Digital Camera Sensor Sizes: How it Influences Your Photography

Digital Camera Sensor Sizes: How it Influences Your Photography
This article aims to address the question: how does your digital camera's sensor size influence different types of photography? Your choice of sensor size is analogous to choosing between 35 mm, medium format and large format film cameras — with a few notable differences unique to digital technology. Much confusion often arises on this topic because there are both so many different size options, and so many trade-offs relating to depth of field, image noise, diffraction, cost and size/weight. Background reading on this topic can be found in the tutorial on digital camera sensors. Sensor sizes currently have many possibilities, depending on their use, price point and desired portability. The relative size for many of these is shown below: Canon's 1Ds/5D and Nikon D3 series are the most common full frame sensors. Camera phones and other compact cameras use sensor sizes in the range of ~1/4" to 2/3". The crop factor is the sensor's diagonal size compared to a full-frame 35 mm sensor.

Debunking the myth that focal length affects perspective + how to actually do it In this tutorial we show you how to take charge of perspective by using different viewpoints and camera angles to radically alter the look and feel of your images. It’s often said that lenses change the perspective of your shots, with wide-angle lenses exaggerating perspective and telephoto lenses compressing it. That’s not actually the case. While it’s true that you need to change the focal length of your lens to achieve different types of images, the lens doesn’t actually affect the perspective of your images. All the lens does is determine how much, or little, of the subject you include in your image.

Brooke's Sensors page There are a number of technologies that are used to sense magnetic fields. I have also included some places where magnetic fields are used like in MRI, NMR, particle accelerators that use super conducting magnets. 1 Oersted = 79.58 Ampere-Turns/Meter 1 nano tesla = 10 micro Oe = 1 Gamma 1 Tesla = 10,000 Gauss Papers about Magnetism - Journal of Magnetism and Magnetic Materials - For over 100 years, Elsevier Science has been dedicated to facilitating the exchange of information. The Magnetic Measurements Handbook - NASA has a series of web pages devoted to magnetic topics called: The Great Magnet, the Earth & A Millennium of Geomagnetism Earth's Magnetic Field Magnetic Field Calculator - need Lat, Lon, elevation, can choose WWM2005 or IRGF 10 models.

Aperture Diffraction Limits - Lonestardigital.com Apertures, Pixel Sizes, and Diffraction Limits. Contrary to popular belief, smaller lens apertures (with their greater depth of field) don't necessarily result in sharper pictures. When the negative effects of aperture diffraction begin to outweigh the positive effects of increased depth of field, sharpness falls off and fuzziness sets in. Smaller apertures also cause slower shutter speeds, often requiring higher ISO settings to make a shot. Understanding how aperture diffraction works and relating how diffraction applies to your camera will help you to take sharper pictures. Cambridge in Colour has an outstanding tutorial & essay about diffraction limited photography.

Getting started with 500px - Jason Waltman Photography by jason on | 50 Comments 500px is an online photo sharing community. It’s similar to the popular website flickr, but designed by photographers, for photographers to share only their best work. 500px has about 500 times fewer registered users than flickr—but in my opinion, that’s a good thing. Sharp IR Rangers Information Introduction Sharp infrared detectors and rangers boast a small package, very low power consumption and a variety of output options. In order to maximize each sensor's potential, it is important to understand how these types of IR sensors work, their effective ranges, and how to interface to them.

Digital Camera Diffraction – Resolution, Color & Micro-Contrast The exact value of the diffraction-limited aperture is often a contentious topic amongst photographers. Some might claim it's at f/11 for a given digital camera, while others will insist that it's closer to f/16, for example. While the precise f-stop doesn't really matter, it's good to clarify why there's so many opinions, and how these differences might translate into how your photograph actually appears. This article is intended as an addendum to the earlier tutorial on diffraction in photography. Knowing the diffraction limit requires knowing how much detail a camera could resolve under ideal circumstances.

Blog / Tutorial: Time Stack Today I’d like to introduce the brilliant Matt Molloy, photography enthusiast and budding professional. He’s the author of those amazing impressionist inspired photos. So many people have asked how to do this technique, and he’s been gracious enough to share it here with us! Image sensor format Comparative dimensions of sensor sizes In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular camera.
