LensTutorial vs Photographer's companion

LensTutorial is about learning to use photographic lenses the easy way. The app wraps all lens calculations into one package and allows you to quickly see them in action. Learning photography can be easy and we encourage you to use our app to facilitate this process. LensTutorial allows to simulate photographic lens usage and display effects of lens controls manipulation. The app combines both visual and interactive way of representing information with classic DOF calculator functionality. It allows to quickly estimate and visualize the following parameters on one screen: Angle of view Total depth of field Near range of depth Far range of depth 35-mm equivalent of focal length Subject magnification All modern cameras of various makers supported.

/!\ THIS IS NOT AN APPLICATION TO TAKE PHOTOS, BUT TO HELP TO PERFORM SETTINGS IN MANUAL MODE ON A CAMERA OR A DEDICATED APPLICATION. This application will help you to abandon the automatic mode of your cameras that does not do everything and control everything. For more experienced photographers, it can simplify the settings by doing the calculations for you. In any case, it is not a magic application to make beautiful pictures every time, but it will allow you to find a basic setting to refine to get the best picture you think. It is aimed at professional or amateur photographers (basic knowledge is required) and offers the tools to: - Calculate the alternative/equivalent exposure (manages the ND filter and long exposures) - Calculate the depth of field, hyperfocal and simulation of Bokeh - Calculate the field of view - Calculate the shutter speed to freeze the motion of a subject - Capture/Photograph sunrise/sunset, the golden hours and the blue hours - Get the position of the sun, time of sunrise/sunset, golden hour, blue time and monthly calendar - Capture/Photograph the moon based on the phase of the day - Capture/Photograph moonlit landscapes - Get the position of the moon, the hour of moonrise/moonset and the monthly calendar - Capture/Photograph the stars, the milky way without or with star trails (Simulator) - Capture/Photograph the northern lights - Capture/Photograph the lightning and the fireworks - Calculate the best setting for an EV (exposure value) given - Calculate distance or aperture with a flash - Calculate the optimum settings according to the lighting of the place (Light Meter) - Calculate for the macro photo the possible magnification with a close-up lens or an extension tube - Calculate the print size - Time lapse - Get/Set the characteristics of a camera (sensor size, crop factor, sensor resolution, ISO range, shutter speed range, circle of confusion) A countdown is available for long exposures. If this app is right for you, you can switch to Photographer's Companion Pro (no ads with more features).
