Sorry if this is not the right place for this post but I did not see any sigma

or lens forums. Its a general lens questions so I hope you guys could help

me. I have an old sigma sa-7n film camera. When I compared the built in light

meter to other cameras and handheld light meters, the sigma seems to need a

lot more light. Both of my sigma lenses are that way. I do not understand

this. I know that some lenses are faster than others because they can open up

wider with bigger apertures but does my sigma just have dim lenses that need

extra light at all apertures? Also, when I look through the lens before a

picture, sometimes it looks like there is a tint to my camera. Is this problem

common with some of the old sigma film cameras?

Thank you. I will keep that in mind when I start looking at other developers. Does diluting D-76 to 1:1 have any bad effects at all on film? Other than developing time, is there anything different about doing it that way? I am worried that it will change the quality of my film.

Thank you everyone for your help. I was kind of wondering when I would receive some straight answers to my question :-) J.V. it?s funny that you mentioned walmart because I was just looking at their thermometers the other day wondering if any of them would work. I?ve also seen some nice laboratory thermometers online for $20-$30. They look much better than the ones I saw at my local camera shop. I noticed that a lot of camera shops don?t just charge premium price for their darkroom equipment. They double or triple prices. Now I see why a lot of you recommend buying kits online.

These are both great links. Thank you for the help.

LOL! Thank you Jeff for your input. Maybe I rambled a little. I was just looking for some general information about thermometers.

Would anyone care to share their experience with this combination? Mainly

developing times for 100 and 400. Kodak only covers developing times for

their own film and I do not have a clue where to start. Any recommendations

would greatly be appreciated.

I just started using a 9 dollar delta thermometer for processing black and

white. I was looking into getting a faster digital thermometer. I understand

fully about the accuracy of thermometers (vary from one to the next) and how I

would probably be ok just using the delta for black and white. I would like

to know a little about the different types of thermometers. I really don?t

know much about thermometers in general. Can I use a meat/kitchen thermometer

to measure my developer? Does my delta measure the climate temperature as

well? Things like that. I don?t know much about thermometers and currently

am wondering if they are all the same and used for air/liquid/meat/anything as

long as they have the correct range. I know this might sound bad to some of

you, but I truly never learned anything about thermometers. Also, does anyone

have a recommendation for a nice and fast thermometer for a cheap price? My

delta is a little slow for me.

Just wanted to say thank you to everyone for their advice and suggestions. Distilled water looks like a subject that has been debated a lot. It would make sense to use distilled water to be on the safe side but it would be a big inconvenience for me. It might not be nessesary for my purpose. I think I will just use photo-flo for now. Thanks again to everyone.

Well if your using plain old tap water without a filter then that is what I will do also :-) I think the tap water in my part of San Diego is good. Thank you for the quick response. By the way, I took a look at some of your work---Amazing!

I will be developing my first roll of 35mm black and white and I had a

question about mixing the chemicals. Is it ok to use tap water or am I

suppose to use something to soften the water before mixing? Should I just use

purified or distilled water? The packages say nothing about the type of water

to mix with. What have you guys done?

Thank you for your help. I tried it both ways with a few scans and they seem to look the same. I will experiment some more and let you know. Thanks for the input people.

I know this question might sound dumb to some of you but I cant find any real

info about it on the net. I am using an Epson 2450 to scan my slides and I

was wondering which way to scan them. It would make sense to have them facing

up so that my transparency light unit could scan them from the top, but when I

do that they show on the computer backwards. I can also flip them with the

twain software but is that even a correct way to do it? Should I just scan

them from the back?
