Hi John,
Heard nothing back from the Choo-Choo People. So the little station might be a good second choice. I'll pay the therapist overtime John if you and I could talk him into a 2 for one deal. ;-O

Lee

Savannah, Cindy and I already have an on going 2PM Thursdays appointment. Bring check book.

John: I have marked off the time on my calendar and informed my beloved that I will be acquainting myself with your blond girls that weekend. Which, on top of telling right after returning from a trip out west, has further endeared me to her! Count me in this time around.

Dan,

I am really glad you are coming and the girls will be thrilled. On the other hand I’m not sure I want you alone with my good lookin blonds. Have you considered bringing your fair damsel as a make up gesture for your western indiscretions? Would this sort of event be of interest to her? She is most welcome if you and she want her to come. Only 43,095 people and whoever they show these posts to will read the answer.

Dave,

Glad you are coming. Hope you are enjoying the lens. We haven't had anywhere near the amount of rain recently. The falls were great and I don't think I ever had as much fun delivering a sale. Come on. I think you will enjoy the other folks attending.

The girls especially enjoy hikers so you and Dan Henderson should be well admired.

Whew. Five weeks of Alternate Processes, summer course, U Akron. The class met 9-1, Monday through Thursday. The reality most of us stayed to 4 or 5 every day. Some had to leave for a second class and returned to stay until the wee small hours. We could also come in Friday to work but no class. That sure beats a three day workshop, but I am pooped. It was such a success that there is talk of making it a ten week, six credit course next summer. I hope I am that strong at 71. I have some prints to show in September. The full time students have many prints to show. Final critique is tomorrow. I hope you all are working on some good stuff to bring in September.

Sounds great John! Looking forward to seeing those prints.

Thanks Jeff. It has been a lot of fun and learning.

Bill, Glad you will be coming if your employer doesn't have you scheduled for that weekend.

Hi John,
Tell me what types of processes you worked on. I love Van Dyke and is my first choice in doing that kind of work. Gum is my most troublesome type , although I have seen some nice gums before, usually smiling and with teeth. I'm certain if you did gum prints they will have a strong bite on us when we view them.

Hi All,
Wondered if any of our group has had experience with Ektar Film. I picked up some 120 rolls in hope to shoot some fall colors this Sept and Oct.

I wonder how it does in deep woods, no direct sunlight and long exposures of 2 to 12 seconds, +++. I put a test roll in the camera last night and will do a walk about over the week to come, hopefully finding some deep woods streams and lackluster waterfalls compared to CNP up there. I figure I will know when I am deep enough into the woods when the bugs are eating me alive, so I can test long exposures.

Lee,

I've tested Ektar for reciprocity failure using a standard astrophotography methodology. That consists of shooting one frame at 1/8 second (.125 seconds), then putting on a 10 stop ND filter and shooting at 125 seconds (.125*1000, which is 10 stops), bracketing exposure with aperture. You can calculate a Schwarzschild exponent from the number of stops adjustment necessary to get density equal to the shorter exposure.

The Schwarzschild exponent I got for Ektar 100 was about 0.81, not particularly good, not terrible. No reciprocity failure = 1.0. Films with low reciprocity failure are in the .88 to .98 range. For Ektar 100 with a Schwarzschild exponent of 0.81 in the range you mentioned, 2 seconds adjusts to about 3, and 12 seconds to about 23 seconds. I haven't checked color crossover or color shift.

You can make up your own reciprocity adjustment table with a spreadsheet and the following formula:

corrected exposure time in seconds = (metered time in seconds + 1)^(1/p)-1

with p being the Schwarzschild exponent.

Lee,
Great information. Thank you so much for this insight. Looks like you did a very comprehensive study of the film. I'll plug the formula into Excel and see if I can make something work. Might make a little cheat sheet and put it in the light meter cary case.

So, did you like the look of Extar? I've used Fuji 160S for quite a while and have heard they may stop making it. I do not know what to believe there. I would think the Fuji people will outlast Kodak in making film but that is only my guess.

I've shot several rolls (6-8?) of Ektar 100. The reciprocity test took about 5 frames on one roll, one for the short base exposure and the others for brackets at 125 seconds. I like it a lot. Internet reports of exaggerated Ektar 100 saturation, cyan skies, and blocked up reds don't hold true for me. I would have shot a lot more Ektar 100 if I weren't trying to finish off the Kodachrome and had a smaller stash of C-41 films on hand.

I've been through a couple of bricks of Pro 160S. It has been my main C-41 film for a while. I think the official Fuji line is that Pro 160C was/will be dropped and Pro 160S will continue with a name change since they won't need to distinguish between two Pro 160 films. I'm not placing bets on who will make film longer. I'd like to see them all continue to produce as many different films as possible.

Lee,

Sorry for the slow answer. Dolly and I went to see the Cartier-Bresson exhibit in Chicago and just got back Tuesday evening. Fantastic show. 460+ prints. As you may remember Dolly is a water colorist and was ecstatic viewing the twenty three Monets at the Art Institute.

In the Alt Processes course we were to work in Cyanotype and Van Dyke. I had one problem after another with my negatives and Cyanotype, so for all intents and purposes I worked in Van Dyke. Eight of the 7x17s are matted and in a show now, but should be back by our gathering. The 8x10s are also matted and at home.

This being my first experience with Van Dyke it was really interesting to compare the silver contact prints with the Van Dykes. I learned the tonal range is really much longer than silver and needed to be much more contrasty than what usually works for me in silver. The negatives that printed best were mostly ones that had too wide a range to easily print in silver without much dodging and burning. I noticed the other students were printing digitally enlarged negatives in 5-10 minute exposures in the UV light box. My Rollo Pyro stained negatives were 15-48 minutes. A step test and then a print meant I was lucky to get two good prints an eight hour day. Some time ago I bought a used Ameragraph 1200 watt mercury plate burner with vacuum table that I will start working with soon. That will reduce times to a more reasonable range and increase the electric bill to a less reasonable range.

I made it to the Akron show. Wow! is all I can say! The photography was stunning. and the multi-media show at the end was also breath taking! My artist friend hadn't seen the new building so being able to tell him "I told you so!" was the best! He was really impressed with the whole place, especially the photography, and wants to know why I can't print that big. He also wants me to do a solo show at the gallery in Erie so I really need some help with a portfolio and a lot of other things. Sorry I missed the last get together.

Cheers,
Dorothy

Great stuff on the flicker page. I really enjoy the expressive views of nature. You make Dolly & John's pond look like my dreams.

Dorothy,

You are so demanding. Did you stop by with your fellow? Did we go out for your favaorite Indian food and hear what is about? Did we get to see his work? Why, the girls didn't even get to sniff.

I'm with Lee. I love the new work on your flicker page.

Hello.

So I've heard (pushy) I call it enthusiasm ;) I'm sorry, no, we got lost in Kent, and of course, no maps or gps, then off to Akron, then straight home. The week before we went to Pittsburgh to the Carnegie Museum to see the AAP show which was great. There was an Indian restaraunt in Pittsburgh we went to which was really nice. He's pushing me to do a solo show, (and to draw! ha ha!) and I keep saying I'm not ready. I don't even have a portfolio which is where you guys come in. I need help! Maybe one of our experts can have a talk on how to put together a thesis and portfolio at one of our gatherings? I need to quit experimenting and start printing. Looking forward to September. Hope I can make it this time. Thanks Lee & John, for the compliment.
