Hi,

I have a number 8 Century studio camera. Huge beast.... The bellows seem to be what I think is called Mackintosh cloth. It is a rubberised fabric - not very thin by bellows standards but it...

Hi,

I've an old battered MPP Mark III.

The rangefinder seems to work well, but is not linked to the bed. There is an arm, ending in a small chrome bearing. There is a bracket coming out the the...

Hi,

I've got a few rolls of this.

Thing is, when I googled for the description of 2645 - I can't find any mention of it anywhere at all. :confused:

I've scrubbed the kodak site and all the...

Sorry - bit late to reply but I have in the past tried making screens by sandblasting.

It is far too coarse - giving a very rough and crunchy screen. There is something called 'bead-blasting' -...

There are lots of cleaning methods that can work - and some good advice here.

Golden rules are:
1. First remove dust and loose particles with a blower brush etc. I use a soft paintbrush after...

I've just made a whole set of lens boards for my Speed Graphic. I would post you a picture - but Flickr has announced that as I've exceeded 200 pics, my earlier pictures are now held to ransom until...

Ok, thanks for the tip! ;)

The secret to removing the ring is to get a decent grip with a good quality spanner wrench of the correct size and shape. The thing you really want to avoid is attacking it with something that...

Hi,

I often clean optics as part of my day job. There are lots of different methods that work, here are my thoughts:

The biggest problem with cleaning a lens is scratching it in the process....

I'll look forward to that!

Where will it be announced, do you have a website or something?

I wholeheartedly agree that very early lenses seem to be almost fungus proof. I rescued a Ross Rapid Rectilinear from a shed with a leaky roof that could have been there for many decades.... It was...

I, too, have never seen a fungal attack on the very early lenses, with their flint and crown glass (Rapid Rectilinears and Petzvals and such). It may happen, but I've never seen it myself, even...

Hi,

I have a Dallmeyer lens of similar vintage and uncoated, which also had a fungus problem (Mines a Serrac)

There are several different types of fungus, some worse than others. The worse...

How good are you with wiring up simple circuits? ;)

The overall conclusion of this thread might be that the audio program 'Audacity' - combined with a little bit of basic electronics and mounting...

I don't think it is necessary to test each combination in sequence one at a time. I was just pointing out the complications of the early shutter. One problem, of course, is that because the curtain...

I think that is a very valid thing to do - at the end of the exercise it is the actual photographic exposure on the film that really matters - not the theoretically calculated exposure based on a...

Rick, in response to your question about the output voltage being high when the shutter is open or low when the shutter is open - the cascode #1 works one way and the cascode #2 circuits works the...

I had a quote from them about 6 weeks ago. Maybe you are ringing the old number and emailing the old email? (I hope so, they are a company I'd really hate to disappear!!!)

Here's a cut and paste...

Ok, here's a few circuits as promised.

I'm aiming this post at photographers who have had a go, or might have a go, at the simple home made sound card shutter tester. Those who have a bit of...

Hi again,

My earlier (long) post about the shortcomings of the phototransistor refer to the very simple common emitter configuration using a battery, bulb and one resistor a recommended in several...

OK... I did study electronics at university - but that was 1979 :eek:
I think I am a bit rusty, so bear with me. I'll try and keep this very simple, partly because I am aware that this is a...

Actually, I was refering to myself...
My objective certainly was to finally get the Speed Graphic I bought 10 years ago serviced and working so I could take pictures. I have a nasty habit of getting...

It's been around 28 degrees C in the UK for the last week or so... (sorry, don't know what that is in F. Not very hot by Bangkok standards, I'm sure!)

That means mid 30s in my darkroom (in the...

Sure!

Do you want an in depth guide to servicing the shutter?

Or building a shutter speed tester?

Or testing the shutter speed?

Or testing the shutter speed tester?

I've just made a new screen for my Speed Graphic using Ian's suggestions on APUG.

I've made many before, using car engine-valve paste. OK... but a bit coarse. Using silicon carbide grit produced...

Hi,

This is my first post here. Actually, my reason for finding and joining the site is because I have just stripped and rebuilt a Speed graphic. I tested the shutter and found it to be all over...
