A to Z Challenge: J is for Jaggies
Welcome to today’s post for the great Blogging A to Z Challenge!
Today is J is for Jaggies.
Jaggies? What, you say??? Hey, J was hard for me. Then I saw the term “jaggies” and thought, hey, that’s a fun word!
So, according to Vincent Bockaert (http://www.dpreview.com/glossary/digital-imaging/jaggies), “[h]ardly a technical term, jaggies refer to the visible “steps” of diagonal lines or edges in a digital image. Also referred to as “aliasing“, these steps are simply a consequence of the regular, square layout of a pixel. ”
To me, aliased images so appear “jagged”, and anti-aliased images are smoother. For digital photography, seeing jaggies means seeing more pixels. The higher the resolution of your picture, the more pixels it has, and the smoother it will appear.
From what I have read (on http://www.picturecorrect.com/tips/aliasing-in-digital-photography-explained/ and http://www.dpreview.com/glossary/digital-imaging/jaggies), you really notice jaggies when you blow up your images. For example, take a picture like this:
I’m going to focus in on this:
And with a little cropping and blowing up of the image, I get this: Jaggies!
Phew! That was not easy to do… Hopefully tomorrow’s prompt will be easier!
