Re: [am-photo] Digest Number 43
- I found some pictures from my old site on my laptop. I thought I'd just add them... http://www.egroups.com/files/am-photo/Tanis/
I normally use 100 or 400, personally never used 800... it is just a bit TOO grainy for my likings. CESPUGLIO.jpg is a good example of a typical use of 400.
I took MENTORELLA.jpg pic at 5 am... All I used was a UV filter. All you have to remember is to keep the smallest exposure possible to avoid the reciprocity (I wonder if that's the english word) effect on the film. Smallest doesn't necessarily mean smal: my smallest exposure was 1/30, I had to use a tripod for the whole set.

do you suggest 400 or are we already talking 800?
i think there are more effects and plays with light during those times too... but the photos never turn out the way i hope they do...

- That file was inspiring! Just what I needed after a day of Senior
I've been talked into a Nigerian wedding (last one was so-o-o-o long!)
the one thing I love is the clothing. I was thinking of bringing my
35 for some shots for me, the studio never even shows me the work!
Not sure how kosher that idea is, but I'd really lie some "keepers".
- Tanis, from About.com on reciprocity:
Is this word you were looking for?
> Films differ in their responses to long exposures, but all sufferfrom an effect known as reciprocity failure. The Law of Reciprocity
in photography is what allows us to make use of the idea of film
speed; basically it says that exposure depends only on the total
amount of light hitting the film and that it is immaterial if this is
delivered in a short exposure at wide aperture - such as 1/1000 at
f2 - or a longer exposure at a smaller aperture - such as 1/60 at f8.
For most films this can be relied on when exposures are between
perhaps ¼ and 1/1000 seconds, but outside this range it will start
With black and white films, this simply means that a longer exposure
will be required at low light levels than would otherwise be the
case; with colour film it also results in shifts in colour as the
different emulsion layers have different reciprocity characteristics.
These will differ from emulsion to emulsion, but there are often
fairly clear trends by manufacturer. Some night photographers prefer
Fuji emulsions (finding they tend to give cooler results as exposure
increases) to Kodak (which they say get warmer) but it is a matter of
personal choice. Some films are definitely less affected than others.
