Hi @mjellings, fantastic to have you here :) Yes I can highly recommend to check your lenses for their capabilities. Don't look only for the sweet spot, but also for the area of acceptable sharpness. Not every lens allows us to be used on each aperture. Nice greetings, Christian

1:40 You can get that sharp with f/1.4. Learn the hyperfocal distance. I see that as beyond which focus does not really matter. At 50 mm and f/1.4 it is about 60 m. For each two f-stops it is cut by half. However , always focus on the main subject. Many beginners think that if there are great distances in the photo one needs much depth of field even though nothing is really close. However, it is not pin sharp. Depth of field is calculated using circle of confusion 0.03 mm on full frame. That is about one megapixel resolution.If you print it 60 cm wide the circle of confusion is 0.5 mm. As Tony Northrup said the biggest misconception of the depth of field is that it exists. The unsharpness increases linearly from the focal plane and at some point someone in the film era decided that it is sharp enough.

Hi @okaro6595, thank you for your thoughts! Hyper focal distance is usually not my first choice, to be honest, as it doesn't lead to the best possible sharpness. It just leads to the best spread of acceptable sharpness over an image. But that's not enough for me. Especially with higher resolutions of modern cameras the difference is huge and clear to see.

I get a lot of comments that people find it strange that I use Hugh apertures often because according to them it is not the sharpest for my set. But In my opinion its not all about that sharpnes. Sometimes I deliberately use the higher apertures to create a mysterious painty look to an image. Especialy when there is a bit of fog that works very well is my experience. I think it all depends on what you like best yourself. I often shoot multiple different apertures and look on the computer witch is the best.

Many lenses start suffering from diffraction at smaller apertures. This is why you lose sharpness at f/16 or f/22. Diffraction is light bouncing off of the aperture blades which softens the image. It’s also how we get sunstars. Most lenses are there sharpest at f/8-f/11. If you need more DOF than f/11 you should focus stack.

Hi Photo Dude, thanks a lot for adding your experience here, my friend :) It is all about the circle of confusion. Fullframe lenses are indeed sharpest around f8, but for aps-c for instance, it will be more something like f6.3. And it is also all about the material of the surface of all the elements inside the lens, such as aperture blades, for instance. Here is a huge difference between cheap lenses and quality lenses, for instance. Most of my Sony GM lenses have an acceptable sharpness between f2.8 and f18, whilst cheap lenses are indeed often just acceptable between f5.6 and f11. Just in case you are interested, I gave a lot more tips about sharpness in my sharpness video: Just in case you are interested: kzread.info/dash/bejne/hqaC0aeKo5bHhc4.html Thanks a lot for your comment, fantastic to have you here, my friend, Christian

I use an R5, and given the high MBs from the full frame sensor it behaves like an APS-C, so I try to not go above f8 as I really want , and have started doing focus stacking for really sharp prints at both near and far parts of the image ... I find the 'acceptable' sharpness that the standard depth of field calculations is way too soft (still based on out-dated 35mm values) so I don't trust them.

If you need front to back sharpness and you have a little time (like 30 seconds or more) I would personally focus stack (find out what the aperture your lenses are sharpest at and then do a stcak of images at that aperture for sharpest results, but you'll need a tripod for this). For moving subjects, it can't really be done, unless only part of the frame is moving (let's say the front is a bunch of flowers and the mid and background are mountains--then you can probably do this because in the other two or three shots (of the mountains) it doesn't matter if the flowers are moving because they will be masked out when the images are combined). I found this to be the best approach and honestly, faster than trying to find the hyper focal distance (which leaves less room for error). If I'm shooting at a smaller aperture, like f/8, it's a bit more forgiving and doesn't have to be exactly precise in many cases, except for maybe thing that are very close to the camera, like 10 ft away).

Hi @HR-wd6cw, thanks a lot for your insights, my friend. Fortunately, in most of the cases we have enough time, which allows us to decide on the best possible option after we have built up our composition. Of course, from time to time there are time critical situations as well where we have to react as fast as possible to get the shot. But in my experience, in situations like that when I have just 30 seconds or so, it is very unlikely to have enough time to use my tripod. It is more then that I throw down my backpack, grab my camera, and use an aperture where I'm sure that it will be enough to cover my entire frame with sharpness. Also if I would have my camera already on my tripod, there is a reason why the situation is time critical: maybe there is any special weather phenomenon or any special light situation. Focus stacking is a good technique, I often use that. But especially in time critical situations I usually try to get the shot in one exposure, as it is very likely that the "special light" will effect my distance layer, midground, and foreground. Focus stacking could lead to different light situations inside my frame. But when I have time instead, how it is in most of the cases, I choose the best possible technique for the particular composition. And when focus stacking is an advantage or even necessary, I use it of course :) By the way, hyper focal distance focussing is a fantastic focussing technique, but since I switched over to digital photography I use it just in very special exceptions. It simply doesn't lead to the best possible sharpness (just the best possible spread of sharpness over the frame), which is especially to recognize with modern cameras with lots of megapixels. I talk in my focus video a bit more about focussing techniques. How and where I focus. Just if you are interested: kzread.info/dash/bejne/mmtkpJubdcXPYco.html Thanks a lot for watching.

Focus on the main subject, not on some hyperfocal distance. I find stage how people talk at which aperture the lens is sharpest and the depth of field in the same context. Any lens at any aperture is way sharper than the requirement for the depth of field calculations.

Thank you for a great video Christian! Wow, there is really a lot to consider when choosing the right aperture for each individual composition which means there is no hard rule when it comes to landscape photography. In terms of determining the 'sweet spot' for each lens, how did you do that? Also, if the sweet spot for your GM 16-35mm lens is f9 and I have the exact same lens, does that mean that f9 is the sweet spot for all GM 16-35mm lenses, or does each GM 16-35 lens differ? Also, what impact, if any, does the body of the camera play on which the lens is attached? If you use your GM 16-35mm on a different body, will the sweet spot still remain at f9?

Hi Mark, I would recommend to start with finding out the sweet spot of your lenses and considering the depth of field, using Photopills, for instance. As soon as that works like binding your shoes, consider the additional tips I gave in this video. In the end, I promise you: all together will not be more complicated than binding your shoes. We have just to get used to it :) And to your question according to testing out lenes: I made a video where you see exactly how I tested my G-master lenses: kzread.info/dash/bejne/a5Wqk9x6esLdm7Q.html In production in general, there are always differences between the different loads and also inside a load could be differences between products. But as lenses need to be designed and produced quite accurate, I think there are not all too many differences between the products (of one and the same lens). Could be that there is a marginality between f9 and f10, for instance. But I can't imagine that there comes out a GM24-70 that has its sweet spot at f9 and another one at f13, for instance :) The only thing that should be considered are different releases. When there comes a new release of a particular lens, it could be that the sweet spot gets shifted, due to a change in the architecture. I generally test all my lenses, just to be 100 percent sure. But I test not only my lenses, also my other gear - also when the sweet spot depends on the lens, only. There are other things that can help you to get more out of your gear. I mention that all in the mentioned video. I hope this helps :) Have a great Sunday, Christian

I am not expert in optics and diffraction, and I have forgotten some of what I learned in school sixty years ago, but Dustin Abbot describes himself as a professional lens tester, so I expect he does understand it. I used to own a 5Ds, and according to Dustin diffraction becomes apparent at F5.6. Of course, it's worse with your 61 megapixels Sony, and any imperfections in your lenses your sensor can record more accurately. Now, I use a Lumix S1R for some of my landscape photography. At 47.3 megapixels it's close enough to the same as the 5Ds regarding diffraction. In its 187 megapixels mode, diffraction is not worsened. Usually, I focus where I want you to look and shoot at or near F5.6. I don't think there is any circumstance I would shoot at F16. Usually, close enough is close enough. Only a photographer would stand close enough to a big print to touch it with his nose, sensible viewers stand back to take it all in. If you can se what I want you to see, does the rest matter that much?

Hi John, thank you for your insights, my friend. The way you focus is how I tend to focus for clear figure/ground based compositions, such as portrait shots of a subject, for instance, whenever there is one clear area I want you to look to. Woodland scenes or tighter vistas is also a good example. For a wider vista scene instead with a more seamless figure/ground architecture, I usually want you to look to multiple areas in my composition :) We want to scan wider vista views. This has prehistoric reasons, such as making sure if the landscape has potential to survive. In such kinds of compositions we usually want to get our photographs sharp from front to back. This is why many landscape photographers tend to use something like f16 all the time for wider vistas. This works though, but this doesn't lead to the best possible image quality. I hope this video encourages landscape photographers who always tend to photograph with "the maximum closed aperture" to open it as far as possible to the sweet spot of their lenses. And yes, definitely - just a photographer tends to do pixel beeping. Viewers would not care that much :) Thank you for watching and nice greetings, Christian

Hi Omran, videography is not different to photography, here. The only difference is that your camera shoots e.g. 25 every second :) If you want to have a bokeh (blurry background) when filming people for instance in landscape, it is likely that you will need to use a neutral density filter when you want to open the aperture. But again, it is totally the same as for photography. Use photo pills to find out which aperture you need to get everything sharp you want. I hope this helps. Nice greetings, Christian

bokeh also changes with aperture, more important with closer subjects, where the background is soft...your DOF calculation shows quite clearly, that for a 'vista', where there is really nothing close to the camera, using that optimum 'sweet spot' is an obvious...well, not *so* obvious, selection. for many of the best lenses, one reaches opptimum sharpness only 1-2 stops from wide open, but, as per your testing, it's more complex for zoom optics, and undoubtedly changes a bit with selected focal length...

Hi Karhu, yes the testing process of lenses has definitely to consider the different focal ranges of a lens, as I did it in the mentioned video. I make a difference here between sweet spot and acceptable sharpness. Cheap lenses tend not to allow a high range here than quality lenses, on my experience. Thank you for mentioning bokeh. Yes, definitely :) Nice greetings, Christian

I watched a video a while ago where an accomplished professional landscape shooter did a focus stack using f16 on a static scene, nothing moving. I posted a question in the comments - politely - asking him why he chose f16 rather than opening up to, say, f8 to get the sweet spot on his lens. Unfortunately, he didn’t respond. I think I may have put him on the spot. It’s certainly a mistake I’ve made. I have a scene with a very close foreground and a very distant background so I automatically start at f16 to get as much depth as possible. Then I review my image in camera and see the foreground is soft; so I do a small stack of 2-3 shots to blend later. But I forget to open up my aperture to the sweet spot. Once we decide we need to focus stack, it doesn’t much matter if we take 2 shots or 5 for the stack, so we might as well get the sharpest aperture, right? Your video is a great reminder for me and also to use my PhotoPills app more often.

Hi Brian, thank you for your comment, my friend :) Focus stacking doesn't necessarily mean always to use the sharpest aperture on your lens. There are some situations when it gets better to use a more closed aperture, especially as the exposures have to be stitched together afterwards, seamlessly. Just think about a very close foreground for instance, which decreases your depth of field by focussing at it. I will make a video about how to master focus stacking, as there are a couple of things to be considered to really master it. But give me some time therefore, please. There are a lot of other topics in my topics&ideas pipeline, already :) Thanks a lot for watching and nice greetings, Christian

Hi @rellaxum, thank you for sharing your thoughts, which are quite interesting, I have to say! But I don't see any disadvantages for colours and contrasts in digital over film photography. In film photography we were able to manipulate contrasts and colours through various development techniques, such as different development times, different developers, and different development methods. In digital photography we can do even more: we can change colours in their tones, luminance, and saturation, and we can change also contrasts in post processing. For contrasts we can do even local adjustments, which gives us much more control over how the final image will get. Some years ago, I had maybe said, when using a good film, there could be some advantages in dynamic range over digital photography. But the dynamic range of modern cameras has got compareable, meanwhile. But anyway, interesting thoughts. Thank you and nice greetings, Christian

Your definition of Depth of Field is wrong. There is only ever one plane in a photograph that is actually in focus. DofF describes what is acceptably sharp behind and in front of the plane of focus. This is basic when using large format cameras where we often use f32, f64.

@christian.irmler

Жыл бұрын

Hi Robin, yes, that's definitely true. But with the way I focus on vista images, for instance, I have to say that I can't tell a difference when I compare a point in an image with that same point in a version of the image where I would focus exactly to that point, unless I would do extreme pixel peeping, zoomed in 200% or so. But it definitely depends on where you focus, of course. So, the "acceptable sharpness" in my images is indeed definitely always "pin sharp" :) Thanks a lot for watching and have a great Sunday, Christian

Hi @metaversebyloff, yes definitely, every aperture makes sense for a specific use case. But in my experience, in most of the cases there comes anyway the point where focus stacking starts to make more sense than accepting high diffraction. But also f22 has a right to exist, of course.

Good information but I feel the video is about 17 minutes too long considering the info given. In summary "every lens has a sharpness sweet spot, test your lens for that sweetspot. The more you want in focus in your focus plane/point of interest, increase the fstop but try not to exceed the lens sharpness sweet spot (usually around f8-11) The less you want in focus around your focus plane/point of interest, lower you fstop."

We need that and a lot of fun and duration when there are moving elements in our scene 😉 I'm just kidding, thank you for your thoughts, @demingdsw 🙂 It always depends. If possible I want to get my image with just one single exposure. Sometimes that is f/9, sometimes it is f/16. Important is, of course, to consider how good the used lens is at the chosen aperture. Some lenses show already a high diffraction at f/16, which makes it unusable. I even use f/18 sometimes on some of my lenses, when I know the particular lens still leads to reasonable quality and I need a high DoF. If necessary, I do focus stacking, of course. But that's not always possible in landscape photography. Especially when we are out in moody conditions, when the weather is rough 🙂 Thanks a lot for watching, my friend! Nice greetings, Christian

Not necessarily. If you want to photograph in the dark in woodland, for instance, you can go down lower with the ISO if you can open the aperture more. And that can be a quite big difference in image quality. It's really a big advantage to use the "right" aperature over always something like f/16. Enjoy your Sunday evening, Christian

If you really want to use the f-stop that gives you the sharpest image, find out what the hyperfocal distance is for the lens you are using, as a start-of point. if you don't know the meaning of the term, go back to school and find out why you weren't informed about it.

@christian.irmler

Жыл бұрын

Hi @freckitt2305, thank you for your thoughts! But to be honest, hyper focal distance is usually not my first choice, as it doesn't lead to the best possible sharpness, it only leads to the best possible spread of acceptable sharpness. Especially with high resolution cameras of today the difference is huge and clear to see. But of course, there are situations where hyper focal distance is necessary, especially when shooting freehand or shooting analogue. I mentioned more about the different focus methods, which I prefer, which not and why and even which focussing method leads to the best possible sharpness, in my focus video: kzread.info/dash/bejne/mmtkpJubdcXPYco.html Thanks a lot for watching and nice greetings, Christian

"What is the best possible aperture for landscape photography, is revealed in this video." So misleading. The best aperture is the one that conveys your vision. If you stop using what works for you in your creative process only because you are told to, your vision becomes somebody else's vision. I do agree that to maximize image quality is best to stay within the "sweet spot," of the lens aperture, but creativity is a different story.

Hi mund2, absolutely - the creative process is that what really counts. But when we are happy with our composition, when we want to get everything sharp in our images, which is for most cases in landscape photography, it is all about trying to get the image technical clean, as well. I saw photographers having the aperture closed too much and the iso increased at same time, because the exposure time was too long. It is good to know how far it is possible to go on the aperture :) Thanks a lot for your comment and nice greetings, Christian
