Absolutely the best app I have ever seen. I can now show a student in 2 seconds a scenario that most people never understand. Thank you for creating and sharing it with the rest of us.

This app is terrific if you want to determine the depth of field you'll get with different camera settings, such as lens focal length, focal distance, and aperture f-stop. This was recommended to me by a photography pro in a photography course I took. Very useful!! Easy to use also, a must have for photographers.

bonjour , je ne peux pas avoir accès aux paramètres de l'application, qui peut me tuyauter merci

A damn good app! Suggested that I get this from a buddy as he too loves it.

This app does an amazing job of quickly producing a visual representation of most shooting scenarios. However, the height of objects along the field of view isn't precisely known and as the lens length increases it gets harder to understand how high the focal area is. Shooting a portrait at a length of 135mm on the app shows an in focus working distance compared to a tree instead of a person. But if we knew the height of the focal plane we could compare to our subject better. That would help!

An excellent teaching tool,. Makes it easy to explain hyper focal focusing. Be nice to see a tool such as this for exposure.

Works good on moto g

Good app but I can't see the 3 dots to go to settings. . Please fix it.. (update) even after a year later from my 1st review you didn't fix the 3 dots menu

Great app, but its not what I thought it was. I can't use it. can I please get refund, thank you.

Easy to use and understand. I'm new to Android, and the dev quickly responded to my query on how to access the settings/help guide (try holding down Home on your phone if you're a recent iPhone user and get stuck looking for settings.)

Simulator works perfect but each time we exit the app it is resetting to default...

The DOF calculator can be found on any number of apps but the perspective simulation is very unique and it lets you estimate real life situations. Basically the app estimates the angle of view for the lens length you input, then puts lifesize objects on a distance scale to give you an idea of what youd be framing. At 11 feet, you see that a 45mm lens frames most of an adult body, and gives 1ft dof at f4 (or something like that). The problem is, at 6 feet I can only size up a bunch of cats and dogs, and at 30 feet I can only look at airplanes. I would LOVE it if there was a way to just look at that adult human at different distances. This way you could say "if i want to use a 50mm lens to frame a person's head and shoulders, I'd be about X ft away and need at least Y aperture."

I have been jealous of iPhone users for this app for a year, so I was so glad to see it available for my Droid that I downloaded it the first day it was available. I have never seen a clearer way to demonstrate depth of field, and certainly never had access to a dynamic demonstration that I could use to determine the best f.stop setting for my camera when I'm out and about and actually using it. The interface is really intuitive, and the images that the developer used to illustrate what would be in focus at what focal length + f.stop really work for me. It's easy to use and helps me take better pictures. This is a must-have if you have an SLR! P.S. I am using this on the Droid 3 running 2.4.3

I'm an amateur photographer with 3 years experience using a dslr camera/lenses. This app really helped me learn how focal length, distance and aperture affect the depth of field. The interface is fluid and easy to understand. I recommend bringing a device with this app along when you shoot to get a feel for how it can help you compose shots. Also, the help section is a must read. The designer does a terrific job explaining the terminology and how the interplay of these variables affects the outcome of your shots.

This is the best photography app I've ever purchased. I've learned more in the past 24 hours than I have in all of the reading that I've done on the subject of depth of field.
