Great app for teaching

Knuckledragger999

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?

Does exactly what it says.

Nice little app. I'm just getting into photography that doesn't involve the AUTO setting. This will help visualize the effects of the different settings. Nice work.

First off, nice app by the author. It provides solid information regarding depth of field. However, while reading through the information page I found myself annoyed by the misinformation the author provides regarding quality of Dale cameras based on their sensor size. While sensor size does have certain impacts on a DSLR, it does not specifically define the grade or quality of a DSLR. This is just my pet peeve, and if you ignore the authors bias in the info page, this is a good app. I'm keeping it on my iPad.

Excellent!

Great for someone like me who is just starting out in the world of DSLRs.

Good app.

I like that it is easily manipulated via the touch interface. The ability to drag the background is a nice added touch.

Decent app

This is a very easy to use app, with a simple to use interface. If you are just looking to know the DOF for a particular setup, this is the app for you. I especially liked the slick visual representation of the lens view and the movable background. Objects are roughly to scale, so it gives a pretty good idea of what would be in focus. Unfortunately, this app is missing a measure of the viewable area. It does calculate the angle of view, but if I wanted to do the math, I wouldn't buy this app. Displaying the dimensions of the viewable area at the plane of focus (how tall and wide the plane is) would help in planning shots. It would answer the question, "How far from a person do I need to be to get a full length shot at 85mm on a 35mm sensor?" That isn't something the current app answers. For me, adding this additional calc would make this a 5 star app. If you don't need that, this is already a 5 star app IMHO.

Best tool yet for helping visualize a shot

Freaking love this app. In 30 seconds it taught me what two years shooting hadn't ... that shooting a long lens wide open means your depth of field is about 3 inches. Sliders and a visual index that gives you an idea of the relative size of things as they'll appear in frame make this the best lens tool I've run across yet. Great for anyone shooting rangefinders as well.

Really nice

This is a really well thought out app, nicely put together.

Pretty, but lacking

While the app does a nice job of a physical presentation for the DoF, I was rather put off by the lack of options for the sliders. For instance, the focal length only let's you go to a maximum of 200. The aperture settings had some strange numbers ( 5.7? ). It was also lacking some apertures - for instance, my Nikon D90 has f/10, but that's not available as an option. Finally, there is no place to put in the circle of confusion number, nor does it maintain a camera database. This means that if your camera has a different circle of confusion than the 3 the app lets you choose from, the calculations are skewed. It looks pretty, but other DoF Calcs have more flexibility and better customization.
