Default when unsharp isn't good enough anymore


The passed few months I have been actively working on improving the quality of my pictures I took with my digital (coolpix 990) and was continuously astonished about the possibilities of digital photo enhancement and of course PE2.
I assume it is the learning curve, but I believe I now start to see things clearer which results in a certain annoyance about the fact that the pictures I take are not as sharp as the the old fashioned ****ogue ones.
I can do some corrections with "unsharp" but doesn't seem to get that same crispness. What can I do to improve the sharpness of the images?

Robert, this is the way I do it. read about it somewhere on the internet and it works for me.

1-Duplicate layer
2-Filters>other(?)(Sorry, I use the Dutch version)>highlights; setting at about 10%
Enlarge to 100%
3-Layers>hard light>opacity. Opacity setting somewhere between 30 and 70%

This way you will be surprised about the sharpness of your images.

Hope this helps.

Leen, it's a good technique; went ahead with the translation just so
everyone would have the benefit of using it!

quality of my pictures<<

Robert,

Are you referring to improving pictures that you "take" also as well as the
ones you have taken and are enhancing?

If you are, I think the thing that will improve images in most cases is a
tri pod. If that is not available then propping yourself against a doorway,
across the trunk or hood of a car. Along the same thought line is using the
fastest shutter speed conditions allow and that will make it a bit easier to
get that focus. Of course there are some other variables like how much
depth of field you desire and then we need to look at aperture settings.
(Kodak has a set of four or five video tapes that cover a lot of ground
about taking photo's. Most larger libraries have it).

But (IMHO) Focus is probably the most difficult thing to try to put in to a
photo that does not have it. Lightness, contrast, even colors can be
enhanced and even changed fairly easy... but not focus.

If this is not the kind of thing you were asking for....sorry....just ignore
it

Pete

Leen,

I wll try what you suggested; see if it works which I hope.

Pete D; I refer to those pictures that are obviously sharp but when you look closer you find that the sharpness could be better. I use a tripod.

So far I use unsharp to enhance the
(un)sharpness, but also because digital images have a natural tendency to create "soft" images.

Thank you for your help and advice.

Robert

Robert, AFAIK you are suposed to do it after you decided which size you will print this image. I don't.
At my age I 've got the right to be a little pig headed. ;-)

Usually I apply this sharpening before applying soft focus or any other technique that influences the structure of the image, like adding grain etc. IMHO the image you wish to soften etc. should usually be with optimal sharpness before applying any "destructive" techniques.

In all other cases I use this sharpening after enhancing the image before I save it to a folder. This way I always have this sharpened image available in my archives before resizing it to the appropriate print size.

I always store my images in the maximum size before any upsampling or downsampling. Resizing is always done right before the printing stage.

This works for me.

Leen,

In order to compare both techniques I printed out two versions of the same picture. The image depicted a bundle of entangled weed along a meadow. (may be not the best of subjects to choose, but that in hindsight).
Funilly enough, the unsharp technique won as that picture showed more detail. The hard light version is probably better when the image itself is more staightforward?

I am aware that the PE techniques can only improve something that is there. Better lenses of course would give you quite a headstart.

Leen,

I'm a pretty straightforward user. All I want is a decent picture of a like wise quality. As a result I hardly use soft focus tools and use unsharp to take out the default of the digital camera.

Where ever I can I will enhance the quality of the original mainly by fiddling the levels or contrast/brightness tools.

Yep, I did slide the opacity slider between 30 and 70. Earlier on, in the comparison I referred to the printed end result of the two ways of sharpening.

I too tried a combination of hard light and unsharp. You want to be careful with this as too much easily creates an image of overexposure on the contrast i.e. it looks as if the image is painted.

I decided that the hard light sharpness is an alternative for unsharp but not necessarily a replacement.
Thank you for making me aware of this tool.

Robert

Leen and Chuck,
Thanks for passing this along. Works like a charm. Just to add my workflow:
I like to sharpen at the conclusion of all manipulations such as selection, cropping, etc. It is my understanding that this procedure, by and large, optimizes the process by minimizing further degredation.
