10-12-11 – Infrastructure

Ennuipoet, I’m treating this as contest about Industrial Architecture. I assume that the intent is to photograph bridges, dams, water treatment plants, etc.

Hey ya’ll.

I have Farked for some time and as of Where the Wild Things Are just jumped into Farktography. I’m working up ideas for this contest one of which involves multiple exposures. I have searched the rules and read past threads on their philosophy and I agree but my question is this (and it probably belongs in its own topic):

Since multiple exposures “in camera” are alowed as one would have done on a negative, and Nikon DSLRs can perform this “in camera”, what are us Canon people to do? The mfg left out that feature.

Can we stack images as long as no other PS tricks are used ie tone mapping, exposure compensation from image to image so that film is still simulated, any other stipulations welcome. I just want the functionality.

if it’s truely done in camera, ie *set settings, click, change settings, click* then it’s kosher regardless of medium. Film actually gives a little bit more leeway, as you can put a registration mark on a roll, shoot it up, rewind it, and shoot it again.

using an “in-camera” function to fuse two previous exposures is not kosher.

as far as canons without in-camera multiple exposures, i developed a technique a couple years back to work with my older nikon. it only works with still life, but it works. set your camera on the lowest iso and tightest aperture. put your lens cap on. set exposure to bulb. tape down your shutter button, line up your shot, remove lenscap, count a few seconds, replace lenscap, line up second frame, remove lenscap, count a few seconds, replace lenscap, release shutter button. tada.

Thanks for the input and opinions. I was thinking like orionid mentioned “as you can put a registration mark on a roll, shoot it up, rewind it, and shoot it again” except a digital equivalent. I had considered Kestrana’s concern “you have the option in your PS program to vet which of your images is used and which looks better on top or bottom, the amount of opacity used” and its why I solicited “any other stipulations”. It’s becoming clear that this would require more legislation which seems to contradict your apparent principles of keeping it as simple as possible, which I am in favor of.

The idea of leaving the shutter open will not likely work as the setup time between exposures would cause too much sensor noise, at least it does on my 20D, maybe my new toy (7d) would do better. Anyways, I guess I’ll just stay away from the idea for now.

…set your camera on the lowest iso and tightest aperture. put your lens cap on. set exposure to bulb. tape down your shutter button, line up your shot, remove lenscap, count a few seconds, replace lenscap, line up second frame, remove lenscap, count a few seconds, replace lenscap, release shutter button. tada.

I did exactly this for one of my images in the “A Show of Hands” contest. It works, but it’s tricky to get right.

So, my Nikon has a multiple exposure setting in-camera (must be shot with RAW). I can’t currently use that, if I somehow figure out how I’d use it?

Just for clarity.

While I haven’t done anything much with the on-board stuff, there’s a freakin’ butt-load of software on-board. What’s in, what’s out?

(It won’t apply to this contest… I got some really good shots today of a train trestle over falls, and some other recent shots of stuff I’m fixin’ to use… just seems like the place to ask the question now that it’s being discussed).

Trains, train tracks, train yard = OK for this theme. Right?
