Bulb Photography Tutorial

This is a tutorial on how to take nightscapes using bulb. In this video I describe how I capture star trails, how to set up your camera and how to light subjects in your image.

I have a Canon T3 Rebel EOS and I've done an exposure of 27 minutes and i always get the image to turn out really white even when the ISO setting is on 100-200.

Any advice will be helpful!

God bless,

@guitargluv your overexposing the image , the exposure needs to be shorter, probably a lot shorter.

Hi Conor, does long exposure wont destroy the sensor? what aperture do you usually use on startrails?

[QQQQcon]

@dokgold you would want the sensor to get really hot, but I have done 30 to an hour exposures with no problem, although those are best done when it is cold outside to keep noise down.

Hey Conor....I recently got my d7k and have been experimenting with long exposure. I did a test last night at about 4 minutes, iso 100, d-lighting off, LENR off, and lens cap on....there were TONS of hot pixels visible at 100% crop. I noticed LENR works well, but taking 40min for a 20min picture doesn't seem practical, especially if I want to take seamless star trails over a few hours. Is this normal? I tried to link to an example, but it wouldn't let me. Thanks!

@outdoorsman567 seems a bit excessive to see so much noise after only four min. but it is not unusual to see noise after 4 min.

@919664 that is ridiculous, the d3100 has image quality that destroys the d5000, has video, has a much better autofocus system, much better iso range and more. dont kid yourself.

[QQQQcon]

@4FRONTFilms oh ok, you keep telling yourself that. I am not going to argue with people who have no idea what they are talking about.

@guitargluv Make sure that your aperture is at the highest it can go. (e.g. f22 of f36) Then take the pic, but it will take a long time. Check out my photography on my page!

3200 isn't 32x faster, more like 5x. Double the ISO, and you get one stop more sensitivity. 50-100-200-400-800-1600-3200-6­400-12800-25600-51200-102400-2­04800. the last one is only 12x brighter than the first, not 4096x. lol. nice vid anw

@guitargluv I got mine for about £4, in the region of $7-8.

If you don't want to spend any money at all and you have a Canon DSLR Magic Lantern has it built it, along with an Intervalometer, best part is it is free. One thing i would say is to read up and watch alot of tuts for installing it, as it can damage the camera, but done right it is a fantastic tool to have.

How do you control the noise in your photos, because they look very nice?

I really like the bit of math at the end!

keep it up

Your math is off regarding metering at ISO 3200 and then shooting at ISO 100. Rather than dividing, you should be calculating stops. 100, 200, 400, 800, 1600, 3200. 6 stops. That way, you can calculate your shutter speed accordingly. Multiplying your shutter speed won't work.
