Perfect

Exactly what I was looking for. Ad free, Clean interface and accurate. Optimization for the iPad would be nice but still manages to look good when scaled up. It's hard to imagine what is improved in the developer's premium apps.

Life saver!

App does exactly what it says and is very accurate. It's been a tremendous tool for planning shots.

Fantastic Little App

I've never use this little app in the field. However, each time I go on a photo shoot I spend some time with this little toy, and the result has been that my hyperfocal points have generally been dead on. This app is an invaluable tool!

Great app

Wonderful little app. Perfect for helping me on my journey to zone focusing. I will be purchasing the paid app. The paid app lets one customize f-stops etc. thanks.

Wow!

Excellent little app. Intuitive, quick interface. No ads.

Needs a few tweaks

I like the visual indicators and I am okay with the idea of the shrinking DoF at smaller apertures. I want a readout of the slider settings (it could be in the slider legend area), "soft" stops on the sliders for common settings, and ability to tap and directly enter numeric values.

Does one thing and does it very well!

There are a lot of DoF apps out there but this one presents the settings and results in a very concise and logical way. After using it for a little while I “upgraded” to the full version (not the PRO version) to get the Hyperfocal distance function, although you can certainly get that from this app. Highly recommended for landscape photographers.

Nice GUI, BUT Diffraction does not decrease DOF at high f-stops!

A nice GUI design isn't everything. This app incorrectly shows depth of field decreasing above f/16 with 35mm format. That's not technically accurate: it's quite wrong. Diffraction, due to stopping down very far, does blur the image but does not affect depth of field. DOF continues to increase even as diffraction blur decreases resolution while stopping down. At some point the diffraction blur becomes bigger than the circle of confusion, which is chosen by the photographer for best results (or by textbook value or lens-maker value), but it affects all parts of the picture: at the plane of true focus, in the depth of field, and outside the DOF. At any rate, sometimes you need more depth of field than can be given by staying with your desired circle of confusion, so you may have to sacrifice some resolution to diffraction to get adequate (if less than optimum) resolution in front of and behind the main subject at the plane of focus. Also this app does not go down to macro distances like iDof Calc does.

Seems pretty accurate

I've shot controlled diffraction tests through all my cameras, and this seems quite accurate. The only thing I'd note is that it doesn't take pixel size into account. As the individual pixels on a certain size sensor decrease, the noticeable effects of diffraction increase. Technically it looks about right, but they should specify that the depth of field is still increasing at f16, f22, and so on, even though the image is becoming blurrier, which is an important difference in macro photography where diffraction limited images may be objectively better because wider apertures result in too shallow of a depth of field. 4 out of 5 only because they're treating DOF and diffraction as the same thing, otherwise this looks good and works really well.

This is perfect!

This has the best ui for such an app. Thank you for this! Though there might be a big with some settings are high than f11 where it goes to 0 and shouldn't be the case

Description

An elegant little app to give a wee taste of the TrueDoF range of depth of field calculators. TrueDoF-Intro shares with its sibling apps 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. The TrueDoF range is unique in that its calculations can take into account the effects of diffraction.

This gives the user a MUCH MORE ACCURATE indication of how sharp the image will be. Of course, if you're not comfortable with this diffraction business, you can simply disable that feature and instead use the app as a traditional depth of field calculator. You'll retain all the fabulous ease of use features! There's no need for long descriptions here — the app is free, so just play around with it. You'll find you'll never want to go back to the old ways of calculating depth of field. And if you like this version, wait till you try TrueDoF-Pro! Check it out, and its HUGE list of features, here on the App Store.
