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 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.
