Originally posted by Liney OK folks, a couple of questions for you, all based on a K3:
I had a play with the multi-exposure and interval composite modes, and set both to 3 images just to see what happened. With multi-exposure selected it took three images and displayed one, so how do I know that it didn't just take three images and not combine them? Admittedly I was set up on a tripod and had taken a couple of images before, so I had several images of the same thing which may just be confusing me.
Which leads me to the second question, shooting interval composite. Again I set it up for three images, and it appeared to take all three and only display one. However when i read the manual (as a bloke I find this disturbing..} I noted that it says "When [save process] is set to (box ticked icon} a new folder is created and the composite image is saved there". I assume that this is a seperate folder on the SD card, if that is the case why doesn't the multi-exposure do the same?
I'll need to go back and play some more, but does this sound right to you?
First, to really see what these modes do, it's best to shoot a non-stationary scene. If nothing moves, then the only difference between a normal single shot image and a composite shot is the composite shot will have less noise (which can be a huge plus if you want to shoot at very high ISO -- 32 "averaged" shots at ISO 51200 is like one shot at ISO 1600).
Both multi-exposure and interval composite modes merge some number of collected shots together using the compositing mode you selected ("average," "additive," or "bright") into a single shot. The only difference between the two modes is that:
1) multi-exposure takes one shot per shutter button press. This lets you change the composition, framing , or timing for each frame. It's great for controlled multi-exposure images where you overlay different objects and scenes on to each other.
2) interval composite starts shooting all the shots after a single shutter button press using the interval settings (which control the timing of the first shot and the delay between shots). It's great for timelapse photography or simulating ultra-long shutter times without an ND filter.
"Save Process" collects and composites the shots as it goes (just like the normal unsaved mode) but also saves the interim results. Thus, the folder it creates has the same number of files as there are numbers of shots. The first file contains the first shot, a second file contains the composite of the first 2 shots, a third file contains the composite of the first 3 shots, and so on up to whatever number of shots you wanted. "Save Process" is great if you aren't sure how many shots you'll need to get the effect you want or some undesirable change might happen in the scene. Note that save process does NOT save the individual uncomposited shots, only the composite. There's no clean way to get the individual shots -- if you want the individual shots, then use interval mode (not interval composite) and do your own post-processing to stack the images.
