We have been discussing a few technical topics on the blog in the last few articles, with pixels and how the sensor works and before I let your brains relax I want to show you what the inside of your camera looks like and how it works.
So those are the bits that make up the [...]
Here is a list of every single photography related abbreviation that I could think of. If I have left anything off feel free to let me know.
This should help you understand any terminology when using or shopping for your camera equipment.
A ~ DEP ~ Automatic Depth of Field
AE ~ Automatic Exposure
AEB ~ Auto~Exposure Bracketing
AF ~ [...]
Understanding how the innards of your camera function can help you understand how or why your photo is coming out under or overexposed on any given day.
You sensor is the most important part of your camera…yes I know – the sensor would be nothing without the rest of the team – but your sensor is [...]
You find yourself in the midst of choosing a new camera and you are being bombarded with information about all sorts of features and accessories for the various cameras. How many buyers decide on their ‘choice-camera’ is by the amount of megapixels it has. (or MP for short)
While this is by far not the only [...]
In this article we want to share with you what we know about Noise, the dreaded splatter on an otherwise beautiful image. We believe that the most efficient way to reduce noise in your photography is to first understand it. I believe the famous quote is ‘know your enemy’.
What is Noise?
Noise is to a photograph [...]
The Refractor Design
Refractors are what the average person identifies with the word “telescope”, a long, thin tube where light passes in a straight line from the front objective lens directly to the eyepiece at the opposite end of the tube. Heavier, longer and bulkier than equivalent aperture Newtonian designs and catadioptrics such as the Cassegrain [...]
We, at SACamera, have put together what we think is the most basic way of explaining the most important camera settings to get your snapping happy. This very basic mini-lesson is aimed at beginners. If you know very little (or nothing at all) about cameras – take some time to read through this and by [...]
Four Thirds is a system pioneered by Olympus and Kodak and designed exclusively for digital SLR cameras. It exists as an open standard and is supported by a consortium of manufacturers including: Olympus, Sigma, Panasonic, Leica, Sanyo and Fujifilm.
The Four Thirds Standard Defined
As a mechanical standard, Four Thirds uses a sensor size roughly half that [...]
The zone system was first developed in the early 1940’s by Ansel Adams, a reknown landscape photographer. The zone system is a method for determining optimal exposure by visualizing the final result of the photograph and then placing your exposure to achieve it.
The zone system starts at pure black and then increases exposure by 1 [...]
Lens Reviews often provide the most accurate and comparable idea of how sharp lenses are since they tend to provide standardised data on lens characteristics. Specific distortion percentages, measurements on the exact EV loss due to vignetting and sharpness ‘blur’ units make it easy to get an idea of how the lens is likely to perform and how it compares to other lenses.
Autofocus sensors work by measuring the difference in contrast across the sensor. A sharp point of focus will have a strong edge contrast, with the edge weakening as it becomes more blurry. This is the principle on which the autofocus processor determines that maximum sharpness has been reached.
