Photo Calculators Professional

\$2.99

Rated 4.00/5 (2) —  Free Android application by Richard Nicely

Application Designed Specifically for Studio Photographers.

This tool based on user input will:

1.) Calculate the Field of View:
Gives actual dimensions Horizontally, Vertically and Diagonally, as well as the Angle of View in terms of Degrees and Minutes. As well as Equivalent Full Frame Focal length.

Example:
If you input a Nikon D7200 Camera and 50mm lens from 8 feet away the application will return the following values:
Horizontal Field of View: 3.68 feet (26 degrees 27 minutes)
Vertical Field of View: 2.44 feet (17 degrees 44 minutes)
Diagonal Field of View: 4.42 feet (31 degrees 30 minutes)
Approximate Full Frame Field of View: 76mm

2.) Calculate the Depth of Field:

Example:
With the above D7200 camera and 50mm lens from 8 feet away using an f/2.8 aperture the application will return the following values:
Depth of Field: 9.78 inches
Near Limit: 7.61 Feet (4.64 inches (47.46%) in front of subject)
Far Limit: 8.43 Feet (5.14 inches (52.54%) behind subject)
HyperFocal Distance: 154.34 Feet

3.) Give data about the Sensor and values used for Calculations:

Example:
With the above mentioned D7200 the application will return the following values:
Sensor Dimensions: 23.5 mm X 15.6 mm
Crop Factor: 1.53X
Circle of Confusion: .019

4.) Calculate Reverse Depth of Field
Will give you either the Focal Length (to nearest mm) or the Aperture (to nearest 1/3rd stop) needed to obtain your desired Depth of Field.

Example1 Aperture:
With the above mentioned D7200 and an 85mm lens from a Distance of 8 feet if I want a Depth of Field of ~4 inches, the application will return the following:

An Aperture of f/3.5 gives:

Depth of Field of 4.16 inches
Near Limit: 7.83 feet (2.04 inches (48.92%) in front of subject)
Far Limit: 8.18 feet (2.13 inches (51.08%) behind subject)
Hyperfocal Distance: 356.73 Feet.

Example2 Focal Length:
With the above mentioned D7200 from a Distance of 8 feet using an aperture of f/2.8 if I want a Depth of Field of ~ 4 inches, the application will return the following:

A Focal Length of 78mm gives:

Depth of Field of 3.96 inches
Near Limit: 7.84 feet (1.94 inches (48.97%) in front of subject)
Far Limit: 8.17 feet (2.02 inches (51.03%) behind subject)
Hyperfocal Distance: 375.46 feet.

5.) Calculate Lighting Ratios (using either of the two common methods)

Using either the pure "Power" ratio between the two lights (K:F) or the "Lighting" ratio between the two lights combined and the Fill light ((K+F):F) if you input the meter reading for 1 light and the your desired lighting ratio, it will tell you what the reading on the other light should be.

Example 1 (Power Method return Fill light value):
If you enter a meter reading of f/8,"Key" value, and "Power" method for a Ratio of 4:1 the application will return the following:

Fill Light Setting should be f/4

Example 2 (Power Method return Key light value):
If you enter a meter reading of f/2.8,"Fill" Value, and "Power" method for a Ratio of 7:1 the application will return the following:

Key Light Setting should be f/7.1

Example 3 (Lighting Method return Fill light value):
If you entered a meter reading of f/11, "Key" Value, and "Lighting" method for a Ratio of 5:1 the application will return the following:

Fill Light Setting should be f/5.6

Example 4 (Lighting Method return Key light value)
If you entered a meter reading of f/4.5, "Fill" Value, and "Lighting" method for a Ratio of 3:1 the application will return the following:

Key Light Setting should be f/6.3

The application settings also allow you to choose between various background colors.

What's Changed
1.) Added new "Reverse Field of View Module"
a.) This module will allow you to specify what Field of View you want in either the horizontal or vertical direction, and tell you what Focal Length to use to obtain it.
2.) Added "Miles", "Millimeters" and "Kilometers" to the options available on the distance unit spinners
3.) Put limits on number of characters that can be entered in the various edit text fields.
Price update  Price changed from \$3.32 to \$2.99.
