TMAX 100 in XTOL 1:3 develope for 17 minunts (but do a test for developing times for yourself)

I have a bottle of DDX that has been open since last fall and I have 4 rolls of Delta 3200 to develop. Ilford mentions a shelf life of 6 months for half full bottles. Could any one tell me from...

SA 72 on Toyo AII

Hello every one and happy new year. I was wondering if any one uses a recessed lens board with this combination. I use this lens on a flat board on my AII and I do get the back...

Dear Emre:

This is off topic but since I know you use a SA 72 on a Toyo AII I am curious if you use this lens on a recessed lens board. I use this lens on a flat board on my AII but want to know...

Bill:

Remember that depth of focus increases at close ups so you don’t really need a precision back for this purpose. Take a look at this post see what Julio Fernandez has written at the end:...

One thing that is responsible for a pleasing bokeh is a round iris when the lens is stopped down. Nevertheless I am aware that some lens designs do posses a good bokeh despite having an edgy iris...

Greetings from a Viennese café!

If you get N for HP5 in Rodinal 1:50 for 10 minutes with 2 inversions every minute in combi plan tank, or in my case probably N-1/2 since I have always used ISO 400 emulsions in high contrast scenes,...

Bobby:

The denser the selenium solution the faster you reach your maximum D max. Once you have reached this point it looks like selenium does not affect the prints any more. With warm tone papers...

Have heard a lot about this combination and want to try it. My tests for HP5 4x5 in ID11 1:1 developed in Combi plan T (with inversion agitation once every minute) has been slightly more than ISO...

One more tip:

The ferry that takes you in the Grand Canal and to the 3 islands travel 24 hours long so do take advantage of this to photograph places like San Marco at night.

No problem taking a large format in Venice. Italians love artists and respect them a lot. You can set up your tripod almost any where. I am based in Vienna and travel to Venice very often. I...

Iran is my country of birth but I haven’t seen it for the past 16 years so i cant tell you much. You may want to email “Abbas” an Iranian Magnum photographer living in Paris who has been...

Mark does this manufacturer have a website?

many thanks

ciao tutti

Juergen:

How is the color cast of your 65 f4 Nikkor? Is it cold (neutral) like Rodenstocks, or warm like Schneiders? Could you comment on this please?

Many thanks

Mark:

Stop your EL Nikkor down to mid apertures and you will get a more even illumination although still not perfect. In real practice though you should only notice the edge light fall off if your...

Just a quick question Paul: when you have the back mounted on the camera what is the difference in length between your camera’s original ground glass and the ground glass of the back. Could you...

Paul you may take a look at this page too: http://www.kgcphoto.com/Reviews_&_Tutorials/shen-hao_6x17_back.htm

cheers

Paul check this post here : http://largeformatphotography.info/lfforum/topic/500542.html and thank you for your input Travis.

Dave, what is the weight of this back, i have heard it is heavy.

PS: I just found this page: http://www.kgcphoto.com/Reviews_&_Tutorials/shen-hao_6x17_back.htm

Will really appreciate those who have purchased the Shen Hau’s 6x17 roll film back in the past few months to write a note on its performance. Since most of us will be using extreme wide angle lenses...

Hi Paul:

I just checked Robert white’s page looks like they don’t have the Hhen Hau roll film back in their stock. There are people however in this forum who have ordered products from Shen Hau...

Large format lens designers seem to have more freedom to control distortion due to the size of large format cameras compared to an SLR camera. That is why we don’t see the typical distorted look of a...

Ernst try this: www.clydebutcher.com

Randy are you sure you are using Mini super ball plus (Balmu) and not super ball (Ballo)? According to this pdf file: http://www.foba.ch/pdf/FOBA_tripod_heads.pdf / http://www.foba.ch/pdf/index.htm...

Does any one use a Foba mini super ball head with a field camera like a Toyo AII with sometimes a relatively heavy optic on? Can the head handle this weight? Or is it just at its limits?

Francesco: What emulsion do you use that yellow filter on, could you mention this please?

cheers

By the way who is this Japanese manufacturer producing the 6x17 roll film back designed for 4x5 cameras? Never heard of them before.

Yes this is confusing. The 6x17 back illustrated on http://www.shen-hao.com looks very much like the Kangtai KT617 http://www.ktcamera.com/kt617/KT617-eng.htm looks like they have changed its look...

Travis:

I have also realised the difference on the Shen Hao 6x17 back illustrated on their web site compared to what Kerry has used (day1 or what ever) and I am also keen on this back. But I guess...

X-Tol at 1:3 for 17 minutes at 20°c tames down the highlights of TMX. 1:3 dilutions yields full ISO 100 speed but don’t expect more than 5 stops of effective dynamic range from this emulsion. I...

Pete & Francesco:

How fragile is Efke PL 100s emulsion? Will adding hardener to fix help prevent damage to the emulsion when wet? I develop my 4x5 sheet films in a Combi Plan T tank using...

Ciao Francesco. Could you post the address of this Azo forum please. i couldnt find it in search.

cheers

Hello Armin. You are talking about the Schneider 47 on a flat lens board am I right?

What is the widest lens you use on a Sinar F2 using the standard 455.36 wide angle bellows with no recessed board. I have heard form people who use a 65 lens comfortably despite Sinar recommending...

William: Boss screens are not really brighter but they are clearly sharper and have a lot more contrast than my original Sinar f2 screen.

cheers
