[RWebb]

Just turn the dial to "A" - then crank the aperture to f/16 - use a dial or on the lense - it should show up in the viewfinder

let the camera pick the ISO

the camera will also pic a shutter speed - for a decent distance, it should be 1/100 or so

for a close up use a tripod

------

you can also build a big rack instead of falling off the ladder - set the camera up & use a remote to trigger it - or use Nikon's app for your phone, which will let you see like you are looking thru the viewfinder

or move the LCD around to a convenient spot
