Sorry, left out the B measurement. Here it is again, measurements are from the centre of the rod mount opening.

Here is a picture of the front of my Sinar F+ with the area I think you are talking about circled. From your drawing, I wasn't sure which dimension you needed and I am not familiar with the Norma. In...

With all this talk about tanks and racks, I thought I'd bring to attention this listing on Craigslist in Rhode Island :

I have no connection...

I don't know what you have for a darkroom, but I used to make prints by mounting the paper on the wall and using a right angle attachment under the enlarger lens. That was way back in my college...

That sounds like ye olde Quaker Oats box! Yes, I've done multiple pinholes with them, but the most fun was a cigarette box and a styrofoam burger box. I assiduously try not to make a "real" camera...

How about this - from a triple pinhole camera made from a 4x5 sheet film box. Film is 120, cut from the roll and taped on. 75335

I was in a pinch once and used a 150 Symmar S to make an 8x10 from a 4x5 and I can tell you that I never tried to do it again. An enlarging lens is superior as taking lenses are not optimised for the...

As other posters have said, many headlamps have a red light setting. However, some do not turn on in the red light mode when you first press the switch and might turn on in the high, white light...

I used to put my Gralab at about eye level, somewhere around the middle of the line of trays. That's about 2ft. or more from the developer tray. No problems at all with fogging. You can also face it...

I just checked a Symmar in a Synchro Compur shutter with a modern cable release and it worked fine. The same CR also works fine with Copal #1.

I think some of the older shutters might need a...

Welcome to LFP and a big Hello to Penang! What a surprise to find your post as I will be in Penang soon.

I'm coming late to this thread. Yes, I'd put in a good word for the AS220 darkrooms if getting to Providence isn't a big hassle for you.

AS220 is quite a resource. You can see other people's...

Here in one post are the instructions and a drawing of the acetate mask for the 6x7 format. You will have to make your own mask with the measurements as my drawing is not to scale.

I had...

Here are the measurements of the acetate that came with my 6x7 Calumet RF Holder. Please note that the line marking the 6x7 rectangle is 1/16" wide and the measurements are taken from the outside of...

Good idea, but with the acetate, you can also mark a matboard, tracing paper or whatever to insert over the groundglass as well. The acetate is just a guide.

I've measured my 6x7 acetate and...

On Monday, I'll scan and post the instructions here so that it's available for everyone.

In a little while (an hour or less), I'll post a drawing of the acetate with measurements. The 6x7...

I have the 6x7 version and it worked fine except for the uneven film frame separation. I haven't used it for a long time, but I don't remember overlaps in mine, just uneveness. I would also forget...

Yes, Deepak, it's not worth taking the risk if the bellows are in really bad shape. Are you in the UK? Here is a thread on LFP about replacement bellows in case you'd like to check alternatives in...

Before you buy a new set of bellows, I'd like to let you know that I've had good luck using black silicon caulk on enlarger bellows light leaks and pinholes in camera bellows. The caulk comes in...

Welcome Paul, really enjoyed your Flickr page! Would it be possible to put some titles or comments in English?

Good lord, you guys make me feel like a neanderthal! I'm still using a nearly 30-year old piece of black cloth with metal nuts sewn into the corners. It does slip off now and then, but since my...

I would also save the envelope that the film comes in (foil lined paper or plastic) and put the stack of film in there. It helps to add an extra measure of light tightness and also prevents film from...

I've used the tape sold specifically for holder hinges, gaffer's tape and black masking tape. Gaffer's tape worked very well but it's thickness might interfere with seating in some backs. Black...

Since there is quite a bit of interest in the Combi Plan tank, I looked for my original instruction sheet and the notes I wrote on it. Here are the developing times of some film and developer...

Like Ash said, try increasing dilution, development times and overfilling as much as you can.

The Yankee tank was the first "daylight" tank I used in trying to move away from open tray...

Other things to check for are your film holders and developing tank. You didn't say what kind of tank you are using, but the method of loading is something to check especially if it involves some...

Have you taken a look at Sprint chemistry?

http://www.sprintsystems.com/

Everything's liquid, dilution ratios in parts to make 10, eg. 1:9 where 1 part of concentrate is mixed with 9 parts of...

Thanks! I'll have to figure out how to stop time :)

I used a borrowed Harrison tent well more than ten years ago and loved it. However it was very expensive and I ended up buying a Photoflex tent that's kind of spherical. It wasn't as spacious but I...

How can I edit a post I've made?

I did a search and checked the FAQ and the FAQ states that there is an "Edit" button with a scissors icon. However, I just don't see it anywhere.

Is the edit...

Hello all,

I've been involved in photography since the early 1970's but come from a varied fine arts background. Having majored in photograhy in college, I worked commercially for many years but...

I've just signed up on the forum and am a very latecomer to this thread. I'd like to add that I've been using the HP Combi-Plan tank for many, many years. I've also used an 11x14 rotary drum with a...
