I'm also relatively new to large format photography, and

I have a motto: sometimes it helps if you make an even

number of mistakes!

<p>

Example:

<p>

I was shooting a stream, had focused, metered (it was overcast

and not bright), set aperture and shutter speed, cocked the lens,

made sure the cable release wasn't in the picture (a specialty of

mine), closed the lens, inserted the film holder. All of this

took some time.

<p>

Just as I pressed the release, I noticed that I was standing in

bright sunshine. The sun had come out and my meter reading was

obsolete. Just as I was thinking that I had dreadfully overexposed

the film, I noticed with some relief that I had failed to pull the

dark slide out of the film holder!

Art Sands has used the Pentax 67 for B&W (see the

introduction on his web site)

http://www.artsandsphotography.com/

Unfortunately, it's not clear on his site which photos

were taken with the Pentax. (Although one might guess

from the dimensions of the pictures...)

Raymond,

<p>

I poked around a little bit using www.google.com, and

I think the photographer in question was Nicola Perscheid.

Apparently there is also a kind of large format lens named

after him. Do a search for Nicola Perscheid on www.google.com

and you may be able find out more.

<p>

I saw listed at least two photographers who were students of

his, and he was very active in the 1930's. If I had seen

a definitive biographical site, I would have give it here.

Lots of hits on his name in anthologies for sale, or listed

as teacher, or as a type of large format lens. (Even got

a shutterbug ad!)

<p>

Perhaps a German speaking large format photographer will

relieve our ignorance....

Richard (Ross),

<p>

I haven't used a 90mm lens with the Titan SF, so I can't

give you a definitive answer.

<p>

You might want to check out the review at www.walkercameras.com,

which claims that the camera worked well with a 65mm lens as

well as a 210mm lens. (Whether you want to believe the review

is another question.)

Hagai,

<p>

I use the Rodenstock Sironar-N 135mm lens with my Walker

Titan, and it is possible to close the camera with this lens

on. Feel feel to email me if you have more questions about

the Walker - like the other responder I think it's a great

camera....

<p>

See this thread (which I found by typeing "US fstops" into

a google search):

You can order manuals for most Pentax

products (at a cost of $4 I believe, if you're

in the USA). For details, see:

Mike,

<p>

I've used both the Pentax extension tubes and the macro bellows

with my old 1981 Pentax 6x7. You can get good results, but you're

not going to get much depth-of-field. (With both, you should

use stopped down metering.) If you're going to get either, I would

suggest the extension tubes - you can use them in the field. (But

the cost is damnable. Look for used sets on www.keh.com.)

<p>

For example, I have a stunning close-up of a damselfly, with

a turqoise-colored head, but you can see the grass stalk on which

it was perched slowly dissolving into the unfocussed background.

Depth-of-field was probably 1/4 of an inch.

<p>

I'm not familiar with any third party close-up lenses for this

camera.

<p>

Hope this helps, feel free to email further questions...

>...this may be cause i haven't looked in the right places.

Have you looked at www.calphoto.com?

Someone referred to this useful site in the original Q&A:

http://bobatkins.photo.net/info/faq30/flashfaq.htm

Hope it helps....

While surfing the web, I came across this useful site:

http://travel.boston.com/newengland/foliage

The brusque answer: go to www.google.com and search for "foliage report". I saw hits for Vermont, Maine, and New Hampshire (www.

whitemtn.org - which was mentioned on photo.net before).

More personal answer: I live in north central Massachusetts, and

some individual trees are already turning bright red/yellow. Every

Saturday I go to a local pond to shoot my annual "fall foliage

relected in the water" shot; as of last Saturday only a very

few trees had turned color.
