Hello everyone! so a few weeks back I decided to grab a film camera, and I bought some TMAX 400 black and white film. last night, for the first time since high school, I developed my first roll. It came out great and all the images were clear and seemed well developed. I am using the powder developer from Kodak and fixer from Kodak as well (they were like $11 on amazon.com). so my question is: while watching this video that I followed, it was saying that if youre using tmax film, you can't re-use the fixer after one use. is this true?? and also, can I continue to use the developer and fixer after the first use? I saved it in an air-tight bottle. also, does anyone know the appropriate times to let the chemicals work? I read about 6 min and some say atleast 10, and others say less than 5 but with less agitations. please can someone help clarify this. the bag the powder came in has some instructions but I don't understand what theyre explaining. I have another roll I want to develop but im waiting to see if I can get some info. also, I have looked online, and either I am clueless to what I am reading, or I cant find much in writing on it. I am using 35mm film. Thanks for any info!!
