February '07 Photo Challenge - "Long Exposure" - Sponsored by joby.com

[Majik Imaje]

VPS = short exposures and they have what they call SHORT.

VPL = LONG exposures and they have a range for those..

At some point VPS ends and VPL starts..

I keep using this film as a reference only because .. "it is a PROFESSONAL film" with RANGES

NOW IF YOU look carefully at a Luna Pro light meter you see that the RANGE on THAT METER goes from 1/10,000 of a second to 8 hours

now .. define short ! ? or long ? the ONLY reference I know of.. (not that I consider my self of ANY authority .. NO! BUT it is the ONLY thing I can find. which gives a starting pont ! KODAK!

I guess I will have to find a data sheet on VPL to compare with the data sheet for VPS film

I will post the results when I find them!

I thought my arbitrary, personal opinion had some merit. A fraction of a second is short in common day terms.

However, to admit the other side has a point, one mans lifetime in the perspective of the age of the universe, is a blink of the eye. That's short. If you are 90, that's long in relative human terms.

The point is, in what context is short, short and long, long?

If you were taking a photo on glass plates, during the Civil War, a short exposure might be 10 seconds. When the early 35 mm cameras came out and one no longer needed a tripod to take a picture, 1/125th or 1/250th was short.

Anyway the month is almost over and then we can discuss what is ??? for next months March assignment. :thumbup:

Long or short is not only relative to the context but open to subjective arguments. Unless someone finds a book or article from a photo authority saying "long exposure is defined as..." we'll never have an absolute answer for the question.

The one I did find, says, "long exposure is defined as one second or over, or showing typical motion effects associated with a long exposure."

Kodak defines where VPS stops. and VPL begins..

I will do the research -=one cick=-

Re-search =two clicks.

that was a "joke"

let me find the data sheets..

I have stressed.. this at lease two / three times in this thread

Are Kodak's requirements considered valid? I can show motion in an image using 1/30 or higher. ?? Now I AM ALL CONFUSED. becuasethe bold quote you inserted, ? well now I can easily show motion @ 125 of a second very easily if something is coming towards me.

I will post Kodaks advice! and find what other informaton I can find. but VPS and VPL are the only films that I know of that are specificaly designed for a limited "RANGE" EV 1 ? EV 3 ? I WILL BE BACK.. in time for next months contest!

Alright, I'm sending mine in. Hopefully I won't have issues like I did in December, and hopefully this time mine isn't too "abstract" to get votes .

Darn I was going to write, Please Don't Enter. I need that tripod. :lmao:

This is the only photo BB where I've ever entered anything, and it's been great fun. The mix here and the general open and kind atmosphere makes it "the place". I plan on entering every month from now on. (and not winning anything)

Slow shutter almost shouts "abstract". Good luck.

Mmm....two more days, you say...

 

[GoM]

K....here's the thing...

I'm going out tonight to shoot for this, as I just borrowed a tripod now.

One problem is I may not get home before midnight....

I have my camera set to the proper date and time, so if I end up submitting it at, like, 1 AM, but the time is still in February...that cool?

As long as it comes in before I post them it's cool. I normally get a few in the morning following the deadline. Just make sure you complete the form properly when you send it. If you send it in a rush and miss something it might not be included.
