Hi Johannes!

As you are from Sweden, it will be easy for you to find a Plaubel camera with old but very good german optic. I'm personally own Plaubel-Peco Universal 8*10 with perfect (really like it alot) Schneider-Kreutznach Symmar 300/5,6(500/12). It's not a field kamera, but it's foldable in other manner. In "folded" position this cam is about 50*40*15cm.

The lens are convertible - field of view is equivalent to about 50(80)mm at 35mm film.

first of all thank you all for responses!<br>

it's clear now it was albumen print. so it will be possible to get this kind of paper for printing.<br>

very interesting was information about negative retouching.<br>

less clear up to now what kind of lighting was used. natural or artifical? <br>

looking into the eyes of this genleman you could see fat white almost horisontal lines. these are reflections of a light source, i suppose. <br>

was it a large window, line of lamps with reflestors or moving light source. we may only guess...

my question is about the history of photography. i would like to

shoot studio portraits with "look&feel" of the ones made within

stated period of time. <br>

i'm planing to use large format camera for these pics.

please share your knowleges on:

<ul>

<li>lighting techniques and equipment </li>

<li>typical film sensitivities</li>

<li>typical exposure times</li>

</ul>

any related information is also highly apericated.

here is an exsample of what i would like to get as final result.<div></div>

i'm back =)

J Pryszmont: your full res. scan looks great. with fine details and absolutely no grain (i can't find any). yes, it's promising and if you calculate... oh, got... i got 460,8MP form 8*10. sounds very impressive as for me.

Joe VanCleave: in your experiments what sensivity you get on pre-flashed Arista .EDU RC grade 2 paper? was it asa 12 (6*2)?

salesman in photo store told me that grade0 paper is less sensitive and therefor less contrast than grade5. up to now i have only hans-on experiense with grade2 paper. was he right? if yes how much differs sensivity from one to another grade? i'v found some info at ilford site but can't interpret it right.

could somebody help?

huw finney: very interesting. the questions are how big will be light fall with such filter and what sensivity this kind of paper has. do you know it?

J Pryszmont: i tryed resolutin up to 1200dpi on my scanner. on the highest res. snanner noise is extremely visible(very cheap scanner).

i assume it's possible scan also at 2400dpi with very little or no paper grane. i think so because lower film sensivity results smaller grain. and sensivity of the paper is really low. so, you could try it and say if it's true for paper too.

in this topic i want to share my experience of making pics with large

format camera and photopaper as medium.

first of all i want to answer the question "why".

large format photo process is rather expensive as a hobby. it's time

consuming too. and if you would like to do some digital post

processing on 8*10 negative you will need a very special filmscanner.

my aim was to minimise time of getting results and to reduce costs.

equipment

Camera: Plaubel Universal 8x10

Lens: Schneider-Kreuznach Symmar 5,6/300

Paper:Ilford Ilfospeed RC Deluxe Paper (is2)

Scanner: mustek 1200 usb

after some experients i have found an easy way to do large format

pics within as litte as 1-2 hrs. from setting up equipment to getting

a print.

now i'm using medium contrast ilford paper as light sensitive medium.

it has sensitivity of asa 5 or 6.

surely i got to use long exposures or extremely bright light source.

for my home studio shots i'v used direct flash light of my sunpak

auto 36 fd on its full power from about 1 meter. the aperture was

fully open.

another issue is that paper has extremely high contrast compared to

film. so, it feets best for low contrast light situations such as

shooting in shadow or with artificial light.

how it works...

1. put a sheet of photo paper in film cassete

2. take a picture

3. develop the paper-negative

4. dry it

5. scan it (scanned at 600dpi 10*8 negative gives you about

30megapixel grainfree picture)

6. invert and correct in photoshop

7. print it

that's all

you can take a look at some studio photos made with this technology.

greets.
