How many pixels do you need for good-quality photos? Solved/Closed

Question

Hello,   I would like to buy a digital camera, but I would like to know from how many pixels we can get beautiful, high-quality photos, as I already have one with 5 megapixels and the pictures are really not great. So, from how many megapixels do the photos really become beautiful and sharp? Thank you in advance.  When there’s a will, there’s a way! Configuration: Windows Vista Internet Explorer 7.0

Hello  The quality of a photo depends not only on the number of pixels but also, equally, on the quality of the lens and the color management of the software that drives the camera.  We talk about "photo quality" for a print of 10 x 13 cm from 2 million pixels.  I can’t emphasize enough: prefer a brand that has a long-standing reputation in photography, like Canon, Nikon, Kodak, Olympus, or Pentax. These digital cameras will have a good lens, good ergonomics, well-designed menus, etc. HP or Acer make very good computers but lack experience in photography, just as Panasonic makes good TV and video equipment and Sony excels in Hi-Fi (despite having bought Minolta)! BUT NOT IN PHOTOGRAPHY!  I develop 2000 digital photos a day... I’m well-positioned to see the differences.  There's also one point that should not be forgotten... unfortunately, digital shooting does not tolerate any setting errors at all... much like when we used to shoot slides. The light measurement must be precisely adapted to the subject. A little underexposed and noise appears, a little overexposed and everything looks washed out! (even with a high-end DSLR... yes, really) A problem that film no longer faces (this is called "exposure latitude"), as it can handle an error of + or - 3 stops. (In a disposable camera, there's only one setting... and it works, almost, in all weather!)  _________________ It's better to expect the predictable than to be surprised by the unexpected.

Good evening The fact that the photos are sharp doesn't depend so much on the number of pixels, but on how you take them. With 5 Megapixels you can have very sharp photos in 10x15. With a 3Mpx camera, I managed to take photos that I was able to enlarge to 20x30. A good camera among many others: the Nikon P80 for €380.  Claude

Hello there If you hope to print in large formats (80x100) or more, for example, you should count around 10 million pixels to have something well-defined on your paper... Of course, the higher your pixel count, the better chance you have of achieving remarkable image sharpness... (Also to be considered with the compression you use on your device and what you want to do.) See you soon and good luck with your purchase.

Critic friend Hello  Why so much hate?  I never claimed to be an expert or a "great photographer"... just that, having been in photography for 25 years (that's my job), I know what I'm talking about. The shooting data is easily imaginable when 80% of public photos look alike, showing the same subject in the same conditions!  The subject raised by pinkanenette talks about quality depending on the equipment and not on the photographer. We're not discussing "emotion" but image rendering. Even if you're right, you're missing the point; that's not the subject.  I could say that for someone who wants to discuss (on your site) the techniques of digital photography for everyone, aimed at providing the most complete information possible on digital photography while showcasing a gallery of film images ("The photos presented here are film") (which are indeed very beautiful), you're not setting a good example! That's strong! And who adds: "Today, digital quality is equal to film quality"... you forget to mention after how many hours of retouching in Photoshop and with what equipment. (I'm still talking about the general public... I haven't forgotten my goal... even my "knowledgeable amateur" clients find their photos to be of lesser quality since switching to digital and are going back to film)  As for "Can good photos be taken with a mobile phone? Yes." ... no comment   --  It's better to expect the predictable than to be surprised by the unexpected.

Hello Ami emcdeux,  I agree with you when you declare that "80% of public photographs look alike by showing the same subject, in the same conditions!" There is a simple reason for this: most amateur photographers do not master photography techniques. The website: http://www.gypsevideo.fr is specifically designed to help them.  Most great photographers today work with digital. A Canon EOS 1D (even an EOS 30), a Sigma, and others have largely replaced film. I have never said that a €100 digital camera is equivalent to a film camera.  Regarding pinkakenette's question, I responded exactly "To return to pinkakenette's question, the number of pixels is not a priority if he does not plan on making enlargements." Therefore, there is no interpretation to be made about emotion, about the photographer, what do I know?  To definitively conclude this discussion, showing differences in perspective (if I may say, viewpoint) does not imply, in my case, any feeling of hatred.  Best regards

Hello, I have been a graphic designer for quite some time, so I don't quite agree with the statement that the number of pixels doesn't matter for the quality of a photo. Pixel is short for picture cell, which characterizes the good resolution or definition of the image, since resolution is the number of pixels displayed in width and height.  P.S.: When the resolution is high, the image has better quality, but its size increases.  Please don't be mistaken!

mimossa · Answer

The number of megapixels doesn't affect the quality of the photo; the advantage of having a high number of megapixels is only during large format printing and allows for better cropping of the photo if necessary.  What’s important is the size of the sensor; on a compact model, the sensor is about 15 times smaller than on a DSLR, which results in a significant loss of quality.  There are three things that are important for taking great photos... A good camera, a good lens or lenses, and having photography knowledge. Having a $5000 camera won't help you take better photos if you don't know how to use those skills, especially how to work with light.  Stick to your budget; that’s the only advice I can give you...  If you're starting out in photography and want a good quality camera for an amateur who wishes to begin with decent quality, the Canon Rebel T2i is a good choice; it's not a professional model, but for an amateur, it’s very good, and they offer kits with the camera and a 55mm lens for about $800.

I read above that film cameras produced 16 megapixels for a good photo; I am astounded to read that because film doesn't have pixels, it is a continuous image on negative film, and therefore has nothing to do with digital cameras.   One could say that film is comparable to an image of resolution greater than what the best digital cameras can deliver, and thus the 16 MP are very far from it.

About pixels: I tried a Nikon D7100 with 24 MP. I was surprised by the image quality and especially by the usefulness of the pixels. I took a group photo of about ten people from quite a distance. I extracted each head with Photoshop and I was blown away by the quality of the images. I don’t think I would have achieved the same result with my D80 with 10 MP. I took a photo of some distant birds at sea. The 18-105 lens is not sufficient for this use. But with Photoshop, I was able to zoom in enough to identify some northern pintails... When will we have cameras with 1000 MP that will eliminate the need for telephoto lenses? One can dream!
