Quick and Easy: Use LensTutorial in the classroom and in the field
Now you don’t have to tap the numbers into the boxes. LensTutorial is quick and easy to operate in any photographic situation. Just slide Aperture, Zoom or Distance rings with one finger and get updated values of depth of field info, angle of view and subject size. We’ve tried many DOF calculator apps for various platforms including iPhone and iPad that could have become great products. However they often lacked the two features that we...
Visual and interactive: Rotate zoom, aperture and distance as in real lenses
LensTutorial visualizes all changes you apply to lens controls by displaying cone of view with focus point put on the eyes area of photographic subject. Exact values of calculated parameters are displayed as well. Slide the controls and see how simulated world responds. A very important property of LensTutorial is showing “it all” a once. There are apps that can show Angle of View, but for DOF you’ll have to download something...
Real: You can trust DOF, angle of view and other calculated values
LensTutorial tries to be as close to the real world as possible. We’ve taken real lens controls as prototypes and tried to use rotation metaphor as main gesture in the app. Visualization allows you to estimate what part of the scene in real world your model will occupy at given distance and focal length, how much Depth of Field you have at your disposal and what are the near and far ranges of DOF. You also get hard numbers measured in units of...
Focal length
Learn how focal length of a photo lens affects your view of the subject. You’ll be able to play with different focal lengths and see how they work. That helps to decide if you actually need to buy that expensive telephoto or an ultra wide zoom lens.

How angle of view is affected by a zoom lens that you have? Tweak the visual controls of Lens Tutorial application and see for yourself. Did we tell you that you’ll also get hard numbers if you want?
Read moreDepth of Field (dof)
Depth of field (abbreviated as DOF) is a very important concept that is best understood visually. Use Lens Tutorial to manipulate all your lens setting and see how DOF responds. Choose shallow depth of field to isolate your subject. Set large depth of field to add more detailed objects to the view.
Read moreSubject distance
Distance to subject is important in photography. See at what distances you can shoot given a choice of lens parameters. Or modify distances to see how other lens numbers accommodate to it.
