    Cropping in post (or in camera, I often toggle apsc mode with a custom button) is a very important reason to want more mp.

      I use the APSC on a button all the time and it is the only reason I hope the next A7S or FX3 will get more MP Like 18-20 MP so I can use crop in 4k filming. apart from that I dont need more than that for any case

      For cropping we want higher pixel density. This can be achieved with the same or lower number of pixels by using an aps-c or mft camera instead of full frame.

  • @Comalv
    @Comalv Місяць тому +28

    like other have said:
    - Downsampling a high resolution image is a software process that yields very different results than shooting the same amount of MPX with a sensor that has that as native resolution. Remake this video using the best camera you can find that shoots at those MPX and then we can talk about it. Both of these scenarios are also different from cropping a high MPX image into a lower one. All these methods affect noise differently (Cropping also warrants its own section in such a video)
    - Cropping is a very valid use case for higher MPX count and it's an essential tool of a lot of genres (everytime you can't just "zoom with your feet", everytime you're photographing fast action and you want some leeway, etc.).
    The video premise is great, but you've barely scratched the surface with a methodology that is probably the least used one (downsampling a high MPX image) of the bunch.
    Also note that everything that is lower than 24MPX (without cropping) is probably a fairly old sensor, which also has to be taken into account if you want to say that it's good enough for a print.
    Surely in the days of old what was available at the time was good enough for prints that range from postcards to skyscrapers' billboards, but that doesn't mean the difference is not noticeable with what can be achieved today

    The nr one problem of your approach is, with scaling down you did processing first. And there you go, you have many pixels you can solve noise while maintaining details, then scale down and you have a nice quality low res picture. Now start with a low light, low res picture that you had to shoot on high ISO. The real question should be, how many effective pix do you need? Then there is the question, how much can you crop while maintaining sharpness with your lenses? A lot more with a 50MP compared to a 12MP.

A few seconds of thought on site can save a lot of time in editing later.

    A few years ago I took a photo of an elephant at the zoo with my 16mp micro-four-thirds GX85. I liked it enough that I decided to print it but I was worried about the quality because not only was it only 16mp, it was severely cropped into the elephant's face. But what the heck it's only for me personally so I sent out for a 36x36. It came out amazing. I can see all the detail of the eyes and wrinkles and I realized that maybe megapixels aren't everything camera companies sell us on.

    I got my hands on the 20 MP R6 and 45 MP R5 and upscaled the R6 files to match the R5 (you can pick MP output in Adobe Camera Raw). I then layered the files on top of each other without labelling them. My friend and I have about 35 years of photo/PS experience and even when zoomed in to 100% on 5K monitors, we often couldn't tell which was which. Our hit rate was about 50%.
    Then I used the Adobe built in Superscale feature to upscale the R6 files and then downsample them to match the 45 MP of the R5 and repeated the above. We picked the R6 files as sharper and more detailed 90% of the time. This was in portrait, studio and landscape photos using the best RF primes.
    Finally we did the same but used a free AI upscale on the R6 files, then downsampled to 45 MP and repeated the above. 100% of the time we picked the R6 files as sharper and more detailed.
    MP is truly overrated at this point. I think on full frame 35mm sensors that we have reached a near saturation point. I've also had billboards made from 8 MP 1D2N files that looked amazing!
    Because of this I got the R6 II (24 MP) instead of the R5 and got better AF, and other newer features and used the $2000 I saved on a 70-200 lens.
    The lens and AF accuracy makes a bigger difference than the MP ultimately. A 24 MP cam with a great lens and perfect AF will match or beat a 45 MP cam with a good lens and maybe slightly off AF. And even when all things are perfect for both the difference in real world (prints, etc) is not noticable anymore. And the same applies to cropping (as you can blow up the smaller files then crop though I never crop).

    I think you forgot about the Bayer. 24mp image out of a 24mp camera isn't the same as 24mp image scaled down from a 100mp camera. The difference in detail will be dramatic.
    So I agree that 8 mp is plenty when every one of those 8 million pixels contains all RGB information. And to get that - you need a higher MP camera.

    This experiment is just to find out how big a printed pixel people can see from a given distance, correct? That's definitely a valid investigation, but it's also a missed opportunity. Given your intro about how photographers always want more megapixels, shouldn't this be a test of the actual value of having a sensor with more pixels? (Spoiler - it's not just chasing numbers. It makes a difference.)
    I can take the same photo with my D750 (24 Mp) and my D850 (47 Mp), and see a clear difference at 100%. No surprise there. But even after reducing both images to, for instance, 2400 px on the long edge, the level of detail in the D850 image is still clearly superior. You should be testing the level of detail retained when images of different resolution are reduced to the same pixel dimensions. *That* would show the actual value of higher resolution sensors.

      I don't want to be mean but this test was clearly almost a ad for the printing company (and thats fine) so not really the use of the camera. The reason why many of us want/use high megapixel cameras is to be able to crop and/or zoom into a image. I think most if not all agree that a 10mp is fine in the end also we use images differently i can only talk for myself but i love to watch images on a 12.9" ipad and zoom in and out of part of the image at times there it also helps if i start with a 50MP or 61MP image.

    The billboard thing is how the Shot on iPhone campaign works so well. It's honestly genius marketing (per usual from Apple). Fun fact its also how their Retina Displays work. The pixel density is different on iPhones vs MacBooks because the average view distance is different for each product and therefore MacBooks needs fewer pixels per inch than iPhones because we hold iPhones closer to our faces.

    The real world situation of viewing and appreciating photos is even less strict. Instead of hanging 3 prints of the same scene side by side, you only have one print on the wall from whatever MP. The viewer’s attention is on the content instead of searching for detailed areas to compare because there isn’t another print to compare with.

      And often the viewer does not know how the objects on the photograph should look like or does not care about the details.

In wildlife, on the other hand, unsharp feathers or hair make substantial difference easily noticeable by other wildlife photographers.

I'll routinely crop my recent bird shots from 45 mp to 6 mp and they look great on the computer screen and would print great at 8x10, maybe even bigger. But If I'm going to print those, I'd probably export as TIFF to higher rez. Anyway, 21mp is amazing quality. So is 10 mp. What we have today as photographers is mind blowing.

    Unless your image's ppi at full size exceeds the ppi of the printer, you'll be hard pressed to tell the difference between a 20mp and a 45mp on an image printed at the industry standard of 300 dpi. Viewing didtance is the perceptual key. Even a 200 mp image at full size will show pixelation in a 5' print or a 2' print if get a foot away from it. That, and when you convert to a lossy format like jpeg for printing, you may as well be shooting 8 or 10 mp.

    Lots of additional technical comments here. A complex subject that I feel can be expanded on in future videos.
    Best use of higher MP in camera is the ability to heavy crop part of the image without loss of definition / sharpness.
    When you next open a large mp photo view it at 100% and scroll around the entire periphery of the image. You'll realise how insanely massive your photo is even if it is printed at 300dpi. Now of you were to half the dpi your print has the potential to be twice as big again and will look good at nose close. Now go twice as big again and it will look good at 8 feet away. All quite ridiculous for your average shooter who in reality had more than enough pixels with their 20 year old dslr 8mp.

    I print 45MP this big which comes ataround 220dpi final, and there is no way someone would see that, as ink by itself do merge between the dots, it's fluid, so no pixels will be visible unless you do something like very very low dpi stuff, and even then, if you upscale the image first with some AA to blend pixels, print will come out nice, without visible pixels/dots, only the details will be not there, but as long as sharp edges are not visible, nobody outside the pros would not see it.

    The one place more MP is handy is in action photography. I shoot sports and wildlife and being able to "shoot loose & crop tight" is a very handy thing. I used to shoot film and then small MP sensors when the industry converted to digital. Even back 3 years ago I was shooting a 20MP Nikon D5 and, although it worked, it wasn't ideal. Steve Fine, former image manager for Sports Illustrated use to say "there isn't a sports image that can't be made better by cropping closer" and it's true. Although there is another reason that this was true in print was because using up too much paper was expensive. We don't have that problem in digital. And although sometimes you want to show a sense of place in sports, mostly you want to more in very close to the action to pick up the expression on the athletes face and, if you're lucky, some dirt and grime. It's just more impactful. Same for wildlife. Sorry, didn't mean to be so verbose. Go video - very interesting!

      I would expect it would.

With a 16mp camera, I just had one of those pixels for input data - thus I would assume it not resolving as much color and detail.

    People should also consider lens' own resolving power. Even top end 24-70 f/2.8 lenses can't resolve more than around 26-32 MP according to DXOMark. While some primes can resolve better, many people out there will also be using lesser zoom lenses perhaps even kit lenses that won't be outresolving the 20MP sensor on their camera. TLDR is just don't worry about MP count.
    This is not the say video is done wrong, it uses a medium format camera to make these comparisons. I am just saying it doesn't really apply to most people out there. People with low MP cameras will also have low MP lenses on them. People who invested in Sigma ART prime collection or a 500mm f/4 will have a high end body which mostly comes with a high MP anyway.

    Maybe its because of the size, but when I go to a photo gallery or even a Peter Licht gallary or a museum, its quite often that I'm next to a 5' tall print and when I pixel peep, it looks quite bad.
    I think it comes down to the "texture" of the image. IE if I can see oversharpening artifacts, pixellation, jpeg artifacts, and occasionally chromatic aberration, it can look unacceptable and would stop me from considering purchasing the print. Other times, I've seen huge prints of a 35mm black and white film and it's super grainy but doesn't look bad up-close, because the grain is sharp even if there's no real detail.
    Maybe this test points to that the file you printed was well prepared. I'd love to see it done on larger prints and perhaps different subject material.

  • @waveland
    @waveland Місяць тому

    It’s all about the size of the finished piece, the freedom of movement available to the viewer and what you want to accomplish with the image. Basic boardroom art doesn’t require 250 megapixels. But for one project I printed a 16k x 8k pixel GFX panorama image at 10’ x 5’ and no matter how close you get to the image, more details emerge. It never breaks down and pixelates. The print is right at the edge of the lens’ resolving power and limited by temperature gradients in the air. That was my intention and I went to a specialty printer who could reproduce that much detail. But at 36” x 18”??? Beyond overkill. Always start with the deliverable and know how that does or doesn’t match up with the equipment on hand. If there’s a mismatch. Rent. Oh and let’s not forget that the GFX 100 and similar cameras take 16-bit images which provides more refined color gradients which improves effective resolution. Some typical sized 16-bit prints do look and feel different. It’s subtle and requires a high end photo printer like the Canon Pro-1000 but sometimes it’s worth the effort.

      Cropping should be minimal if one plans ahead. As I gained experience I find I have to crop less often, crop less from the image when I had to, and a little bit of planning to get things closer in camera saves time because one has to fiddle less in the editing software. Overreliance on cropping is a problem especially since eventually one gets beyond the resolution of the lens unless the sensor size grows.

    I love your test, but I do like the math. I get the (distance-in-inches x 0.000291) which assumes 1 arc second of human acuity (sin(1/60 degree)). I am not sure why you divided by 2. Are you accounting for the Nyquist frequency or are you assuming 1/2 arc second of acuity? One thing I would like to point out is that this formula is based on a worst case scenario of distinguishing very high contrast lines (black next to white, think of power lines against.a white sky or black characters on a white background) vs lower contrast (different shades of green leaves) subjects, so the resolution will differ based on subject matter. Also, a 4x6 inch photograph is likely to be examined much closer than a 24x36 image, and the different resolution images would much more likely be distinguishable if printed 4 ft x 6 ft using the same megapixel files. Finally, my guess is whether someone would hang something on their wall has much more to do with composition, color, and mood rather than resolution or Van Gogh and Monet would have been out of business. I use an A7RV because it’s the highest resolution I can afford, but I due process a fair number of panos.

    • @batuhancokmar7330
      @batuhancokmar7330 Місяць тому

      It could be better understood as ppi=2/(distance-in-inches x 0.000291). Its (probably) still 20/20 or 1 arc minute acuity as this is standard. 2 comes from the fact you need two pixels to differentiate a line. When you say resolving power of a lens is 60 lines/mm for example, you don't mean 60 pixels, you need 2x amount of pixels; 60 blacks representing lines and 60 whites representing spaces between lines.

The picture moves me. I want to see more detail. The brush strokes. The color differentials. The 3 dimensional view of the painting.
    Now, what resolution was a 6x7 print on slides when printed from a master printer wet. Take the negative and what MP can you get from a high end drum scan? Why was that so valued back in the day. The 6x7 and up to a 8x10 negative or slide? Because the picture printed allowed you to be immersed in it.
    If you want non art. Non detail. Non 3 dimensional. Cheap prints. I agree. Billboards were never about quality. If you want the best of the best print. Yes, you use high MP cameras. And never put it up against a pro printed wet print from a 6x7. Because it now will never match that quality still.
