Darkroom.........................

There is another aspect to look at.

Now I admit I am by far not a chemist or some kind of screen guru.

Anyways lets say you have a screen momentary exposed to your shop lights, lets say .01% thickness has been exposed and cross linked. OK now you have a minute layer of pre exposed emulsion, now lets say down the road you re-pulll that screen out for some reason for the same amount of time, does the screen re-expose another .01%, no absolutely not because the light first has to penetrate the fist .01% before it starts exposing the next layer. We all know post exposing is much much longer than exposing, it takes light a long time to penetrate already exposed emulsion. That is why we post expose using sun light it is the fastest way and practical, it is not practical to post expose using your light source because of time energy and bulb life.

Anyways what I am saying is hitting a screen with shop lights here and there does not really accumulate not in any reasonable amount of time anyways.

But what do I know.

This morning I removed a screen from the darkroom and exposed it to ambient light for 1 minuet while registering it on my bible board before putting it in the exposure unit. I also let it sit in the exposure unit for ten minuets post exposure while I was talking on the phone with a customer. But thanks to powers that I do not fully understand the image washed out easily using only the garden hose nozzle.

Please accept my apologies in advance to anyone who I might have offended with this post, and understand my sarcasm.

Do you dip -and- hose -or- just give'r the hose ???

Some folks like the idea of a warm bath with agitation -then- give'r the hose until you get'r all cleared out ... imaging can be a lot of fun in a darkroom -or- a well light area <--- it is ALL personal preference (I guess)

Note: the above post may not be suitable for your workplace -and- protection should be warn during ALL steps of the process ;-) LOL

BTW ... Did your Pizzatol delivery man ever stop by ???

One thing I will say about this.

My experience with Robert this past week.

Robert is a very technical person.

He reads and researches a lot and is a perfectionist when it comes down to technical ways of doing things.

He goes by the book.

But some rules can be broken with good results.

So....you both can be right.

-----------------------------------

Ok...there is

fast and faster

maybe you guys can be

right and righter.....LOL

Nothing wrong with being technical until you understand what is actually possible/practical which you will ONLY get from doing.

I know a lot of "book smart" people that push carts at walmart or run a teller window at a bank for 30k a year. Nothing wrong with that if that's what they want to do, but guys like many of us are far beyond that **** because we put the BOOK DOWN and DID WORK SON. LOL.

There is "Technical"

And there is "Practical"

Enough said.
