相信我！你根本不需要高像素的相機

OK, I need to see closer, here Enhance What? That's awful I have wasted so much time studying spec sheets, comparing cameras based on their resolutions It was only when I started experimenting with lower resolution, older cameras that I found the threshold for resolution was significantly lower than what I'd expected Many years ago, I owned a 30MP camera At the time, I never even thought about it Because I was using this Canon EOS R primarily for video Since then, I've actually been using cameras with lower and lower resolutions But at the same time, I'm finding the quality of my photography to be improving Whether it's many Micro Four Thirds cameras I've tested Or old CCD Canons with only 12MP of resolution I often had fun knowing that I was using kind of like an inferior out-of-date format Sorry Four Thirds sensors But getting to use older tech actually made me sort of let go of the stress of getting the perfect images sometimes It was always this endearing factor of thinking Oh, what can I make with such a low quality sensor? What if I actually made an OK photo? But honestly, from doing this and then using higher resolution cameras as well What I've found has been surprising and actually quite reassuring You might think that 12MP or 16MP is nowhere near what you need for street photography But after what I'm going to show you in this video I think you'll change your mind I want to show you some examples of where you're likely to view images today Say from a smartphone or from a desktop monitor Or a laptop or a standard 1080p or 1440p monitor Your smartphone For an example here, we're going to use the iPhone 15 as the benchmark I know Android have better resolution screens But hear me out The iPhone 15 has a screen resolution of 2556x1179 That comes through as a 3MP display Bit of a shocker And then think how small an Instagram image is on that screen I thought, OK, OK, like smartphone resolutions are going to be lower It's a smartphone Some Androids are going to have higher resolution screens iPhones typically pretty lackluster But phones out of the way It's going to be my large 4K monitor where the difference is made This monitor is from LG It's 4K IPS And really, really good in my opinion And it's where I edit all my photos and all my videos While I'm not using just my laptop But quickly talking about my 13-inch MacBook first Which has a screen resolution of 2560x1600 Which when we convert that to megapixels Is 4.1 megapixels That number is almost laughable My 4K monitor on the other hand is 4K So it's 3840x2160 Have you ever converted 4K to megapixels before? That is only an 8.29 megapixel display Like, what? So, OK, resolutions are low on screens Why should you care? Well, let's say you bought a 16-megapixel Micro Four Thirds mount camera Of which there are many and they're all really fun to shoot with They're super affordable and have great lenses When you take a photo on one of these cameras You can crop that image up to two times Before you notice any discernible loss in image quality When looking at it on a large 4K display Likewise, a 12-megapixel image from a camera like this Canon G9 From my a7S III From an original Canon 5D You can crop these up to 1.5 times Before you notice that same loss in quality I ask you this Do you still want to buy a Sony a7R? If you do, continue watching So if you're currently eyeing up a 33-megapixel flagship camera Or even a resolution beast like a Sony a7R With like 40 plus megapixels Hold on to your hats, people Because I want to show you what you can get out of a 12-megapixel sensor While saving you a ton of money and actually improving your photography What am I going to do with all of my photos? They look terrible But this guy actually makes quite good videos Can I just click subscribe? Hmm, nice, I feel good about that In the past, even when shooting on something With quite an average level of resolution On my a6700 I've shot at 26 megapixels Kind of like a wide shot And if I didn't like it I would just crop in to get like an Instagram crop Of the center of the frame And that was totally good enough This is an example of the bad habits That can form from Not lazy, it's not lazy sometimes There are some amazing photos that came from crops But came from like Just a, you know Pretty unintentional photo attempt I want to show you an image that I shot recently I was too busy looking at the subject And the details I was trying to line up To remember You're on a 12-megapixel sensor And we're currently probably A few meters too far back to make this work So because I didn't get that closer composition I then decided to crop in post And doing this has taught me two Very important but very different things The first is that I should always take the time To move closer for the better photo Take that safety shot a bit further out While you've got time But then take the time to actually move in And taking a few more photos as you get closer Until the scene changes And the second is Even with the crop I did On this 12-megapixel image Which is quite a big crop by my standards I still got a resolution of 2835 by 1894 Which gives me a 5.37-megapixel image Which is good enough for my MacBook Good enough for any 1080p monitor Good enough for my iPhone It's only when I put this up to full scale On my 4K monitor That I notice an issue But even then you have to look for it You might have come across An assumption kind of like a school of thought That lower resolution sensors Typically perform better in low light And with lower levels of ISO noise This is part of the reason That the Sony A7S line of cameras This is the Mark III Had the reputation of being the low light king of cameras This is because the size of each individual photo site On that 12-megapixel sensor Is larger compared to each individual photo site On a 48-megapixel sensor In fact they should be 4 times bigger Than those same photo sites on a 48-megapixel sensor And therefore they have 4 times the surface area To capture more light So it's the size of the photo site on the sensor Being larger allows them to perform better in lower light It's not about the size of the sensor in general 12-megapixels on full frame however Is not equal to 12-megapixels On a compact CCD sensor camera like this Due to the size of the sensors on these cameras And the size of the photo sites On each of these 12-megapixel sensors They're not both going to collect light in the same way So it becomes a balancing act of total number of megapixels Versus the size of the sensor And then what do you do with each of these But that's a whole other video Oh wow And so I can use those settings to make The photos on this camera look like Fujifilm photos Wow This specific video I'm talking about is actually amazing And you should watch it
