Jagged pictures after resizing down?

Mar 25, 2013 11:51 PM

Tags: #cs4 #photoshop

I never encounter this problem before, but suddenly my photoshop acts like this.

I resized down my HD pictures (2k pixels) to 500px and this is the result. It looks like raw .. looks like a big picture resized down in browser without actually rasterizing it (??)

I want the smooth looking back, but how to do that (pic below, 2nd pic)?

for example I want to achieve this result (below pic 2nd pic, smooth looking. I resized using another program and it's smooth looking, when i resize the same picture down in PS, it doesnt look smooth.)

Help is greatly appreciated. thanks!

    Which Image Interpolation Method did you use (see the dropdown menu at the bottom of the Image Size dialog)?

    To expand on what c.pfaffenbichler just said, Photoshop's default resampling algorithm USED to be Bicubic, which balances sharpness nicely against smoothness.

     

    For some reason they made the default "Bicubic Automatic" in Photoshop CS6, which ham-handedly applies Unsharp Mask - this may STILL leave you with an image that's crunchier than you like. 

     

    It's as though Adobe believes that someone somewhere actually thinks that's a better algorithm.  Trouble is, no one - NO ONE - I've ever met thinks so.  Not even beginner users appear to like the extent to which it oversharpens.

     

    My suggestion is to change it to "Bicubic".
