I'm working on a compact hack to make an electronic finder and focus assist for my 8x10.
We are trying to use a compact sony as an electronic viewfinder for my 8x10 and hacking the software to extract focus distance values.
The compact will sit ontop of the 8x10 lens. The monitor will be a Samsung Note and the app will give the assistant/photographer
bellows extension values. This is for a portrait project of mine using paper negatives. The face recognition in the compact will make things work nicely.
I'm also designing the app to adjust paralax based on the focus so as to give accurate framing.
I may be handing this off to Fuji as they have shown some interest in it.
This may be something that might work with a tech camera.... waddaya think....

What you need is an 8x10 Gowlandflex:

I wonder if you could not make something buy stacking two wooden 8x10 view cameras. Most compacts do not have distance encoders.
-
omg I want one of those.

The Gowandflex won't take an 600mmm and focus close enough. Not even close enough for the 480mm..... unfortunately :'( :'(

While awesome in many respects, you need a latter to use the damn thing, and on he street it was all too cumbersome, except when I had it in full production with several assistants and the street blocked off. It was cool, and in a studio he GFlex was fantastic. For 810 I like an F2 with the auto shutter. Fred's compact sounds awesome. I've used video cameras on the GG before to varying degrees of success. For 4x5 the Technika IV - MT's rangefinder works surprisingly well, but longer lens choices are limited due to he puny front standard and lack of bellows extension.
Fred, I dig it.

Fred, I've been hashing around something similar but less sophisticated than your idea, for my Cambo Tech camera.
I think something like this is badly needed and I'm surprised some genius hasn't come up with something yet. I keep getting hung up on the fact that Phase One backs use Firewire and nothing but nothing is going to connect to it - except an Apple computer - not even my effing iPad for God's sake!
I'm interested in your choice of the Samsung for a monitor - which size and how come? Thanks.

It's a 5.5 HD Super AMOLED screen. Great color and black and white performance. 1280 x 720 res. Very power efficient.
It's expensive, but sort of free if it's also your phone.
Other reasons for choosing it is the quad core processor and it has IT management layers that can be used for remote tech support.
Really helps in the development phase if you decide to get fancy....
However being that this is really just a framing tool... sort of a rangefinder for my 8x10 screen quality isn't too important, but I'll be using it
for other things too.

@Fred
This is silly. 10X8 is a complete waste of time you can get much better results with a D800.
These large format camera companies are basically trying into con people into believing that their cameras are better, some of them are not even made in Germany!

Yes it's a conspiracy by the 8x10 makers. Fred, Don't let those younger photographers be fooled by this! :D

Wow 4 in a row!

$4000 D800+Lens VS $24,000 Hasselblad

My second 8x10 camera cost me a grand total of $ 1,775
Toyo 8x10 $ 380
Schneider 480mm F 8.4 Symmar $ 1100
10 Dark slides $ 275
(Paper negatives cost me about $ 0.75 a shot including chems.)
And these are a few examples of what I have done with that lens and the 200x250mm "capture area" all straight out of camera.
These are Polaroids:

These are new paper negatives.... I'm still figuring a lot of things out.... ???
Crop to about 4x5 paper size no preflashing the paper:

8x10 no crop no pre flashing the paper, but processed with a water bath technique.

Fred, those are awesome!!!!
-
Fred,
Nice to see a few different images from you.
Question: are you pre flashing your paper or using it straight?
-
Jokes aside, very good work.
Congrats!

Edited the post... some are Polaroid....
Only these are paper negative:

I thought I'd try water bath technique first to control contrast.
It works quite well as you can see from the second shot.
However it takes a bit to long to be practical for many shots.
What I do is repeated water baths so that the shadows develop faster than the highlights.
I develop for about 20 seconds and then do a no agitation water bath.
During the water bath only the developer infused in the paper is present.
The high light areas eat the available developer very quickly and stop developing
while the shadow areas are not as greedy and they continue developing.
After the water bath I put the paper into a diluted second developer bath
so as to sloooowly bring the midtones up. It's fun to see this all fade up on the paper.
I only wish I had negative vision ;)
Oh ... and these two were scanned at home with an all in one cheap ass scanner/printer....
I'll have to scan them again at the studio
-
Next experiment will be pre flashing paper.
-
Preflash to lower contrast right? (It's been 25 years since I did this)
I remember doing this for my boss we printed dodging with a piece of card every few seconds and when devved used the time next to the last 9(just) visible strip for the preflash duration.

Yeah, the pre flash is to reduce the contrast some. I'm just using it straight but I like the contrast.

Fred: awesome. Truly fantastic. What speed is he paper? 6 or something?
-
Simply amazing and beautiful Fred!

Fred,
Love your 8x10 images. Many years ago I used to shoot with a Toyo 810M and 360mm Goertz Dagor and drum process the negatives in Pyro to help preserve highlights. A couple of samples are attached.
I would like to find out more about the paper negatives that you are using. Any links or resources would be appreciated.
Thank you,
Richard

ISO for paper goes from about 6 to 20 depending on the paper and batch. Being that it is for printing ISO
can fluctuate a bit. Best to test each batch.
-
I use ISO 3 for the paper, but it probably depends on what you buy.
-
Fred and Eric, thanks! I'm going to try the paper negs and some Ilford paper positives.
Fred, you have a Toyo G? How is it weight wise versus, say a Sinar P with an 810 back? The Sinar is a bear to move around.
-
Fred- have you considered one of the new GoPro units? They have Wifi to broadcast Live View to a phone or a tablet. Lens is full of distortion, but replacments can be had I hear.
-
omg I want one of those.
Not sure if you were serious but happened to see this posting - this guy has two of them for sale!
