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

@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.

First of all thx for the video,

What brand or kind of Reel is that ??

[pippinrogers]

@eakiboz This is a Paterson developing tank and reel.

Can negatives that was exposed to light be developed?

[lzRosamund322]

pretty good

@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.

This was very useful for my photo and graphics course. Thank you for posting.

[renegadepoptard]

how long is the developing time?
