Resizing the Right Way?
I don’t seem to know how to resize the right way. I often end up with jaggies and other artefacts around details. Take a look at this pic for what I’m talking about. Note the artefacts around the text.
So what’s the secret here? A magic $20 plugin? Selective blurring and sharpening at various stages. Not that long ago I started downsizing in steps using a PS action. It doesn’t seem to make that much difference. Kate’s old glasses seemed to present a particular challenge in this arena nearly always rendering with some jaggies at one particularly part of the curve. See below.

I know the root of the problem has something to do with having sufficient pixels to render curves or lines of particular angles. But am I approaching that threshold that often? And if I am, what am I doing differently from all the other photographers that don’t seem to have this problem as often? This isn’t the end of the world, but it’s kind of annoying. I often find myself backing off the sharpening to reduce the apparent jaggies. I’m asking too much?
Are you sharpening, resizing, and then sharpening?
Yeah. I sharpen the full size image at 100-150%, Radius 1, Threshold 1. Resize. Then sharpen at 75%, Radisu 5, Threshold 1.
Bicubic sharper for the second resize or regular bicubic? Email me a full res copy of this image and that one in the beginning of the post, I’m curious about something…
For downsizing, I find bilinear to be the best. Sharpening before is not a good idea, it makes the task harder. Bicubic sharper was designed for downsizing as well but I find it to hard most of the times. Bicubic smoother could be used but will make it softer than bilinear. Bicubic smoother was designed to enlarge.
Stephane, thanks for the tip. I’ll give bilinear a try, and I’ll rethink my sharpening routine.
