HDR Images of moving objects - How ?

[Goochie]

As a novice, compared to many on here, I've just started taking an interest in creating some HDR images. I know they're a bit of a Marmite subject but I really like them - particularly the really extreme examples.

My non-SLR Canon can do bracketing and save RAW files so I have two options; 1) take several images using bracketing or 2) save a RAW file and work from that.

However, there is something that I've yet to work out.

How do people create HDR images of moving objects? clouds, animals etc. My camera will take about 3 pictures per second when bracketing so obviously this will give me problems when trying to create an HDR. Even slow moving clouds cause me problems.

So how do you do it?

EDIT: For example, this would be quite difficult to shoot in 3 frames!

Pseudo HDR:

Take a single image and generate the multiple images you need for the HDR through something like Photoshop.

Take one RAW image and process it twice, ie for highlights and shadows. Then blend together using a method of your choice - I do it a lot for wedding photos that need high DR.

there are also cameras out there now that take upto 3 exposures at the same time, I believe fuji do this

what methods of blending do you use simpo?

Some HDR progs let you process a single frame. You can't get such extreme results but it gives them a certain 'feel'

This is one frame HDR'd

For simple areas an eraser of varying opacity, or for more complex scenes a layer mask method I found on the internet. I don't understand layer masks at all but have learned it off by heart and it usually works. The idea is to end up with a realistic image so that nobody knows what's been done, it just has proper detail in the highlights and shadows. As you can imagine, wedding dresses are the usual culprit, also white collars. I also use it to help even out the inverse square effect of flash lighting, bringing down the foreground and lightening the background - useful for large rooms. Nobody knows the extra work that's gone in, but the images look better

I'd say that's more like soft focus - have you tried it with a portrait?

I'm normally a fan of your work, Steve. But that makes my eyes go funny! As said, it looks more soft-focus than HDR.

Chaps! - not a fav... just showing as an example of 'one shot HDR' - and on top of that I did soft focus.

another HDR from one shot here (Well received on here, but I don't like it - just an example showing that you don't 'need' 3 shots to get the effect:

Just cheat with the exposures rather than take them in camera? Or are you a purist

Take original shot into lightroom, adjust exposure to -4, -3, -2, -1, 0, 1, 2 saving each shot as you go. Open in hdr software of choice and adjust to suit!

Hmm - interesting concept. More info, anyone?

Almost exactly what I was thinking!

So how do you do it?

Photomatix will allow copies of the same photo to be added, it recognises that they are the same and will ask if you would like to change / graduate the exposure and by what degree.

These wereeach made from one picture, duplicated to make 3 diferent files that were loaded into photomatix and 1stop variance was made. ie -1, 0, +1. (hope that helps)

cant remember the article (I linked it in Carters recent thread I think) but either fuji were employing a large bit processor/sensor or were taking multiple exposure readings and combining at the same time. It was a fuji hdr camera

That's HDR for you! As I say... I don't like the image!

I used a single image to create this as the shot was in a hotel with limited light. I stepped it up and down from memory 2 stops or maybe even three and then imported it into Photomatix.

The Sony alpha a550 also has an HDR mode, it needs to drop by at least £150 though.

Any camera that has a Fuji Super CCD EXR chip in it can generate photos that have a wider dynamic range than most other digital cameras on the market.
