I'm going to try to make it. I just spent $350 on Efke IR Aura 120 after learning of the demise of Efke tonight. Really down. Hope you can cheer me up. I can bring my new 8x10! :)

Happy to hear you will try to come. Bring the 8x10. Leave the downs.

I just shot my first 6 sheets of the 8x10 Ilford FP4. Now I just have to figure out how to develop & print... by the end of Sept!

Looking forward to seeing them. You will make beautiful pictures with that camera.

When you say figure out how to develop & print, is there a reason to do it differently than you develop and print other formats? You will do it beautifully. If not you will do it again, then beautifully.

Dick Phillips, the builder of my cameras, told me that as the cameras got bigger you needed to add a bit of exposure beyond what the meter says to make up for all that light that got sucked up in the bellows. It has proved to be good advice.

See you in a few weeks.

Thanks I made a spreadsheet to calculate reciprocity and bellows ext factor. It came out to 20 secs instead of 1. 15" bellows draw and 1 second exp. 8 1/2" lens. Sound even remotely correct?

Sounds about right, you've got nearly two stops of light loss due to bellows factor, bringing the exposure to 4 sec. then add in reciprocity. I'd say you've got all the information on the negative that you need.

I know film is expensive, but an experiment you might want to try while you are starting out is to bracket two stops longer, then compare the negatives. I have been starting out for about eight years now and I really like the choices that produces.

This one gets good reviews. Haven't tried it myself. Bellows factor is just one small part of it.

https://play.google.com/store/apps/details?id=be.hcpl.android.phototools&hl=en

ad supported free version and $2 for the ad free version.

Will likely check it out myself.

There are a number of spreadsheets around, and LibreOffice is in the works.

Also check out The Photographers Ephemeris.

Looking forward to the upcoming gathering next week!

This is a long shot, but does anyone have a Mamiya RZ or RB bellows hood I could take a look at? I'm looking for something for my 4x5, and I've standardized on 77mm filters, so this might just work.

I am excited about the gathering too.

Have some items up for sale on APUG. Anyone interested?

Hasselblad ELM, 9 volt, with prism finder, meter eratic. No back. on sale for $ 200
Hasselblad 150mm CF f4 lens with "Chicom" 3rd party hood. On sale for $425
Hasselblad 40mm f4 T * with extras, shade, caps, case, custom lens cover. On sale for $ 600.
All the above Hasselblad items for $ 950.00 cash, but you have to buy all 3.

I also have a Nikon N80 body, with AA battery pack and a 50mm f1.8 D lens, not listed yet. Great camera. Willing to trade this or anything above if it is cool and I would use it. (That is the hard part, if I would use it.)

Let me know if anyone is interested. You can see them under my profile here on APUG.

Dolly and John, forgive me for the sales plug, just trying to raise some $ for Sue's birthday and Christmas presents.
I am real excited to get up to see you two and the others.

Jeff,

I have an RZ setup, but I am not sure what a bellows hood is. That probably means I don't have one, but I thought I would ask if it goes by a different name. What does it do?

Looking forward to visitors from north, south, west and maybe east. You all come.

Lee,

I have encouraged people in the past to let us know what you have to sell, or as Jeff did, what you are seeking. We each help each other.

Thanks John.

It's a lens shade, collapsible, looks like a set of bellows. It screws onto the end of the lens on the 77mm filter thread.

Sorry. As predicted, if I don't know what it is, I probably don't have it.

I'm looking a nice 16x20 4 bladed easel :) I have a Saunders 11x14 I like. I'm not familar with any other brands but would like something of that caliber.

Looking forward to seeing everybody! John and I have been hauling the "big guns" down (8x10 for me; 7x17 for John) to the Flats in Cleveland nearly every weekend. I will bring some prints to show anyone who is interested. Like the Fry Farm, the Flats has an enormous diversity of subject matter in a relatively small area, although I don't think I have taken a single picture that doesn't have some steel (in some form) in it. See everyone next weekend.

Hi Chris,

Looking forward to your visit. Just a personal preference, but I would encourage you to look for a 20x24 Saunders easel instead of a 16x20. I think you will find that size more available than the 16x20. The school where I am taking photo courses has both 11x14 and 20x24 Saunders. As soon as you think 16x20 is great and doable, you want to make the next size larger, 20x24. I often see 20x24 for sale, but rarely 16x20.

Look for one with the all yellow background. Mine is all black, a little ancient and a little loose. I have always heard that Saunders was the best.
