The process time shouldn't change with film speed but the replenishment rate of the chemistry might.

The process time shouldn't change with film speed but the replenishment rate of the chemistry might.
I've used TMX with plain ID-11 but can't recall the exposure/development details - I'd have to look at my notes. In post-exposure Ctein recommended TMX and provided the details for a colour neutral...
When doing 8x10 Ilfochromes in an 8x10 cibachrome drum the cpm-1m paper I used wouldn't bend to the curve of the drum. It's more of a problem with smaller prints than larger ones.
One thing I should add is that the Cibachrome drums might require more chemistry than an equivalent sized Jobo drum as they don't have the ridges you slide the paper into (at least mine don't) which...
For Ilfochrome the minimums were 75ml for 8x10, 150ml for 11x14 and 360ml for 16x20 drums. These were doubled for the transparency materials. There's no mention of 4x6 in my booklet. You'd need to...
My 4x5 enlarger won't handle anything larger than a 150mm lens due to the 72mm or larger lens thread size.
I would not blindly install a 250W globe. Although the voltage is the same it will draw 25% more current which may overload wiring, connectors and/or the transformer. Power dissipation is...
For those using 75mm lenses with a 12mm recessed board, once focussed on infinity (and after removing the 75mm lens so you don't accidently hit the ground glass) do you still have enough room to move...
Sorry, no specific experience however my 45AII which lists similar limitations has some pretty squashed bellows with a 90mm lens on a flat lensboard. I suspect in order to use a 65mm lens you'd need...
PS ignore my previous message if you're using a 5x7 or bigger enlarger. :)
One other thing to check is to ensure that you can get (or have made) and can fit a lensboard which will take the lens. Most 180mm lenses have a larger mount size (typically 72mm) than their 4x5...
I think the film notches are okay. Looks like there's been some distortion due to a wide angle lens as the top right negative looks more like a 4x5 sheet than the bottom two. There's certainly an...
I've found a Lee 87 IR filter works fine with Maco 820c both Aura and non-Aura. For the Lee system there's also a 100mm Cokin resin 89B (Z-pro 007) if you don't require as much of an effect.
...
I've used both 89B and 87 IR filters with Maco 820c but as others have mentioned I'm not sure an 87C will let much light through which is visible to the film. As a rough estimate in midday sun in...
I recently purchased a new Paterson tank and reels and found the reels quite difficult to use. The bearings are small and rough and have a habit of sticking in the reel so that the film won't...
Thought I'd update this thread for those interested. Firstly I managed to give the enlarger a good clean and it came up pretty well considering its age. These things really are built like tanks. ...
Seems like a lot of people are pushing the digital route so although I'm in the minority and going against the trend I'll mention that I prefer the wet darkroom for colour. I tried the digital...
For a rough estimate of pixels per inch you can multiply the lp/mm figure by 50.8. Something like Velvia for example is on average somewhere between 4000 and 8000 ppi depending upon contrast. Tri-X...
Hi Ian,
You could try a pre-flash before the main exposure along with a metol only developer such as D23 (avoid hydroquinone as it builds contrast). Two bath developing may also help although...
Ilford changed the labelling for their '+' films from black to white a while ago (before the administrators came in). If this is the label change you're referring to the emulsion is supposed to be...
Hi Wayne,
Velvia 50 is leaving to be replaced with Velvia 100 (not to be confused with Velvia 100F). Faster, finer grain but less sharp. Press release is on the Fuji site.
Hi Tom,
As Jim suggested Ralph has pretty much answered your questions so I'll only add a little. I'm also a wet darkroom person so can't comment on photoshop manipulations or drum scanability. ...
Hi Nick,
Yes, I'll wait and see how I go. As John later suggests I may be able to get away with using the 80mm for the minimal amount of 35mm stuff I actually do. With the LPL I needed the extra...
Hi Ron,
Try an unexposed but processed sheet of E6 film. It's close to an 89B/Hoya RM72 and blocks most visible yet passes through IR. This is the basis for the dust detection in high quality...
Hi Neal,
Thanks for the filter source. I'm hoping it'll clean up okay with something but it's good to know I can replace them if necessary. Do you know if the older Durst filters fade much over...
Thanks Nick. I'll download the manual over the next few days for reference - I'm on a dialup so it'll take a while. The 50mm lens I have is a Schneider Componon-S f2.8 which is fairly similar to...
After a wait of a couple of years I finally managed to find a colour 4x5 enlarger for the right price (free) and one which didn't cost me a fortune to ship (free again). It's an old Durst L1000 with...
My 4x5 transparencies are individually sleeved and in the box when I pick them up after processing but the sleeves are a snug fit over the film and fit easily in the box without buckling. You could...
I use a Nikon 90mm/f8 with 4x5 and haven't found any need for a centre filter on transparencies at the apertures I most commonly use (f19-f45). With focussing at f8, yes the corners are darker (part...
I'm here. There seems to be a bit of a gender bias in the responses though.
Hi Darin,
I have a Nikon 90mm f8 on a flat lensboard which fits on a Toyo 45AII. The bellows are pretty squashed and the rear of the lens is physically inside the opening of the rear standard...
Perhaps I shouldn't have used the word 'resolve' and instead kept it more subjective however my usual viewing distance for prints of this size is around 600-700mm. Yes, my eyes are quite good...
A year or so ago I had a crisp 4x5 transparency professionally scanned and a 10"x12.5" print done at the usual 300 dpi. I wasn't very impressed as it didn't even compare with my own optical prints...
I've been researching the same issue but for a different reason. The smell from rapid fixer is getting up my nose. :-) As others have mentioned the difference is in which thiosulphate is used. ...
Thanks for the responses. I checked out Freestyle and couldn't spot anything other than the Maco and Fotospeed lith developers when I did a search for 'lith'. They did however have a nice...
I'm interested in trying my hand at some Lith printing but am a little worried about using a developer with formaldehyde (or para-formaldehyde) in it as my temporary darkroom isn't as well ventilated...
I'm only an amateur so I don't need to worry about workflow and although I don't do a lot of architectural photography I personally prefer the look of film to digital. The texture of brickwork, ...
Just realised I made a grammatical typo with my reply - whoops. Anyway without knowing exactly what process you're using or what result you're trying to achieve perhaps the following will help. You...
Hi again,
One quick note about the Ilford Ortho Plus is that its claimed ISO rating is 80 in daylight (40 for tungsten). I've used it for unsharp masking (pictorial contrast) with excellent...
Hi,
Recently I was looking for the same film but was unable to find it (at least in Australia) so it wouldn't surprise me if Kodak no longer make it. I ended up purchasing some Maco genius Lith...
