Re: Achtung Phomi Meisters!

Karl, That's great, glad to be of help! Must admit I would be nervous of the impact of all those glass surfaces in the light path after 30+ years, maybe you could swap in a Universal head? The rest of the Phomi would be a great a source of prisms and mirrors for other projects (I already have the mi...

Re: Achtung Phomi Meisters!

Hi Karl, Shame I didn't see this earlier. Hope a reply is still useful... I had the same problem with my Universal - the slider was very stiff between the first two positions, and didn't improve with use. After some fiddling I found my way in - the good news is you don't need to touch the screwdrive...

Re: flat object reproduction photography - pixel shift

Ah yes, that makes sense. Ventilation - to keep dust down or get rid of fumes? I haven't got a special place no, I just set the mounting station on my lightbox. I try to get the area dusted first and then only take the film out of the sleeve to put straight on the drum. To dry I blow the worst off w...

Re: flat object reproduction photography - pixel shift

I wet scan most of my large format film. It is somewhat of a hassle, although I have the correct mounting station for my drum scanner. However the time taken in preparation is compensated for by the significant reduction in dust spotting in post. The fluid must carry the dust to the edge of the film...

Re: Windows XP HELP!

I ran my Nikon 8000ED like this on Windows 7 for a year or two, but I did encounter some problems - the ICE didn't work as normal. I have both the edited driver and probably some instructions saved somewhere if required. When I got my drum scanners a few years back I encountered a few problems. Idea...

Re: Two afocal photomicrography setups (now three)

Photo of this setup below. I've been using it quite a bit, more on the Universal where it seems a bit less top heavy. Ideally it would be worth replacing the metering inserts with some sort of plug.

Re: Two afocal photomicrography setups (now three)

There are more permanent solutions for shutters too. You're never going to need it even if it's nifty. Agreed. I had a go at using a low voltage to hold the shutter open but was unable to get so much as a twitch. So I opened it up. Unlike the clockwork nightmare of a traditional Copal shutter, ther...

Re: Two afocal photomicrography setups (now three)

PS, found this, so the shutter might be worth experimenting with a simple 3v to hold open: I have found for the Ilex shutters, for slower speeds, the 10x pulse requirement can be ignored, it's meant to get the shutter to snap open quickly by overcoming the magnetice hysterisis of the coil. For b and...

Re: Two afocal photomicrography setups (now three)

Which is the original position of the 63mm lens? My best efforts in measuring come up with the following: The 63mm lens is in a holder 6mm thick. The actual lens is thicker and protrudes slightly. The camera allows this to be positioned a minimum of about 20mm above the eyepiece (20.2mm to the moun...

Re: Two afocal photomicrography setups (now three)

Another Zeiss afocal setup using parts from the MC63a camera: IMG_4478.jpg There are usually MC63a cameras on ebay and usually cheaper than the 2.5x adapter Pau is using. AL-0451s.jpeg It splits into these components: AL-0452s.jpeg The bottom conical part gives a solid factory machined and adjustabl...

Re: A book review of interest to amateur microscopists...

These are available now in the UK for £18.77 including shipping - search on Abebooks. Highly recommended - really impressive quality, especially considering they were shot on 35mm film. Off to sample my local sphagnum ponds now...

That's exactly how it looks to me - very effective. Was going to remark on it even before I saw your comment.

Ah, great stuff. This reminds me of a good article which did the rounds a few years back. It's aimed at high-end video users but the issue is the same - essentially to make digital colour appear natural we need to decouple saturation from luminosity. The conclusions are more concerned with highlight...
