Works well enough
It would definitely get 5 stars if it went up to multiple stops instead of just 3/4. I lith print and sometimes I need to add up to 4-5 stops of exposure and it would be much simpler to use this instead of figuring it out in my head and calculator.
Works well for darkroom printing
Some suggestions for 5 stars would be to display a full stop to 2-3 stops higher as well in the same increments. It would be much more helpful then, rather than having to adjust the time manually to see higher stops. Otherwise though great app!
Must have for all darkroom fanatics!
What a genius app, at last a clever & effective tool that saves time & consistency with your prints. Def 5 stars!
