Resolution Question

"Hillbilly" wrote in message

Is there any way, with any program where you can zoom in on a tiny part of the photo and get it crystal clear. You see them do that on TV and I now TV is not reality, but I was curious if there really is a way to continually zoom in on a area and enhance it like they do in some of these crime shows.

Thanks

As you say T V and CSI are not reality.

No. It is not possible from normal Camera images, and even less possible from CCTV images.

Having said that, pictures from Military Satellites, do get enlarged and enhanced to a remarkable degree, but who knows how much any of that activity or equipment actually costs. That is a different sort of unreality.

You can’t create detail that is not there. On the other hand if you have a photo that has a great deal of detail you can zoom in a lot and still have it show sharp.

Some programs can do some good guessing as to what might be there, but it can only do that based on what was really captured in the original.

What exactly were you wanting to do?

I got this picture of a bull elk that was about 100 yards away. Was shooting with a 100-300 zoom at max zoom. Using a Canon 20D. The photo is perfect in everyway, Just wanted to crop it and only get the Elk. When I enlarge the image with the Elk only, the elk is not so clear anymore. Kind of fuzzy. I enhanced as much as I can, but the crispness and clarity is just not the same. I was hoping that there is some way to crop a small section of a photo and get a decent result without it been postage stamp size.

Thanks

It is impossible to get a cropping and zooming a picture. But the effects can be minimized by doing the enlargement in steps. Instead of increasing the size of your crop 100%, go in small increments until you get to the required size. But you will still get a picture lower in clarity compared to one that captured the elk as it was.

Hope I was clear in the explanation.

If your question had been theoretical, I would have pointed you to http://www.gigapxl.org/ There is an interesting example where they zoom multiple times and still get a relatively clear picture. But it’s a gigapixel camera 😉

Hi there.

As I said earlier what they do on the TV is impossible.

But you can try the re-sampling in steps.

Increase the resolution by less than 10%, and repeat the process until you get the image size you want.

Then try sharpening by making a duplicate layer.

On this new layer, apply the "High Pass" filter at about 10%. Then apply "Hard Light" in Blending Drop down box. Then set Opacity to about 50%.

Check on the sharpening effect by making the new layer visible and invisable, and adjust the level of sharpening by increasing or decreasing the new layer’s Opacity.

That’s why the ‘pros’ spend many-thousands of dollars for the "big lenses."

Thanks Roy, I will try it.
