    How to clean standard bellows?

    in Large Format

    Posted

    You can by some small brushes and other vacumn cleaner attatchments that are for shop Vacs. They will also fit with the right adapter on a home style canister vacumn; sorry the name of them slips my mind at the moment it may not be a canister style, but not the upright ones, the kind with the hose, and attatchments. I picked mine up at Sears. The vacumn I have you can adjust the suction on the end anyhow. They also sell some very small shop vacs That would be ideal for things like bellows, camera bags, Changing tents, film holders, ect.

    Use of a step wedge.

    A Densitometer may be handy, and and understanding of the Zone system or some form of sensitometry. Suggest a visit to your local library to start. The Negative, by Ansel Adams; Beyound The Zone System; The Simplified Zone System, The Ansel Adams Guide to Photograhic Techniqes, by John ???. Stoufer also makes comparison strips if you don't have use of a densitometer. Here is there link http://www.stouffer.net/

     

    Just don't get too caught up in all the testing. Excuse my spelling please.

    Messed up testing Acros 100

    in Large Format

    Posted

    Don't laugh! I spent the better part of a couple days plus testing

    some Fuji acros 100 in a Jobo tank with 300 ml D76 1:1 68 Deg. I

    Started at 8:30 min rated at 100. If i liked this film I am convinced

    to spend the extra money to eliminate dust, and loading holders in my

    camper. Anyhow I bought a stoufers 21 step wedge. Well 1st it took me

    a while to find a holder that would accept the film and step wedge.

    Then put the gaffer tape to it, because it was in rough shape, but

    the only one that accepted film and wedge. I also loaded 2 more

    holders, thats 4 more sheets to test by the method described in

    the "NEGATIVE". So thats 6 sheets 1 for film base+fog. Well to make

    this story shorter my wife had moved the center core of my 2500

    series tank into the laundry room were I was storing some house paint

    rollers. Well it took me two loads of acros and a load of delta 100.

    to figure out that I had a light leak, and part of my tank was

    missing. I have always adjusted about 15% for rotary processing, then

    Fuji told me that they recommended a 1 min. pre wash and regular

    times as a starting point for acros. At the same time I decided to

    down rate my last test to 50 ISO instead of 100. Well it came out

    that if I would have left it at 100 ISO at about 10:00 min. with a

    1min pre wash I would have been right on. NOW Can some one help me

    with what little film I have left to do another test if these times

    and speeds sound correct for acros 100 and D-76 in a rotary

    processor? Does Acros usualy come out around 100 speed? Does 10:00-

    10:30 min. sound about right for D76 1:1 @ 68 deg. with a 1 min. pre

    wash? Help me please! It has been a long winter and I am loosing it.

     

    Oh ya I forgot about the one holder were I forgot to compensate for

    my luna-pro f attatchment, that was 3 stops off. I guess it is worth

    a good laugh now that I can look back on it.

    do you use analog exposure scale?

    in Large Format

    Posted

    This is why I like the Luna-Pro F analog meter. Yes it only goes down to 7 1/2 deg. with attachment. I like the null needle with +/-3 stops also. The only problem is the darn thing calculates in every concievable way; also alowing you to mess up in every concievable way.

    Developers and true film speed

    in Black & White Practice

    Posted

    Stephen, I just read an article a couple of weeks ago while browsing at Borders, Perhaps you wrote it? It was very well written, I can not remember the name of the magazine; maybe it was View camera techniques, but it was saying the same thing about the zone system error and flare. From what i understood in a quick read was that the zone system was inherently developed off by 2/3 of a stop. It made sense that most people would come out with just about that or a stop lower in there personal film speed. I didn't understand why flare would have anything to do with this, but i just accepted the fact that personal film speeds where off by 2/3 of a stop, so why not take everbody's advice and half the stated ISO rating; being 1/3 of a stop conservative. Am I making sense? I am almost positive you wrote this but my memory is failing?

    Regards,

    Air cable release

    in Large Format

    Posted

    A little off topic but, Can anyone tell me if the shorter ones are better than a regular cable? Do many of you use them? I can not imagine an air release being any better than a cable if you have a solid setup? Are there any advantages? Any comments would be appreciated.

     

    Thanks,

    150mm lenses

    in Large Format

    Posted

    Take Chris's advice and stick with one lense to start with. You will get many oppinions on which one is best. I started with a 162 optar, and then went to a 210. I prefer the longer lens. I recently had the money to upgrade my older lenses and found a nice 180mm Nikon I couldn't pass up on a secound chance bid offer, at the same time I also found a nice 150mm at a price I could not pass up, both are in prestine condition and I can't part with either. Anyhow I would keep your eye out for one lens to start and get use to that. I have never found myself changing lenses often, I think alot of people have their favorite and pretty much stick with that one even though they have 5 or 6 lenses.

    Good luck,

    Dan

    "I saw 6 mergansers. That was the first time I had ever seen any in the wild. For those who don't know, a merganser is a duck that always has a very bad hair day."

     

    Around here there are too many, For those of you that hunt for food, and sport they are the worst tasting duck there is. Pointed bill=fish eating duck= fishey taste. Yes they do have a bad hair day. Now a wood duck with a 4x5 would be a treat.

    Congratulations!!!!

    Wow! I can not believe some of you are having such a hard time with these reels. Sit down in your easychair while watching TV and practice in the light. Then close your eyes and practice. I load mine in a bedroom closet with a blanket over the door just for insurance. I still catch myself loading it in the dark with my eyes closed,,,LOL. It is realy not that hard. I will try to take some pics also. To be honest with you when I saw those black clips I was very nervous about putting them on in the dark. I now find the black clips the easiest part. They snap right in nice and easy once you get a technique down. I find holding the reel horizontaly with both hands with the index fingers in the spool and snap down each side with your thumbs. A pic. is worth a thousand words. It is not so difficult to give up if you practice 15 min in the light you will have it down.

    Jim, have you ever used the spotone or such on the negative,or just the print? I never had the old nose grease trick work for me.

    Also have you ever used the spotpens? Just curious, I used them a few years ago in a class, and I found them much easier than the spotone and a brush. Although it seemed every time I spotted something it looked worst than before i worked on it. I use RC paper and my teacher did a pretty descent job. However I found it hard to master. We were taught to SOMETIMES take an exacto knife and carefully remove the top of the spot so the tone could penatrate. It seems like this is an art in itself but is part of the process of large format sometimes?

    I know a little off the topic sorry!

    JOBO 2521 tank and 4X5 reel loading

    in Large Format

    Posted

    Your 1st change may be to get rid of the loader system. When I bought the reel and tank a couple years ago the jobo tech. didn't recomend the loader either. I think that is why you see them on ebay often. As the others have said practice in the light. I found it took no time to load them in the dark. IMOHI it's easier than 35mm reels.
