Paper flashing, Pre-flash examples.

I had not envisaged writing a second post on this subject so soon, but I thought I should have included some more examples with the first post.

Examples:

All the pictures that appear here have been printed on Kentmere VC RC at grade 0, developed in Ilford Multigrade and pre-flashed at one second increments with the enlarger light box at nearly full height and the lens shut down to F16.


Straight Grade Zero print


This picture is a straight grade zero print. When I took this picture I knew it would be a difficult scene to print.


Pre-flashed for one second

This picture has had a one second pre-flash the difference is quite subtle but you can just make out an increase in tone.


Two second flash

This picture has had a two second pre-flash and looks a bit washed out. The tonal range has increased in comparison to the last picture now making it necessary to add the grade five exposure to bring out the contrast and blacks.

Pre-flash test strip:


Exposure curve and Kentmere test strip
in second intervals


I have combined the pre-flash test strip for the Kentmere paper with the exposure curve to show how the test relates to the curve. Intervals 1 to 4 relate to the numbers on the curve.

Example two:

Grade zero print

This is also a grade zero print, when I took these shots I did not think the negatives would require pre-flashing.


Flashed for one second

This picture has had a one second pre-flash. If you compare the two carefully you can make out the subtle change in the sky which appears darker and the  additional tonal range in the details in the shadows.

Local Darkroom.

120 format FP4+ developed in ID11
Printed on Kentmere VC
Develop in Ilford multigrade developer



I received an email from Harman technologies (Ilford products) recently about a new initiative that is to be launched worldwide.



The email was sent because I took part in a survey about darkroom use. It had a large response with fifteen thousand people taking part with over a thousand replies on the first day.


This is a summary of the statistics:
  • 69% shot film weekly
  • 35% did not use a darkroom but were using black and white film.
  • 35% without a darkroom were asked would they like access to a local darkroom 78% of them said yes and of those 32% would like some training.
  • 65% said they had access to darkroom facilities provided by work and community with privately owned being the majority.

A second survey for privately owned darkrooms was done with thirteen hundred responses being received. They were asked if they would be willing to share their darkroom and 56% said yes.

With that encouraging result Harman have set up a new free online community www.localdarkroom.com They have already invited tutors and community/ public darkrooms to list themselves on the site. There is also a section for those that have a private darkroom who are willing to share their private space. You will need to be a member of the community to access any of these services, whether training or darkroom in the local area, as there has to be some sort of vetting when allowing people you do not know into your home. For FAQs and more information visit the web site.

I hope this venture is a success and praise Harman for their initiative. But from experience I note that there can be a big difference between what people say on a form and then taking part.


On a personal note I would have liked to open my darkroom to other enthusiasts but it is not practical at the present time.
