Thank you so much comrade, after watching about 20 videos and reading even more articles I finally found your video and finally understood the hyperfocal distance and how it relates to depth of field.
Hi Rafael, excellent! I'm a new user /subscriber,. The video is a clear and concise description AND explanation of what depth of field is, how it is / can be used, and how the PhotoPills app can make it visible and more user-friendly. Love the AR function, too.Thank you!
Given the same image in the viewfinder, the DoF is the same with any lens. The compression or expansion of the distance along the lens axis, however, changes.
Thanks Rafael. Your videos are very helpful. You mentioned being careful not to close the exposure too much. How much is too much? How do I figure that out? Thanks
thanks for the informative video. I did not see any discussion of about COC nor what happens for different cameras/lens when the subject is the same size in the sensor. Perhaps this is an advanced course?
Thank you for the great app and great videos!! While you’re on the topic of DoF, I have a request. Wouldn’t I want to change the Focal length in your DoF calculator, when my iPhone is using an add-on lens, such as the Moment 58mm Telephoto lens or an Anamorpic lens? Maybe have a Default or Revert option to put it back to the iPhone’s Fixed focal length, assuming we’ll never remember that value. Thanks!
Hi Rafael, excellent content as usual; my main genre is macro-photography and it will be very useful if you could implement the possibility to change the metrics from mt to cm or better mm, in order to calculate the depth of field using RR up to 1:1 (or subject distance less than 1 mt if you want...) do you think it could be feaseble? thanks a lot in advance
Hi Giovanni, thanks for the suggestion. We should build a specific Dof macro calculator that works. Not easy to get something accurate. But it's in our to do list
@@PhotoPills Great!!! Looking forward to see the update!

hi! i have a question, but not about the video content it self, I would like to know to do you create the sections on the video with "introduction" "what is depth of field" and so on.. thanks!
Like always a very sympathetic video about this wonderful app! You also talk about diffraction, you say we have to take care. But how? There are also apps which calculate diffraction. Will photopills also consider in future diffraction in calculating the depth of field? That would be amazing! Thanks again for this genius app, and sorry for my bad english. Greetings from germany - mark
Yes, we will implement a diffraction calculator in PhotoPills in the future. In the meanwhile you can use our online version: www.photopills.com/calculators/diffraction
@@mark-gross Rafael answers every question asked of him. Really a remarkable app. First app that’s made me wish I had a DSLR camera, not just an iPhone.
Hi Rafa! Could you show how can we get a crisp focus of a large bright object like Sun or a huge lamp? When I try to capture, the edges are never crisp and there is always light bleeding into the whole photo. Please help. Thank a lot
hello Rafael thanks for all this very importante information. i plan to use your app but i have problem i use sony camera super 35 but all my lens are canon or olympus so i use speed booster metabone .are the calculation afected ?how to use it if there is a way thanks
Bought the app. Just not 100% clear on the wordings for the DOP calculator. If i enter the camera model, does entering the actual focal length of the lens means the calculator will automatically add the crop factor since it knows the camera is crop sensor. I am a little confused with the wordings of the actual and 35mm equivalent options.
Welcome to the tribe! And yes! When you select the camera model, PhotoPills takes into account the crop factor automatically. So you need to introduce the actual focal length your setting in your lens, not the 35mm equivalent.
i have a new problem, wich camera shoul i use for aumented reality ? i can choose betwen 11mm, 26mm, 3rd 26mm and a 56mm. dose it change something or its just the way i will see it ? Second problem: since the last update i can't see the moon movements in augmented reality in planning , just a line with time stamps you guys have this problem? i have a huawei p30
It changes the angle of view, as it uses different cameras of your phone. For example, you can use the Night AR at 11mm and you'll see it like using a wide angle. Or a 56mm and it's a medium lens. The info displayed is the same, but it's like changing the focal length in your camera. The second problem. You probably hide the moon info in the Planner. Tap the Map Settings button, the one at the right side of the + on the map, and then tap the "eye" icon of the Moon layer.
Hi Rafael, very useful video, thanks for it! I'm interested in implementing new algoritms in terms of the depth of field. Could you provide the equations where you obtain the different focus distances? I found this one: en.wikipedia.org/wiki/Hyperfocal_distance Another question that I don't understand. To my understanding, the depth of Field is the area of the image where the focus is acceptably sharp. The hyperfocal distance, the distance from where the rest of the image will be in focus. How is it possible that the DoF far limit is 7.52m (meaning, the end of the acceptable focus) and the Hyperfocal distance is 14.81m? Thanks!
Because the calculator always shows the hyperfocal distance and the DoF you get when focusing at a spedific distance. The 3rd button is the focusing distance, you can change that to see how DoF changes. But the hyperfocal distance doens't use this value. Regarding the algorithms, just check the wikipedia, they probably have the correct ones.
In the AR view should appear the selected focus distance in the calculator. In meters, each mark is drawn at 0.5 m. In feet, each mark is drawn every 1 feet.
@@PhotoPills Thankyou for replying. I understand what you are saying, but the 5 ft mark in the AR view appears at the 2 feet mark on my floor. 3 feet off. Otherwise it's a great app.
I have been a photographer for years and learned how to use hyperfocal distance a long time ago while still shooting 4x5. I am trying to leave some of my old time consuming ways of doing things behind and rely more on your app to speed things up and have more precision. Please explain the difference between Hyperfocal near limit and DoF near limit? Also why is it important to know the depth in front and the depth behind? I think these just add confusion to this part of the app. An example of why I should know this would be good. Finally can I assume IO means near focus distance and OI means far focus distance while viewing om AR? Sorry to have so many questions, but I can not find "clear" explanations in your help videos or text.
The "Hyperfocal near limit" is the "DoF near limit" when you focus at the hyperfocal distance. If you set the focusing distance as the "hyperfocal value" you'll see that both fields has the same value :) The near/far DoF is really useful to know the DoF distribution. Play with the calculator and you'll see it's not always 50% in front and 50% behind. So, it's important for example when shooting portrait to really know what will be in focus and what not. If we'd only say there's 2 meters of DoF when focusing at 5 meters, how would you know from where to where you'll have acceptable sharpness? :) The only way is by giving the DoF near and far limits too. Finally, the "|O" symbol is the "near dof limit" and "O|" is the "far dof limit"
@@PhotoPills Thanks you for your helpful response. I guess my confusion....not to be confused with circle of confusion....comes from the share volume of information your wonderful app provides. Thanks for clearing things up for me. Just as an aside, I still see no value in converting near and far values to percents. Just my opinion and no need for further response.
Just left a question on the hyperfocal distance video, now I have another. I have a full frame mirrorless Canon, but some of my lenses are not the F lenses that actually use the full frame, like the 17-40 is an ES lens, not EF. How do I accommodate for that? Buy new lenses😀?
@@tmhart43 In this case instead of selecting your full frame camera, just select a crop-factor Camera that has more or less the same megapixels as your camera in crop factor mode.
So does PhotoPills work globally? I am living in California but I travel the world. I've seen reviews; although they are a bit old; that said your app is only good in a certain area? (Europe if I'm not mistaken)
I LOVE PHOTOPILLS! In fact I promote your sites 3-5 times per year. My friends' typical response is "He speaks so fast and I don't know what to expect what's coming that I just get lost and give up". I realize that your universe is the entire photo world (and beyond) but your English, especially when spoken machine-gun quickly, is nearly impossible to understand, even when there's a reasonable expectation as to what's coming. I don't want to sound English-arrogant but suggest you ask someone who's fluent in accent-free English make your videos. I'm a fan but am exhausted beyond use after just three minutes this time..
Hi Calvin! Thanks for the feedback. As you know, we're a small team... and everything is home made. I hope in the future we can hire somebody fluent in English. In the Meanwhile, you can slow down the video via the youtube settings. That will probably help.
These calculators are wrong. If I take a 100mm lens at F4 and I am 5 m away from my subject, the DOF ought to be fixed. There is no “framing”. The smaller the sensor, the more you crop because your FOV changes. How can you reframe by changing the distance? You chose the distance already. If I take a photo and crop it in, nothing changes about what was in focus and what was not. Art students and maths dont mix.
A smaller sensor requires more magnification so there is less depth of field. I find your arrogance strange. A textbook example of Dunning-Kruger. If you crop and ENLARGE then the depth of field naturally decreases.

Great videos and app! Is there any way to plug in an infrared factor for converted cameras to account for the longer wavelength?
mmmm.... we need to study that...
