Three Hour Petroglyph Exposure by tcore Three Hour Petroglyph Exposure by tcore
Full View Please.

This three hour exposure was taken in the outskirts of Bishop, California. The petroglyphs were most likely done by Owens Valley Paiute, or the Mono Lake Paiute Indians from 1650-1800, before the arrival of the whites.

All prints, custom matting and framing available for purchase at [link]

I am listed as one of three featured photographers on the site. Thank you for viewing my work!

very nice, a question though. How do you calculate a 3hour exposure?

I have a remote for my camera. Manually, I open the shutter, watch the clock, and return in pitch black to use the remote from a distance to close the shutter. Thanks for your interest. Tyler core.

wow that is a cool image. Do you use photoshop to get rid of the noise in your night shots?

No, my homie helped me on photoshop (NARMANSK8) but the noise was not there. the temperature was extremely cold, so i dont know how to explain it. every shot since has had a grainey look to it! haha.

Oh, I thought maybe you had a trick lol. Maybe cold weather is better because there is less moisture in the air.

This is absolutely amazing man, I don't think I've ever seen a three-hour exposure. Nevertheless, it's quite an interesting phenomenon. Very alien, very surreal. Well composed, well executed, I love it.

Thats quite mystical. The star trails add a sense of magic to the entire shot, and the petroglyphs are special to begin with. I'm sorry I never made it there when I lived in Cali.
How'd you light the landscape? That doesn't look possible with just the on camera flash.
I didn't know the XT could handle a 3 hour exposure, or anything that long, so cleanly.
Beautiful work.

Thank you very much for your comments! Well, yes, the rebel XT can hold just under a three-hour charge in it's battery...the only problem is that you can not review your work, or continue...so what you shoot is what you get. The petroglyphs are lit by one flash directly from my Canon. It is not as visible here, but my partner and I encountered a little bit of a amber color exposure residue on the corners of the picture upon rendering them... (this is a mystery to me, and is all i know about that!). But all in all, the exposure took three hours, and killed my battery completely. Thank you for looking and taking the time to comment!

Not vignette - it's probably due to heat build up in the sensor/electronics. Always a problem with digital and long exposures.

which, in the color corrected version I uploaded, you'll see it turns violet - same as an IR/heat source would.

I think that what you're talking about there would be vignetting - basically just the darkening of the corners of the image.
If you do lots of long exposures like these, have you thought about buying the battery grip?

Pretty stunning image. Especially if you clean up the levels and the red channel to bring up the local contrast.

Really well shot.

Thank you very much for looking. Do you think that the contrast is too red, or not red enough? Thanks. Core

I think a quick color correction would bring the contrast and color balance closer to this:

Thank you very much! It is a long, scary drive home after such a long exposure. The battery would not show the only picture in the memory card... and I had to wait another hour for the camera to charge! Thanks for taking the time to look! Tyler Core

Now this is pretty wild looking, at first I have to admit I was having trouble figuring out the composition, but then I got it. 3 HR exposure! Your battery musta hated you! lol

Fantastic shot! I've seen a lot of star trail photos, but never anything like this. There's hardly any noise or hot pixels in it either. Did you use in-camera noise removal or shoot a black frame to go with it, or was the quality just this good right from the camera?

tcore Featured By Owner Feb 6, 2007   Photographer
This qualty, believe it or not...came straight from the camera!. The three hour exposures are very difficult to eliminate noise, but this crisp night just allowed perfect conditions for such a long exposure. Thank you for looking my friend. -Tyler Core [link]

Ahh, I guess the cold temperatures would have helped. Apparently hot pixels form more readily with warmer temperatures. I'll have to remember to try my next star trails shot on a cold night.

Great image. Two ways of viewing the past. Actually three is you count the photo. A photo is a frozen instant of time, the petroglyphs are a picture of an era and the movement of the universe is record of all time.

Three hours is quite a time to wait. Your moon shot is just stunning! You used a telescope, obviously (or perhaps a very good telephoto lense). I would like to start taking photos of the moon. Any tips?

Well, actually the planet is moving. I set the exposure time for three hours, and lit the petroglyphs with one flash source. what you are seeing behind the stars, is the movement we experience on earth. A trip huh? If you point directly at the north star, you will get beautiful circle tracers from the stars. Thank you for looking. Ill be checking out your work often. T Core
