Hey guys Happy Sunday!

I have a small icon I need to customize and upload to facebook in the following dimensions:
"The size of the image must be 111 x 74 pixels. File size limit 1 MB"

I think i read somewhere that by disabling anti-aliasing that images look sharper, is this true? and if not, given the specs I have shared, what would you recommend to get the sharpest quality at that scale? (without turning it into a science project...)

I have included a screenshot and a sample image like the one I will be using.

Thanks!

p.s. the example screenshot you see is not mine, just an example of scale concerning the thumbs.

On the contrary, you have to keep the anti-aliasing if you want something clean. On your image the text is at about the same size as normal text on a display (font size around 9 or 10) so if you want something clear and sharp, aim for fonts that are optimized for small sizes (Droid family for instance), and have good contrast between text and background).

Here's a quick experiment. Ultimately I think you should try a few methods and see which outcome you prefer:

Cubic/Sinc is the interpolation method. 1-step means scaling the image in one go from 1800 to 111 pixels and 3-step means scaling in 3 steps (first to 1237 wide, then 674 wide then 111 wide)
I use step scaling on my photographs, partly to annoy ofnuts ;) but mostly because I prefer the outcome and also it means I can apply post-scaling sharpening less aggressively.

I'm cool with any perversion as long as it stays in your home and is between consenting adults :)

Thanks paynekj, for the experiment example. I actually was gonna look further into those modes as well, but figured I start with the basic question first.

The 3 step sinc definitely has the greatest effect of clarity and sharpness
So how exactly would I be able to apply this again?

"I use step scaling on my photographs, partly to annoy ofnuts ;) but mostly because I prefer the outcome and also it means I can apply post-scaling sharpening less aggressively."



What's so wrong / "perverted" about his method he uses on his photographs ofnuts? (or is it more about his photographs being "perverted"?)
