Exposure calculator app problem
11 months ago

Is anyone familiar with this particular exposure calculator app?


I've been using it lately but all the images are underexposed.

Here's my procedure for a long exposure shot:

I'll compose my shot on the tripod.

Manual focus.

Put it in aperture priority mode (at f/16 for example) and see what the exposure time is (without ND filter).

Put on 10-stop ND, and viewfinder block.

Calculate using the app, setting the EV adjustment to +10 for the 10-stop filter.

Shoot in Bulb mode using a wired remote for the time calculated.

Another dark image!

I'm particularly confused by the two orange buttons at the bottom/left of the app screen. Are you supposed to adjust the bottom two values to match the top f-stop and ISO or what?
