Hi,

Does anyone have any information on processing 10x8 Black and white film at home using a Jobo CPA or Unicolor processor. I do not have the use of a darkroom at the moment but have the use of a changing tent to load the film.
Any ideas on tanks to use would be of great help. Thanks.

Roger

Hi Roger,
I use the 2840 tank with a 2523 extension. You could fit 2 negs at a time. Place the emulsion side up and process as normal. Hope that help.

Regards

Hi Chong

Thanks, I do have a 2840 and extention, I will give it a try out as soon as I can and will let you know how I get on.

You may want to read some of the threads on photo.net regarding mono sheet film processing and rotary processors with continuous agitation. My own experience has been with 5x4 film in the Jobo sheet film reels (4 sheets per reel, not 6). FP4 and ID11 and sticking to the published times - the increase in contrast due to the higher agitation was perfect for my enlarger at the time. I'm far too sloppy to do the Zone System so I don't do any fancy expansion or contraction in development. Does that mean I won't go to heaven?

Like you, I am lacking a darkroom at the moment. I'm even lacking a place to put the Jobo. For now I'm using Polaroid Type 55 pos/neg so I can get quick results and get to grips with the disipline of LF shooting again. Much too expensive for the long term, though.

Hi,
I do use type 55 for 5x4 mono work as well as unicolor and Jobo processor, all of which produce good results. This will be my first try at deving 10x8 film outside of a full size darkroom. I will have a look photo.net. thanks.

Roger.

Hi all,
A quick update I just processed some 10x8 HP5 plus in a Jobo 2840 Drum using Kodak Tmax developer for 6 1/2 mins. The results were perfect without any staining or uneven development. Thanks to everyone a problem solved.
Now all I need is a scanner large enough to scan the in one piece, at the moment I use a Canon 9900f but the tranny unit is to small, suggestions would be of great interest.

There really is only one option, the Epson V700 has an 8x10 film holder.

Unless you can find someone who still has a 4990 in stock, which you might be able to get cheap. There could still be some retailers with some left I'd have thought, and as it's been superceded, could be discounted.

If you're scanning 8x10, you'll be scanning directly on the glass, which means the extra lens in the V700 and V750 won't be used anyway.

DJ, you're absolutely right. This could be an advantageous route; the 4990 should be every bit as capable, as long as the plane of focus is on the glass and not above it (which I thought it was ?)

I think it's supposed to be just above the glass, virtually on it, but experience from owners reports on the internet suggest they vary wildly from unit to unit. Some people have had theirs up to 3.5mm above the glass, one unlucky soul had his under the glass! mine was I believe 0.5-1mm above which I think is about right, and they're supposed to be.

Hi DJ, you may want to look at the Scanmax wetmount kits, they are cut to size so will work with your Canon.
I have one for my 9950f 5x4 and I really like it, cost is quite good too. I can post an email address if you were interested.

Hi,
Thanks for the suggestions I will look out for a Epson 4990 or v700 and a scan max wet kit as my canon 9900f does not cover the 10x8 format the address would be handy. any other ideas would be great.
