A: Calculate the parameters for both the minimum and maximum range of your lens - this way you will understand what happens to the different parameters (depth-of-field, for example), when you are zooming in and out of a subject.
A: Look at your camera's technical specification in the owner's manual or online for the sensor size/format of your camera. Use the "Other" category to see the generic sensor sizes and select the one that best matches yours. Also - please let us know, we're constantly updating and adding to our database and we would love to hear from you!
A: Tap the "Unlock" button to unlock the target exposure and set to a different number. If your picture was too dark, set it to "Overexpose"; if it was too light, set it to "Underexpose".
A: Photo Helper uses a wide range of both shutter speeds and apertures for its recommendations to accommodate a variety of users. Due to this, it is possible that the recommendations presented are outside the possible range for your camera/lens combination (for example, an aperture of f1.4 when your maximum aperture is f2.8). To correct this, simply adjust the appropriate slider in the "Fine Tune" area until you get to a parameter that is appropriate.
