Hi all,

Being new to processing photos, just wondering if there is any trick to get the sharpness right on PS elements. Don’t know if I am missing the basics here.

Have just done some casual work group shots recently and was trying to post-process it on PSE 6. Did some sharpening using Adjust Sharpness – lens blur – and adjusting radius and threshold as required at 100% crop. For shots were there’s lots of detail I tend to keep the radius at around 1 and threshold between 90-100. For sharpening eyes etc. radius at 0.5 and threshold 150-200.

The end product looked okay on the screen, but when printed could see quite lots of noise on it even though the photos were shot at ISO 400. Further, the brightness and saturation were off which I can attribute to lack of my monitor being calibrated.

Have read few articles on internet to use Sharpness tool but I always seem to get it wrong. My question really is –

1.*How do I adjust sharpness on screen and make it look good on prints as well?

2.*Is there any guide to adjust brightness and saturation on screen and get this right on the prints without investing on an expensive calibrating tool?

3.*Finally, is there any way I can undo sharpness on the post-processed photo I have saved as I have done quite a lot of work with cloning on this and would hate doing it again. Was thinking of layer masking it with the original on top and post-processed on the bottom. I can then erase the bits where needed. However, I have cropped the post-processed photo so not sure if this would work?

I will really appreciate any inputs on this. Thanks in advance for your replies – Anand.
 
I can only answer with a view to Photoshop rather than Elements.

Sharpening, generally Amount is more than Radius which is more than Threshhold. Threshold "softens" the sharpening so I would very rarely have it more than one unless I wanted a particular effect.

There is a great link in this thread about sharpening -http://www.talkphotography.co.uk/forums/showthread.php?t=452482&highlight=sharpening

1. Generally you need to sharpen slightly more for print than you do for screen - if you are printing them yourself then experiment for different settings and see what works for you.

2. See 1 above. There are black to white diagrams available on the web where if you can see every shade your brightness might not be too far out but will let someone else confirm that.

3. Always sharpen on a separate layer - in fact I tend to end up with far too many layers as I find those more intuitive than using the history tool. The first thing I do when opening an image for editing is duplicate it so I have a clean one to work on/copy bits from, if I need it without opening it from scratch again. Not knowing how elements works I might even duplicate the document with all layers merged, sharpen that and then import it back into the original document and layer-mask/erase as necessary.
 
Thanks for a very detailed answer. Will have a look at that link tonight.

Will give this a go to see if it works (amount greater than radius which is greater than threshold). Great way to remember.
