    "If the target has a lot of air between you and it and it is stationary, shooting ten or more exposures and then digitally stacking them produces a dramatic improvement in clarity and sharpness. This is a routine procedure in astrophotography. The image clarity will increase with the square root of the number of exposures stacked. Stacking also tends to eliminate the grain noise from the image as the noise is random and tends to cancel out with multiple images. The whole purpose in stacking is to increase the signal to noise ratio."

    I would think the variations over the 10 photos would increase blur, not sharpness. How do you stack to increase sharpness?

    As far as I could understand when staking for sharpness, the software rejects those parts of the image that are not there in every frame, effectively getting rid of the "halo" at the edges.

    For example if you take 10 shots of an object, say a tree and there is slight wind then there will be slight shift image to image creating a blur if you average the frames. The software will get rid of that blur.
