Charged 3 times

Hello, I think I was accidentally charged 3 times.. once for 2.99 that went through immediately- once for 3.27 that is pending and once for 7.65 which is also pending. It doesn’t specify where form it just says Apple but they all came through at the same time 12:55-12:57 a.m.
I’m not sure how to reach the merchant about this issue, but other than that, helpful app so far!

Great app for learning

Love the app, it’s been very instructional. Any hope for medium format sensor support in a future update?

Great app for teaching

Love this app for the visuals. Makes teaching dof much easier. Any chance you could extend field size above 35mm to 120, 4x5, 8x10, etc?

No More Guessing on Depth of Field!

Wonderful app. I’ve used it now for several years and I love it. If you want to know FOR SURE what portion of your photo is going to be in focus, this is the best app to see how changes will affect your depth of field.

One great discovery was that by going wider, you get more depth of field. Since many current cameras have high megapixel counts, cropping some of an image off of “the sides” is not an issue.

Awesome!

New improvements = a great app

The new functionality that changes the granularity of your slider movement as you move vertically is very helpful, and mitigates a long-standing issue I had with this app. I just hope that this enhancement is easily discoverable for new users!

Response from developer

I've added accuracy to the sliders. If you move your finger vertically while sliding, you can be much more precise in your values.
