Please reimburse me I will not use this up Thanks ### 1/5 — Nothing but a chart. *2021-08-30* This is just and interacive chart. It does NOTHING! I paid $9.99 for a chart. Save your money. ### 1/5 — I don't understand why the app doesn't let me choose my f-stop *2014-08-23* There's some weird blur diameter slider and the app chooses your f-stop for you. This is counter intuitive. I want to choose my f-stop and have the app tell me number of steps and distance between. ### 1/5 — It should be called Landscape stacker... *2014-05-21* Too bad I discovered only after paying that is useless for macro.... And even for landscape the fact that you can not select the f stop you want to use also is a big problem, what if you want to use a 10 stops ND and use a specific f-stop? Or if you know that the sweet spot of your lens is different than the one suggested by the software? Also it will only work up to 10 stacks... ### 1/5 — Macro photography enthusiast *2014-03-09* The instructions for this app tell you it's designed for landscape photography, and is "emphatically not" for macro photography. It stinks that you can only discover this *after* you've paid for it. It's definitely useless for macro photography - it doesn't attempt to convey useful distance information at close range. Developer should have included warning for macro enthusiasts in software overview. ### 2/5 — Be Careful: READ THE DETAIL *2020-06-23, version 4.1* Hidden in the deep text. This app is a visual spreadsheet, not a cool app that actually uses you mobile to create great pictures. Do some research, make your own spreadsheet and forget about this app. It will take you a week or more before you'll actually know if this app is any good. Select setting, make notes, setup camera manually, take shots, export data, buy stacking software, import data, fiddle about learning new software..... get a result... hmm was it worth it? ### 5/5 — Excellent, Smart Calculator *2025-01-22* This is an excellent interactive visual calculator for optimizing focus distances and aperture when focus stacking. It may be more optimized than necessary in many field situations, but if you need the best guidance and have the time to apply it, you will be pleased. ### 5/5 — A Must Have App for the Serious Photographer *2016-01-02* How sharp do you want your final focused-stacked image to be? Let this app know and it will tell you what to do. It delivers perfect results every time. Without this tool, you are merely guessing on the decisions you need to make. How many shots? Where are the shots focused? What f/stop? Yes, photography is an art, but this part of it is a science. So if you want to get the very best results from your camera and lens, do yourself a favor and get this app. ### 5/5 — snr *2014-12-04, version 2.0* Hi, found it to be a very useful app in landscape photography and for those who complain that it should state that it is for landscapes, it is in the description!. ### 5/5 — Amazing tool for depth of field *2013-06-27* From foreground macro to the distant horizon - crisp as! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
