Focus Magic Software?

GerryL · 12-19-2009, 05:24 PM

I just found out that Adobe PhotoShop CS3 has something similar on its filters.
It's on the filters > sharpen > smart sharpen > then you can either correct gaussian blur, lens blur or motion blur..wherein you choose the angle at which to correct the motion blur.

Deconvolution, you say? In Raw Therapee (freeware) you have a choice of sharpening method; the usual unsharp mask and something called RL Deconvolution. Would this be similar to/same as focus magic?

RL Deconvolution is "Richardson-Lacy" Deconvolution most likely and is a different algorithm from FM's I think (differences between algorithms are about how to handle noise and what detailed form the out-of-focus disk assumes...eg. a gaussian disk is sometimes assumed like implied by Adobe.) Is it easy to use and successful? I vaguely recall thinking the learning curve on the Raw Therapee version might be steep.

PS A report/review of the Raw Therapee and other versions would be valuable.

Here's an example of FM in use as a plug-in for Paint shop pro (I think it'll do the same in Adobe, ie treat a selected area):

Kari, Lisa, Steve, and Anne are each out of focus by a different amount and can be individually corrected.

Here are comparisons from newarts post of the insect with PhotoShop Smart Sharpen.
I didn't overdo it and just kinda copied the resolution to newarts focus magic sample.

Dave,
I did not find that RawTherapee had a steep learning curve. Most of it is pretty straightforward. Some things you play with and observe the result. There is also a printable manual on-line. I think it's quite good for free software.

I downloaded and browsed the manual. You are right. It looks easy.

Regarding RT's deconvolution, can a selection be treated or must the whole image be deconvoluted?

I use RT v2.3 and it always works on the whole image with all operations.

Just download the latest version and have a play. It's free software.
