Default Sharpening issues

I think I have my OMD set to low noise control etc.. With my old DSLR I had a preset USM I used and with the OMD I lowered it by quite a bit. I just printed a few images yesterday and they seem odd. Of course the three 60D images were the same, it could have just been the quick printer messing it up. Online the images look fine, but I do print my photos for home normally to 16x20. I worry they'll look over sharpened. I'm not good at photoshop, just the basics, so what can be done? Should I sharpen less? What do you guys use for a somewhat standard setting with USM? Should I maybe not sharpen at all?

Well, an example would go a long way in letting us help you.

You mention that your camera is set for low noise control, so presumably you are shooting JPEGs. What level of in-camera sharpening have you set?

Sample won't work since digitally they look fine, it's the print which unless you come over I can't show you.

I'm not sure how to change the sharpening in camera? I have it set to jpeg super fine, sorry but my crappy laptop doesn't like RAW and for now I want to get to used to things with the camera before I attempt RAW.

What about the print looks odd? If they're over sharpened they'll have halos around any high contrast edges.

You can change the Sharpness in the camera from the Super Control Panel (the little S in a circle).

For post process I like to use local contrast enhancement with the Unsharp Mask Filter set to 20%, Radius 30, Threshold 0. For less effect I use 12, 66, 0, or 5, 100, 0.

take a good test file and print the file without any editing, then print it with your normal edits. that will help to see if it is the camera's settings or an action you are taking.

also consider taking the same image with your 60D and your EM5 then pixel peep it (look at them both at 100%). edit the 60d image as you like, look at it at 100%. next do your post processing on the EM5 image and check it at 100%.

You will find one of the following:

1. your camera is set up to sharpen too much
2. your "default" 60d PP doesn't work for the EM5's sensor, lenses and jpg engine
3. your camera is sharpening the file too much then you are pp it with even farther sharpening

Ok I see the little S it's at zero. What do people here keep it at? If you're using USM at 20% then I'm going way too high! Maybe I'll try lowering that first and keep the camera at zero. For the 60D I would use it between 90-130 depending on the shot. I think it's set to 76ish right now. Next time I'm in PS I'll lower it then print and see what happens.

I don't have the 60D any more. But I'll use an old photo and try to retake it in a similar way and see how things look. I normally don't pixel peep unless I'm testing a new lens then I'll look real quick. But I do crop. I worry that with my lack of sharpening technique I won't be able to do that much.


Thanks so much everyone! I have so much to learn with PPing and with a new camera it's making it harder! I miss dark rooms!! ha ha!

The file will show us a great deal--the printer is just an output device. You do need to post a 100% crop with the entire image would give us a better idea what you are seeing. You would be surprised what you can see in a crop and how that would relate to a print.

Written descriptions are useless.

Unsharp masking should always be done at 100%.
