TrueDoF Depth of Field Calc for Android

11 things about TrueDoF Depth of Field Calc

1. There are some types of photography, e.g, landscape photography, where it is preferable to work the other way around, i.e. first specifying the depth of field you want (by setting the distances to the nearest and furthest objects that you wish to appear sharp in your photograph) and, from that, determining the camera settings (focus distance and aperture) that will give you the sharpest possible image.

2. This elegant app shares with its siblings the same core features: A clean and clear interface, ease of use, real-time updating of output and, above all (but conveniently hidden under the hood, as it were), the most advanced depth of field algorithm you’ll find on the App Store.

3. TrueDoF is designed for photographers who want an accurate, versatile and easy way to calculate the depth of field produced by their chosen camera settings.

4. It is particularly important that the effects of diffraction be taken into account if you're using digital cameras with sensors smaller than 35 mm format, where diffraction seriously compromises image quality at the top end of the aperture scale.

5. And, if you would like to achieve insanely huge depth of field — with astonishing image sharpness — try the FocusStacker app.

6. Not comfortable with this diffraction business? No problem — simply deselect that feature and instead use the app as a traditional depth of field calculator.

7. In calculating depth of field, this app can take into account the effects of diffraction.

8. In using the app, you will notice that, as you increase the f-number, you reach a point where the depth of field actually begins to drop.

9. The TrueDoF range of apps represents a major step forward in working with depth of field.

10. You'll find you'll never want to go back to the old ways of calculating depth of field.

11. This is because, at such an f-number and above, diffraction produces so much blurring that you cannot achieve the sharpness standard (circle of confusion) that you have specified.
