First off: Even Andrew Kramer, king of After Effects, simply goes through all blending modes to find an appealing effect. So playing with them is a really good option. There are common uses for some blending modes, though: Screen and Add both make dark parts of the image transparent. (That is, the color from the layers below will show through dark parts.) ...

I didn't have enough "reputation" to address some of these answers as comments. AJ Henderson is wrong, 30 1s exposures will (for the most part) be identical to 1 30s exposure. If it shows up in a 30s exposure, then stacking 30 1s exposures will also show it. I am actually the author of the article that Trengot linked (thanks!). In fact, unless you are ...

Fundamentally you're capturing the same amount of light in either case so the results should be the same. Practically, there are 2 differences between stacking 30 one second exposures and shooting one 30 second exposure. The first is the light lost between each one second exposure after the shutter closes before it reopens for the next exposure. This can ...

No, 30 one second exposures is not equivalent to a single 30 second exposure. You do gain a lot of information from doing 30 1 second exposures, but you are not able to detect anything that is too faint (which might have shown up on a 30 second exposure, but still registers as 0 on the 1 second exposures). It is a good technique to avoid noise, but does ...

i don't think it is possible. amount of light on every photo is the same, it means no additional information in details you can add, so it's like you have only one photo

Yes it is possible. Put all images as layers and choose Add to on every layer in Photoshop. For night sky images, there is a software called deepskystacker. DeepSkyStacker is a freeware for astrophotographers that simplifies all the pre-processing steps of deep sky pictures. http://deepskystacker.free.fr/english/index.html This image is stacked from 4 ...

This explains how to merge multiple short exposures to mimic the effect of a longer exposure. It's aimed at emulating ND filter photos but the principal should be the same. The basic premise is to take multiple shorter shots and then use a tool like Hugin to align and ImageMagick to convert them into in a single image. The result is effectively the same as ...
