Combining multiple exposures in advanced editing?

Unfortunately, I am pretty sure that you can't.

AlexSaberi got burned by this rule with an entry featuring star trails and a swan... Here it is in the Masters FS II:

Is this the technique you're talking about?

Edit to find entry.

That's quite a leap. I think that was because the swan wasn't in all of the frames. Nothing to do with flash.

Bingo. The flash itself should be fine IMO (I think we've validated such an image).

I see I am mistaken. Thanks for the clarification. Now only if some ideas would come to me ;).

It would be interesting to have another "Inside looking out" challenge now that the rules allow for multiple exposures. This is a challenge where that technique would very be helpful.

what you describe here should be legal but I think it would be up to SC to determain it, unlike the swan in Alex's picture , The detail of the inside of the tunnel is always in place however if it is not showing in 9 frames but appears in 1 they might rule it the same way they did with the swan shot. perhaps use flash on a few frames starting with lowest power and then increase slightly for others.

Thanks for the responses.

What I was getting at was for instance if you were to take a picture inside a tunnel. By using a flash on one of the exposures you would be able to light up the inside of the tunnel and at the same time have the correct exposure for everything outside the tunnel.

This shot would for example have been interesting to try with this technique:

I'm interested in this technique. Could someone elaborate on the benefits and other applications a little more. I've taken to shooting some multiple exposures, etc. but nothing too advanced.

In the swan picture below, do I have this correct. Only one exposure has the swan in it and the swan is taken with flash, but none of the other exposures are.

Wouldn't this technique eliminate ghosting and blurring of a moving person in HDR images? For instance, shooting an alley with only frame having a walking person in it, then waiting til they leave to take the rest of the exposures?

I shot some inlet picks at night that were wonderful, but I could never get a boat in the image tack sharp. So, the the images have always been a little disappointing. IN this case, I could have accomplished a better result had I used flash in one of the exposures. Correct?

Nah... only the lighting changed, not the scene itself. If there had been a pelican flying by in one frame, or the left half was daylight and the right half a starry night, THEN the scene would change and it would be DQ'd. A static scene where the photographer is dealing with exposure or DOF is the purpose of the multiple exposure allowance, and that's fine.

That would be DQ'd for the same reason as the swan. You can't just pick a frame or frames with the object/pose/expression you want in it. Stick to static scenes or shoot a series quick enough to keep movement to a minimum (blowing leaves, slight movement in clouds, etc.).

Thats what I thought too. But I also thought Alex's swan should have been legal, So being on that 50/50 balance I wasn't sure which side of the rope to fall off. I am going to attempt a shot like this for a challenge eventually and want to be sure I do not do it illegally.

I have always had this weird question that I wanted to ask:

Advanced rules, ten captures,

so does that mean we can take a capture a day as long as no swans pop in to visit??

For the most part, no... all the captures have to be within the challenge dates. You could do it for a month-long Free Study, but there's no real advantage to doing so unless the scene changes (time lapse, change of season or weather), and that would be DQ'd.

now I have a question. kind of reverse of topic, If I take 10 shots and flash 1 of them, in the one I flash a person happens to walk into the frame. Can I legally clone that person out of that picture and use that frame in my stack of 10?

02/10/2009 10:58:15 AM · #18

You're overthinking it. Just take another picture without the person and use that.
