Megapixels for Digital Photo Printing at 200 Pixels Per Inch (ppi) How many megapixels (MP) are necessary to produce a high quality digital photo print? Though several factors affect print quality, this page focuses on image resolution, providing answers for questions such as: How many megapixels do I need for a 4x6", 5x7", or 8x10" print? When buying a camera, how many megapixels should it have? What are the acceptable resolutions for various print sizes? What are the minimum megapixels required for posters?

Print sizes up to 8x10" Common photo print sizes like 4x6", 5x7", and 8x10" are generally viewed at an arms length, requiring a higher resolution image for satisfactory results.

Mirrorless Camera Lenses.
When it comes to mirrorless camera lenses, you've got options. The main reason that you've got options is that you actually CAN change the lens on a mirrorless camera if it suits your mood. From wide angle panoramic views to detailed close-ups, you can select a lens that goes along with your photography style, or to capture a specific type of subject. With the right lens adapter, you can also make your mirrorless camera work with a huge number of standard DSLR lenses. Since you do have so many options, it helps to have a basic understanding of lens jargon before you dive in.
Focal Length The first mirrorless camera lens feature to pay attention to is something called focal length. Here's what focal length is all about: It should be noted that telephoto lenses also ENLARGE distant subjects. Here are some examples of different lens focal lengths: Most mirrorless digital SLR cameras come with a "kit" lens. Maximum Aperture The wider a lens can open, the more light it lets in. Lens Choices. Depth of Field - Digital Photography Tutorial - Focal Length - Opinion.
The perspective-flattening of long lenses can also be used in other circumstances, because they also have the effect of reducing depth of field. You can use this to isolate a subject against its background by blurring it out, as in the shot below. Compare this with the same shot but taken with a wide angle lens from a much closer range. The relative size of the statue is the same in both shots, but due to the increased depth of field in the wide angle shot, the background, although apparently more distant, is much sharper. Because of this reduced depth of field, careful focusing with a long telephoto lens can pick out individual subjects amidst cluttered surroundings, such as a single person in a crowd.
Note also that the perspective-compression effect makes the street look a lot busier than it really is. The same scene shot from the same position using a wide angle lens shows the street (High Street in Exeter) in a very different way.

Digital Photography Magazine - Your #1 Guide for Better Digital Photography | DPmag.com. Digital Photography. En Photography has changed the way people record and remember images, events, and scientific information. Photography, which started in the mid 1800's, has continued to evolve over the last two centuries of scientific discovery.
The development of flexible film in the late 1800s, color photography in the mid 1900s, and automatic cameras in the late 1900's changed the way photographs are taken and presented. The most recent addition of digital photography has also changed the way people collect, store, modify, disseminate and display images. Digital photography started with the advent of the first commercial digital cameras for consumers and professionals in the early 1990's, along with the first systems for digitizing film images.
As the technology advanced, the cost of digital cameras and film digitization services has dropped, and the image quality has increased. As digital cameras evolve, the requirements for the file format used to store the image data continue to evolve also. CINEMATICS. Equivalence. Let's begin by considering a couple of experiments you can do at home. Take a photo of a scene at, say, 35mm f/5.6 1/200 ISO 3200 and 70mm f/5.6 1/200 ISO 3200. Crop the 35mm photo to the same framing as the 70mm photo, and display both photos at the same size. These photos have the same exposure, and are taken on a camera using the same sensor, thus the same efficiency and pixel size.
Which photo is more noisy and why? Here's another experiment. Take a photo of a scene using RAW that is "properly exposed" at f/5.6 1/200 ISO 3200. Answers are at the end of this section. Noise. When people refer to noise in an image, what they mean is the density of the noise in an image (NSR -- noise-to-signal ratio) and is often represented as a percent. There are two principle sources of noise in a photo: luminance noise and chroma (color) noise.
The more transmissive the color filters (weaker color filter), the greater the QE, and thus the lesser the luminance noise, but the greater the chroma noise. Learn Photography Concepts. Camera envy? Tips for using a point and shoot camera from Photo.net. Do you feel inadequate because you have a puny Canon SD900 or Fuji F30 in your pocket while your friend is lugging around a digital SLR?
Don't. You can get a better picture than he can, for the following reasons: Your camera is light and compact enough that you have it with you at all times. You have about as good a lens as he does; like most first-time SLR owners, he hasn't bothered to upgrade from the cheap low-contrast zoom lens that was included in a kit with his camera body. He is using the pop-up flash on his camera as his primary light. You would never be that uncreative (at least not after reading the rest of this article). Your camera has a better system for combining light from the flash with ambient light ("fill-flash"). A professional photographer with a pile of $1500 lenses and a tripod is going to be able to do many things that you aren't.

This review is intended to help you choose the best compact digital camera for your goals. In coming up with these recommendations for my friends, I looked carefully at Canon digital cameras (often the highest technology), Kodak digital cameras (great balance and simple user interfaces), Sony digital cameras (an alternative to Canon), and Olympus cameras, which can be good values and have some unique features such as weatherproofing.
Digital cameras fall into the following categories: [Each of these categories gets a separate section below. If you don't want to wade through this article, my current best recommendations for most people are the Fuji F30 (about $265; chunky but great for photos indoors without flash) and Olympus 720SW (about $280; waterproof and very compact)] Decide if you're buying a camera to carry with you all the time, and therefore it must be compact, or if you're buying a camera that you will take out when you are specifically engaged in a photographic project.
