Moving object in HDR??

[Jahalu]

Hello guys!!!

So I just got a question....how can i make HDR of moving object? i.e: waving flag, or moving car?

I need different exposure shots of that object, right? But how can i do it when the object is moving??

Is it possible to take one shot in RAW and than in PP change the exposure???

Or how is it done???

Thank you for you answers!!

you can do a pseudo HDR - photomatix with one RAW file, try it out, bet you will like it.

Well...so if'll do 6 different images with different exposure from RAW and i'll do the HDR from it is it the same as i'd take 6 jpg pictures and merge them together and will do HDR????

Is it the same or completely different???

It's not the same as bracketing, but you can't HDR a moving object as it will be blurry. I do a lot of pseudo HDR with photomatix, you would be surprised how well it can turn out.

First off of either 3,5 or 7 images are used to make HDR pics. there is no 6 image unless you decide not to use one of the 7 images, why I don't know. To do an PHDR from a single image for a moving object, capture the scene with a single raw file at 0ev, from that file make a -2.-1,0,=1,+2 OR -1,0,+1 exposures. Then process it the same way as if you bracketed them with the camera. The merging and processing is the same the only thing that is different if how you got the multilpe exposure of that image, you either made them from a single raw file or the camera captured them. HDR is made from images bracketed throught the camera and psuedo HDR or PHDR is images made from a single raw file, know the difference between the two. I hope this helps you out. Good luck. ;)

p.s. The only difference I noticed between HDr and PHDR is that with the same setting in photomatix used to tone map both HDR & PHDR was that the colors in the PHDR were slightly different then the actual HDR image. That was the only noticeable difference between the two.

Yea I haven't seen any real difference with pseudo hdr vs. taking the single raw file and doing the exposure thing manually. I use to do that, but I'm generally happy with the single file. I do a lot of walking when I am out, so carry equipment around all the time isn't really the thing I want to be doing. I should get one of those bags that allows you to attach a monopod or tripod to it.

Another difficult question guys...... So if i want to do panorama of a beach and there are some waves and they moving i should do all panorama in PHDR????

or if i want to do just panorama (no HDR) of the beach how should i do it that the waves are looking realistic and not badly stitched together???

thanks ;)

with VERY VERY advanced photoshop skills!!!

or just move back and get a wider shot and crop to look like a pano :)

Well here is a pano I did in Monterey California. used photomerge in CS3.

Do this. First do a normal pano of the beach and 0ev. Then redo the pano but this time taking 3 bracketed shots through the camera. When you do the PP, stitch the normal pano together. Then for the HDR pano merge and tone map each set of images by them selves, then stitch together. But remember to keep the same setting in the tone mapping the exact same do not change anything so all the portions look the same. If the HDR pano does not work out the way you want, then take the normal pano that you stichted and do a PHDR out of it. make 2 other exposures off of the stichted image then merge. I would shoot the beach a tad on the wide side so that the waves look like they are crashing normal.

Here is a HDR pano I did.

okay bu t how did u do the waves??? because on every shot are the waves different....so if you need 3 shots of the ocean you got 3 different pictures with different position of the waves.......so how to do it???????

[S.E.V.]

I didn't do anything but take the three shots used to make the pano. I leveled the tri-pod then the ballhead then panned from left to right 3 shots. You can see in the third shot that the whole wave is in the shot.

Here are the three shots, try it for yourself

Here is an image I created using a single raw, created multiple exposures and combined in photomatix... obviously there is movement in the image but by shooting a single raw it turned out pretty good IMHO. :)

super job theague

thanks a lot :)

Very nice indeed, I think the only advantage of doing multiple exposures from a single raw file is that the foliage would not be so soft looking, all three exposures will have the foliage in the exact same place in the shot..
