15 minute exposure

Took this shot in Grand Central Terminal. Not sure whether I like the color version better or the B&W.

Thoughts on the shot itself/color preference?

Lots of ghosting, people walking around, is that what you were going for?

Yep. lol

Heh, reminded me of this...

What do you do for 15 minutes while you're waiting? The waiting in that environment would drive me crazy!

Yea it sucked lol I kinda just stood there and was on my iPhone. I had my camera on my gorilla pod and security said that I was okay but just to make sure I stayed with it so it didn't fall over the edge, so I was holding the camera strap with one hand and just standing there trying to entertain myself. It was worth it though

I think the black and white one looks a little underexposed and the colour too orange - I'd suggest brightening up the black and white one and playing around with the colour balance of the first. Great shot though

I like the colour one by far. Has a nice warm light to it. I find B&W only turn out well when there's a lot of contrast, or if certain colours are distracting from the picture.

is that one single exposure? for 15 mins, really? why/how isn't it completely blown out from the light?

< ---- still a noob.

Based on the EXIF information the ISO set was at 100, and the aperture set at f/8.0. EXIF data is information that the camera embeds into every picture your camera takes.

Exposure is really based on 3 settings, ISO, aperture, and shutter speed. Altering any one of them changes how much light is let into the camera (sensor).

Below are my best laymen's term definitions to try and describe them to a noob :

Shutter speed: how long the shutter is open; during this amount of time light is allowed to reach the sensor. The longer the shutter is open the more light that is let in.

Aperture: the size of the hole created by the lens to let light in - similar to your pupil; the higher the number (e.g. f/22) the smaller the hole, the smaller the number (e.g. f/2.8) the larger the opening. A larger opening would allow more light in. Aperture (along with a few other factors) also effects depth of field.

ISO: The sensitivity of the sensor. I usually like to use this analogy ... think of it as the number of light catchers. The higher the number the more 'catchers' you have to receive light (or number of bees to collect honey). Thus, a higher, such as 1600, number means that more light will be 'caught' by the sensor.

More regarding EXIF data...

For the top image posted above, the EXIF data should be found here (assuming the link works for everyone):

You can easily get to this data from any image posted on Flickr (unless it has been stripped away) by clicking on the image posted, then click on the make/model of the camera on the right side of the page. This should open the page that lists the EXIF data.

Ghosts of people passed....

I like the color version - nice idea and well executed with just a hint of human presence.

yeah, my bad. I'm not that much of a noob, but thanks for taking the time to explain.

at any setting with that much light, i'm wondering how a 15 min exposure wouldn't be completely blown out.

Heh. Yeah... usually when I read the word noob, I think in terms of someone who picked up a DSLR a week ago and has learned how to turn it on

Just remember P is for Professional! as seen here (the good parts start around 1:30 or so): http://www.youtube.com​/watch?v=-S3NFW2c7hA

Did you try any other exposure times? I ask because I would have gone for something shorter. To me it's just a little too ghostly.

In any case, although it makes for an even longer wait, I would suggest trying different times just so you can see what they look like. If they end up being less than 5 minutes, then the scene can look different depending on how people walk by and thus multiple exposures are also a good idea.
