There's a few images in flickr and in camera-wiki.org
Asahiflex I-2 | TOM | Flickr

If it is in the books by Keppler and by Gerjan vanOosten, my doubts are very very small

DDX came out in the late 90s/early 200s (ilford DataSheet from 1999 says "Coming soon")
At the time, I got a test bottle from David Carper (US Ilford R&D) and tested several combinations.
Datasheet from Ilford

For most ilford films (HP5, Delta400 I and II and Delta3200) it was great; very forgiving and nice balance otf tonality and grain
Even in D3200 at 6400

But where it shined above anything else was in developing 400 films (Foma, Fuji Neopan, TriX); allowing pushing by 1 even 2stops maintaining good shadow details and not exaggerating the grain
Yes 1+9 was possible, besides the 1+4 recommended by Ilford. I have to look for those notes for times but the MDC is usually spot on..
PS1: Found this in an old thread (by me)
I posted this before, increase DDX dilution from 1+4 to 1+9 and increase time by 125%. I also agitate less often (once every 2 minutes).
1+9 DDX canbe reused for 4 or 5 rolls, as long as you increase another 10% of the time for each extra roll. I make 1 l and develop 2 35mm at a time (600 ml) and then remix the used and "new".


I used to collect 3 or 4 rolls to use 1+4 solution a few times, starting with high speed film and finishing with slower speeds (Efke 100 or Agfa100)

I believe that there are a few threads in Photio and Photo.net about this started by me (Ilford used to have a great forum that I think is closed now)

Try Ilford DDX, it is probably one of the best fast film developers out there.

not bad, with a 200mm lens I could shoot the pleiades for 90s without trailing, at 120s you see some but they are very high in the sky ~70deg

How did you develop it, your tonality is incredible and there is almost no grain!!!

Looking at raw files, the "grain" is not a single color but a series of colored dots, I can see pink and cyan
While in a enlarger (Nikkor 50/2.8 enlarger lens) all I see is grain in 1 color

Thus, chromatic aberration also plays a role??? Ae the silver grains "bending" light and creating diffraction?

Original 'Spot-Matic'

There was a 10yrs difference between those cameras but a eon in technology advances between them
Electronics miniaturization happened in between, which allowed for smaller and more reliable electronics at a better price (aka cheaper)

The spot meter in SPotmatic (1960-62) was not economically feasible at the time; but in the CL it worked like a charm.
Among other factors the Leicas don;t have amirror, so the arm doesn't block the view and can be smaller and move shorter distances

New owner here, tested PS with macro and it makes a world of difference. Macros are sharp and detailed.
However RAW files are in the 100MB order!

Those are not sharpened, shoot with K5IIs (natural)> converted to grayscale> invert> levels adjusted> and cropped only

Grain looks unnatural in scanned pictures compared to prints (Fomapan 400)
My guess is that pixel shift will bypass that

I just upgraded from the K5-iis to the K3-iii and all the new features are mind boggling
Pixelshift is one of them, thanks for the info

With the K5-iis , a Pentax Bellows, and SMC-50mm Macro Takumar I'm able to do 11x14 prints which look good
However some BW negatives are tricky, and pixel shift might help dealing with grain.
i'll give it a shot

I wonder if pixel shift will help in "scanning"
I've been happy with an old bellows/slide copier from the SP days

Updated from the K5IIs - I think the VF is actually great, a lot easier to see the level and the setting in bright sunlight than the older ones
And the electronic frame-lines are great, much easier than buying focusing screens

It happens, and it's worth every penny
Eric services are fairly priced (inexpensive for the great job if you ask me), and the result is incredible

Other brands charge a lot more for service, I recently had a pre-war Zeiss lens serviced for a lot more than what Eric charges for a full camera service

Spotmatic F meter?
Posted By titrisol

OK gotcha... a question
Are you using the same lens (SMC) fully open and in stop down mode?
or 2 different ones?

The Spotamtic F uses a movable cam (marked 2) in the lens to get the information of aperture and a index positioning cam (maked 3) to ensure that the reading is correct

If either of those on the camera side is bent or not moving correctly you may get discrepancies

The lens-information cam in S-M-C lenses can fool the meter if you try to use it in stop-down

If you are trying a SMC and a SUperTak (identical) the 2 stop difference can be the same aperture cam that is bent on the camera side
