Leaving the shutter open ?

[btcole333]

I am new to DPS . I got a Canon 7d for x-mas and I am fairly new to photography and have a lot to learn. I am having toruble leaving the shutter open for a period of time. I can do it but I have to hold the shutter button down . Is there a way to just push the button and have it stay open for a period of time with out having to hold it down? Thanks and would appreciate some help .

A locking remote controller may solve the problem..

This should do the trick.

There is not only a matter of keep the shutter "open", there is a couple of concepts you should be aware of too: lens aperture, ISO and shutter speed. These 3 concepts are the main variables in taking photographs, because that will affect the exposure (amount of light into the sensor).

Now, once you have understood those three concepts, you can experiment with your camera. Take a look around the forum, there is a lot of tutorials and information that will for sure help you out to understand the exposure concept.

Talkin about your question: your shutter speed is to high, you are using the "bulb" feature to control the shutter speed, that is why you should keep the shutter pressed all the time. Depending on your camera capability, you can have a different shutter speeds maybe up to 30" or more.

I am aware of lens apeture, ISO and shutter speed and I know they are some of the main variables in taking photos. Yes, I am new to this camera ( its a 7 D ) and photography . I just want to know if you can leave the shutter open, without holding the button down the whole time. I know I have a lot to learn with my new camera and its going to be lots of fun and I am about to start taking some classes to help me learn more then just the basics. I will start putting some of my photos on here and ya'll can pick them apart and help me out and yes I am from Texas . Go Long Horns !

If you end up needing more than your camera has built in, EBay has a good selection of remote shutter releases that can hold it open indefinitely in BULB mode. I picked one up there for under $20 but it took a while to get since it came from China.

There's always the wired release option as well but as far as I know that still requires holding a button the whole time.

So i guess i need to get a remote . Thank you . Rapid City must be cold. Tell Barb and Jeff I said hi. He used to bartend in Texas. Not to say you know them, but thanks for you help .

Any scenario that requires blub exposures is very rare and certainly not beginner teritory. It might help if you explain what you are trying to take a picture of as there may be a better way.

For exposures of 30s or more (whcih is what bulb is for) it needs to be very dark.

Hey Fletch thanks for responding . I got some really cool pictures of lighting with my other camera (Panasonic DMC-FZ28) . I just left the shutter open for 30 seconds and got some amazing shots. I know I am way above my head right now with my new camera just thought someone might be able to help me out a little .
