Need Help with Simulated Motion Blur

04/02/2004 10:54:44 AM · #1

I have a product shot that I am working on, in which I have a shot of a model and a product. The product must be sharp, but they want me to simulate movement in the model. I have tried PS's Motion Blur, but find that the results are not to my liking.

Any help would be great. Are there any good PS actions that would help create the streaking required to simulate motion.

Here is the image I am using:

Here is the PSed version using motion blur: //mariomelillo.com/gallery/Products/Walking_Cooler_1_small

Rather than apply motion blur to the entire image, just select the right half of the image, running along the line of both woman and suitcase. Then apply motion blur to that selected area. Your motion blur will eek into your subjects and create motion streaks without actually blurring them.

Any significant motion blur you apply to the person will look unnatural, IMO, because her feet are both planted. there can be no motion of her legs while that is true. Also, any motion of her body would be followed by the cooler.
I would suggest including motion by blurring the free arm. Here's my take on it...

I duplicated the arm on another layer, used radial blur and then blended it back in.

mmm this is what i would do, but with more care.

Some motion blur

a bit more motion blur

and a graphicy one ;)

One thing to keep in mind is that in this situation certain parts of her will be more in motion than other parts. Her lower legs and feet should have less exagerated motion than her upper body since her feet are planted. The hand gripping the bag should not be in motion either since the bag isn't in motion.

To get a truly realistic effect you're probably going to have to experiment with some masking and varying levels of blurring and/or duplicating the image and using transparent versions of the image. I'm at work with no PS right now so I can't really suggest any techniques.

Good luck.

Here is my take on it, different amounts and angles of motion blur applied to different parts of the body, depending on the speed of movement (between 2 and 5 pixels on your download file) and 1 pixel applied to total body.

Stretching the front leg, lifting the back leg, lifting the foot, not at the toes but at the back, just starting to move, and swinging the arm , plus slight movement in the rest of the body.

I dont have much experience with this but I played around with PSP-7 and took the draw selection tool and added some motion blur, I did it pretty quickly and no doubt more time spent would result in a better and neater result

Wow! I go away for lunch, and i get all this help. Gotta love DPC!

Thanks for all the input. You guys are right. I have to think about which parts would be in movement in this step, and only apply it to the appropriate parts. Definitively the arm swinging, perhaps some movement in the upper body, and maybe just a little on the back leg.

I guess I'll have to research how to apply different masks and stuff. Wheres the best place to learn how to do that? I think I'll try Lunimous Landscape. They often have some good tutorials.

JP, how did you create the effect on the first one?

This is a surprisingly complex kinematic system! And bare eye will spot urealness of any blur if it does not follow the right amounts and angles.

First of all, the decision has to be made: is it a motion within a long exposure or a stop motion by rear-synch flash? In the first case I would stick to motion blur applied creatively and in the second case there is another scenario.

I don't like motion blur effect much so I would offer my scenario.

1. create the image of 1/10 sec before the shot (better have two-sequence shots but I assume the work has to be done with a given). For that you need to choose axis of rotation for each part and displacement of each. For example, this pose is the final of a step forward with a little body rotation counterclock. Also, assuming that the case did not roll forward - it had to tilt forward. That's easy: select it and rotate clockwise 2~5 deg around the contact point of the weel with the floor. This will define bodu displacement. The left leg has to "step" back on the heel, it's toe does not move. The right leg - is opposite - the heel stays as the rotation axis and the toe goes up, the knee goes back. Once the legs are done, move and rotate the body back and squeeze it horizontally a bit to simulate the rotation around verical axis. The last is the right hand - for the balance it might have appeared completely from behind of the body :-(

2. I am not sure that there is a plugin which could morph one into another but I know of a standalone ones (e.g. this one). You can use the morph tool to create several inter steps.

3. Now put the new images into the layers with diminishing opacity underneath the existing and then blend them together manually bluring edges.

Anyways, an interesting exersise even if it might be not worth doing it in particular case.
