@lamarpi314 There is no such thing as an average time for development. The timing is determind by the type of film and developer. The timing is absolutely crucial, to fail to correctly time your development will seriously compromise your results.
Stop bath needs 30 seconds, fixer 3-5 minutes, but these are both dependant on the brand of chemistry used.
Why do you need to take the film leader out in the first step ? You are going to break open the cassette in the dark cubicle to get the film out anyway.
@psur47 Taking the film leader at the start means you do not need to break open the cassette, which makes loading the film in the dark a little easier.
@renegadepoptard The developing time depends on the film you are using and the developer (and also the temperature of the chemistry). Development times vary between about 4 and 8 minutes, in this instance I developed for 7 minutes.
Ilford ID11 and Kodak D76 both can be used over and over. We used a a five litre tank which processed about forty films and was then dumped. Using a rapid fixer means you can do away with a stop bath. You should also have all the chemistry ready before loading. Checking the temperature of the fix before putting it in the tank means it will still continue developing - even with a stop bath used.
you said that i have to dump the developer after use, but i read that we can use it for two roll and then raise the developping time. Of course the result will suffer. But a mix of 350ml can be use for two rolls right? That's what i want to do, is that OK?
@driveslowly It depends what type of developer you are using. The one I used in the video, Ilford Ilfosol, is single use only and I definately wouldn't use it more than once. T-max developer can be used again for up to 4 rolls of film without any problems. Remember the developing stage is the most important, so it's worth getting right and not making any compromises.
@pippinrogers I use Ilford too. I just finished developing, I follow what you said, i dump the chemical, I kept the stop bath and the fix. I think the stop bath is good until it change color to violet. And the fix, I hear I can go for 4 rolls and then change.
@driveslowly Yes the stop bath will go purple when it is exhausted (providing you have bought indicator stop bath!). Fix will last for a while providing it is well covered or in an airtight bottle. If you notice that your films are not clearing completely or have a slightly purplish tint, then the fix is probably exhausted.
@iallisonjuliette If you put it in a heated drying cabinet, it will take 30-60 mins to dry. If you just hang it up and let it dry naturally it will take about 6 hours.
You only need to load the film into the developing tank in complete darkness (the stage of the video which is black and white).
hello, thanks a lot for this video I have just had my first attempt at home developing tonight, first half of film seems to have come out really clear! Second half has no images... but that might have been camera trouble :s don't suppose you have any other suggestions as to what I did wrong?
Sounds like camera trouble! Can you see the frame numbers and film branding on the edge of the blank section? If so then it is definitely a camera problem rather than a developing problem. Only other thing it could be is if you didn't load the film on to the spiral correctly so some was overlapping, but I think you'd know if you'd done this.
Thank you, yes i can see the frane numbers... who knows whats happened then, very strange! It felt like the film went onto the spool smoothly. Oh well, thanks for your quick response!
Hi :) I wish to process black and white negatives and would like your recommendations as to what developer and fixer is best and affordable? Also, is it absolutely neccessary for a rinse-aid? when I was developing films at college we didn't use a rinse-aid.
A good quality easy to use liquid developer is Kodak T-Max. If you are doing a lot of films you could go for Ilford ID-11 or Kodak D76 which are in powder form and mix up to make 5 litres stock solution. Ilford Perceptol developer is good for very fine grain and sharpness, although is not so economical. For fixer I always use Ilford Hypam fix. It is not essential to use rinse aid, (but it does help prevent water drying marks), you can use washing-up liquid instead. Thanks.
Yes there is a difference between black and white and colour processing. The chemistry used is completely different, and there is a bleach/fix stage rather than just fix. Also the temperature is critical and must remain constant throughout development. So I would say the processing of colour films is much better left to a photo lab machine!
Some types of developer can be used more than once (e.g T-max developer), however the one I used in the video (Ilford Ilfosol) is single use. If you were to reuse it, it would probably work, but your film would be underdeveloped. Thanks.
Hi, yes a stop bath can be used after developing, but we have stopped using it to reduce the amount of chemistry we use, due to COSHH regulations. A stop bath will immediately stop the development process, without it the Fix will become exhasted more quickly. Thanks.
Can negatives that was exposed to light be developed?

So what is the average time for developer, stop bath and fixer? In just use the 7 5 7 rule, someone?

what would happen with a film if you would re-use old development fluid?
