A phenomena that exhibits or arises due to signal interference as signals of similar frequency interact in a destructive manner. Common examples in photography are "jaggies" along the edges of strait or lightly curved lines, and "moire" when high frequency patterns are resolved by a sensor without ...
According to http://mansurovs.com/nikon-d800-vs-d800e the D800E differs from the D800 in that one of the layers of the filter reverses the effect of the initial low-pass filter. How does this work? ...
These two cameras have been announced by Nikon just this month, and they appear to be quite the same. However, getting the D800E instead of the D800 costs around $300 more. I don't know why that is ...
I understand the purpose of the anti-aliasing (AA) filter is to prevent moire. When digital cameras first emerged an AA filter was necessary to creat enough blur to prevent moire patterns. At that ...
One of the allegedly big advantages of Fujifilm X-Pro1 is its new color filter array layout, which does not require anti-aliasing filter in front of it. In theory, this could mean notable improvement ...
The commonly stated trade-off for using an anti-alias filter or not is that it diminishes the risk of moire while also reducing potential sharpness. This is what I have seen myself and in many online ...
What is Aliasing and Anti-Aliasing? Is it a bad thing to have in an image? If so how to avoid it? If you can describe your answer using examples then that would be great.
It seems as though it is becoming more common for new digital cameras to come without low-pass filters. I learned quite a bit from reading the excellent answer here: What is the difference between the ...
When I compare images that I shoot with my 30D against images shot with a friend's 600D, the 600D consistently produces sharper images than my 30D. This is true even when the images are viewed at the ...
What is meant by area sampling in graphics ? I know it is an anti aliasing technique.
Do either the Canon PowerShot SD880 IS or the S100 have anti-aliasing filters? If so, has Canon announced any P&S model(s) without OLPFs?
