motion blur - Treefrog in motion

Postby _Paz_ » Fri May 09, 2014 9:48 am

When i wanted him/her to be still !

I like this shot except the setting isn't good. Here you can see what the texture of his back should look like.

Image

I'd like to do a Ken Burns pan through this shot for my video/ painting. Froggie didn't stay here long, I'm not sure if he was landing or taking off again.

Image

Here is a 100% crop of the frog. In closeup view it is easy to see the lines of white that are bumps on his back in motion. I've tried using PSCS6 motion blur to see if I could settle him down but I don't see any difference when I move the compass direction bar. Any thoughts on a better way to fix this other than 'painting' in each spot? I'll already have to do that when I paint him. ugh

thanks,

Well, remember that, if you're adding the photo to a video, you will be working in video resolution -- so even if your original photo shows great detail, you're only going to get, at best, 1920x1080 in your video -- or, if it's video for a DVD or standard definition video, 720x480 pixels.

So there's no point in painting in detail that won't actually show up on your finished video anyway.

BTW, have you tried running an Unsharp Mask on the wider shot of the frog? It may bring out more detail in the original photo.

Thanks Steve. I hadn't considered that there would be a difference in resolution nor have I ever taken a higher def still into a video.

Which do you think would be more likely to happen? The blur won't show? Or it will look even worse?

I use a high def monitor. Not sure I would see things the way the majority of people would see it. (I sometimes visit my local library to get an idea.)

A tip on how to figure out how to set the needle for motion blur:

Looks as if the angle indicator should be IN LINE with the motion you want to cancel.

I'd do some experimenting, Paz, and see what effects what.

But just be aware in the meantime that video resolution is never going to be as fine as photographic resolution.

Is this something like what you're trying to do?

Those do look good, Ron. I posted mine with no sharpening. What settings did you use?

What I'm trying to do is get rid of the bluish-white-grey streaks that run diagonally from upper left to lower right on a portion of the frog's back. Easy to see in the full resolution link I posted above... not so easy in the reduced file... and obviously that's what Steve was trying to tell me without using the word "obsessive" which I so richly deserve.

Here is a full resolution crop (small enough to not break forum formatting) of the offending area where froggie's body is in greatest motion:

Image

If I were painting him in pastel, I'd probably want to include the streaks, perhaps emphasize them to indicate his motion. But in a tight, botanical illustration watercolor format, I'd like to resolve his streaks into bumps. The best I've been able to do with Adobe's Motion Blur fix is this, which looks awful.

Image

I'm not terribly skilled in Photoshop although I have been using it for basics for many years. And I've never been able to get Motion Blur to work for me. I was hoping someone would know how to fix the streaks on his back, and around the eye bumps. There is another blurred area on the lower right leg which is moving in a different motion altogether. That one doesn't bother me. Just the streaks on the highlighted portion of the back and head.

I use GIMP and I now only use high pass filters to sharpen which uses grey scale sharpening. GIMP also has a motion blur type filter but the results look just like yours. I don't think you are going to get those blurred whites spots to look as spots again without degrading the photo.

Here's another Utah photo using GIMP and high pass sharpening:

Is that a coyote chasing a road runner, Ron?

No, that's me chasing myself looking for the restroom because I forgot to go before I left home.

The frog photo is a problem because there are 3 different blurs present: camera shake, out of focus blur, and subject motion. The shake reduction filter is only designed to reduce minor camera shake. Never the less, it can help some.

The default blur trace is too large and in the wrong place. Reduce the size and move it over the frog's head. You'll need to increase the smoothing some from the default. A single blur trace isn't sufficient on this photo. You can add additional blur traces to correct other zones. Here's a sample with 4 blur traces. You can see the dots where the blur traces are centered:

Not perfect by a long shot, but sharper than the original. It will need a little cleanup. Instead of simply running the filter on the original layer, duplicate the image layer and run the filter on the duplicate layer. That will allow you to add a layer mask afterwards and use a soft low opacity black brush on the mask to blend in with the original layer to hide some of the artifacts. You could also use a clone or healing brush for cleanup.

What if you had that full resolution crop to work with? How would that look on that photo? If you could clear that one up I'd be interested to try it myself. I'm not sure how I could translate the steps into GIMP lingo but I'd try.
