Please pardon the noob question...I'm a relative novice to photography, but am practicing a lot and I can see improvement in my photos as time has gone by. Currently shooting a Nikon D3300 with the 18-55mm and 55-200 kit lens, also have a Nikkor 35mm f/1.8 as well.
That said, I know there are some limitations due to the camera and the lenses, but I figure if I learn my lessons well on this basic equipment, when I move up to something else, I'll have some of the "primary bases" already covered.
I switched to back button focusing recently, and after a bit of a learning curve, I like it much better than half press / full press on the shutter release. I'm also using LiveView a lot more than the viewfinder, where I'd normally be using the paltry 11 focus points on the D3300.
Photo stacking...I get the overall concept and the process of how to combine those images in Photoshop. The questions I have are in the set-up for actually TAKING the multiple photographs. Lots of vids on Youtube, etc. but none of them really address the "nuts and bolts" of what I'm about the ask.
So we'll say I'm on a tripod, VR is off and using a wired remote release to try and cut down on any camera movement. I'm shooting Aperture Priority, have framed the picture I want to take and I'm in LiveView.
*So is it just a (simple) matter of moving the "focus square" displayed in LiveView around the screen (red box, which turns green when in focus)?
*I'm assuming (dangerous, I know) that I would want to move focus from the back of the camera (closet focal point) and then on various points left/right/forward out to the far edge of the framed image?
*Any suggestion on how many shots should be taken? I know it will vary on many factors including the overall scene itself (open field with a mountain range in the background vs. a waterfall through the trees, etc.) but just looking for some general guidelines.
If that's the overall process, I think I get it...but my attempt at an explanation seems pretty simple, so seeking wisdom from the more experienced among ye...
Cheers!
