Daniel Madsen Posted January 31, 2006 Share Posted January 31, 2006 You have all seen the results of shooting fine line detail (especially horizontal lines), like a striped shirt. The image is very distorted- zig zaggy. I know there is a special term for this type of distortion but I can't think of it. Any help?? Link to comment Share on other sites More sharing options...
Mitch Gross Posted January 31, 2006 Share Posted January 31, 2006 That is a moire pattern, and is referred to as Aliasing. When it is more minor, such as the edge of a sidewalk bouncing back and forth between two lines in seperate fields of interlaced video, it is commonly referred to as "twitter," although I don't know if this is considered a proper technical term.

Mitch Gross Posted February 1, 2006 Share Posted February 1, 2006 Moire is the resulting pattern. Aliasing is what causes it. Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted February 1, 2006 Premium Member Share Posted February 1, 2006 Moire is the resulting pattern. Aliasing is what causes it. There is also the "toothcomb" or "sawtooth" effect on the edges of moving objects when fields are combined into frames. Link to comment Share on other sites More sharing options...
