How do you Sharpen pictures already taken?
I made the jump from a super-zoom P&S (Sony DSC-H3) to a DSLR (Sony Alpha A350) and have been disappointed by the lack of sharpness on the A350 with the kit lens (18-70mm). The pictures are no where near as sharp as the P&S!.

I know I can increase the sharpness level on the A350 camera to +2 but how do I sharpen the jpegs already taken in Adobe Photoshop CS?.

Any tips in the right direction will be greatly appreciated and I'll then use the Help files in Photoshop. I just need an outline of the process to help get me started...

Go to Filter > Sharpen > Unsharp mask. This is the best sharpening tool..

As a starting point, try threshhold zero; radius 1 pixel; amount 100%.Try also threshold zero; radius 0.3 pixel; amount 300%..

If you over-do it you will get ugly artefacts so it is best used with care. If you are going to do sharpening in post-processing this way, turn the sharpening in camera to a minimum so that you don't end up sharpening an already sharpened image..

Google 'unsharp mask' and you will find more than you ever needed to know...Mike..

Well said  There's a million different ways to do it. May I add to the...google search list the following (perhaps not for a beginner, but pretty soon you might wanna take a look at them):.

"Lab sharpening""High Pass sharpening".

In csx or pe, for sharpening you can use the unsharp mask(but you wiould be changing settings depending on the picture scene type and intended use of the image file), or simply use auto sharpen. this applies a amount of sharpening depending on how much the pic needs. I use auto sharpen all the time. only on special use(astronomy,etc) and type pics do I change over and use the unsharp mask. I have gotten good success..

Note-you said that you running your camera's sharpening at +2. if you are going to sharpen in the computer anyway, I suggest backing down you camera sharpening to +1 or even 0. the pc will make up for any lack of sharpening later. and if you use auto sharpen it is a one click job...

Shoot RAW and do your sharpening in post. Purchase Photoshop. Use smart sharpening or unsharp mask. Use Edit - Fade to take away a little too much sharpening when you need to...

Before you over sharpen all of your images.go to a photo lab and make a large print of a few images directly from the camera with no post processing to see exactly what they look like first..

My guess is that you are looking at your 14 megapixel images on your computer and they don't look as sharp as your lower megapixel images, which is perfectly normal..

I ran in to this when I bought a 10 megapixel camera that I had a previous version of the same camera that was 4 megapixel, and the 10 megapixel images looks soft on the computer..

I was dumbfounded at first, and even put the new camera away for a few months and started using the old one again..

It wasn't until I made some blowups from the new camera that I realized it was the computer scrunching down a larger image to see the whole image on the screen that was giving that soft fuzzy look on the computer..

The enlargements from the straight-out-of-camera jpegs were razer sharp!.

You really don't need to shoot RAW to get sharp photos, either..
