Question HARMAN DIRECT POSITIVE PAPER FB Glossy - Safe Light ?

I have just bought some Harman Direct Positive Paper to test some second hand Film Holders acquired on E-Bay

Can you handle the paper under a dim Safe-light or does the emulsion require complete darkness ?

Anyone care to share their experiences

Thanks

Martin

From the Harman site:

2. SAFELIGHT RECOMMENDATIONS
Unexposed paper must only be used with Ortho (deep red) safelight such as ILFORD 906 containing a 15W bulb or equivalent. As a precaution against fogging, it is advised that the light be a minimum of 1.2m/4ft from the paper at all times. Safelight exposure should be kept to a minimum and unused paper returned to its original packaging for storage.

As Dave mentions, follow the recommendations and you'll be fine. I used a kodak GBX-2 but any Ilford or Kodak Dark/Deep Red should be fine with the right bulb, distance and exposure.

Thanks

My Duka 10 and or Duka 50 Safelights produce a spectrum in the 590nm range - which seems to be not far off the maximum sensitivity for the paper.

It looks like I'll be groping round in the dark, developing my test "prints" for light leakage.

Probably easier to use gloves than try and use tongs to handle the wet prints in total darkness.

Thanks

Martin

Martin, if this paper is likely to be a regular part of your portfolio of paper and if I have understood you correctly the Dukas are barely safe then it might be worthwhile getting a deep red.

On bulb cost replacement grounds alone the Dukas can be expensive to use. I confine mine to RA4 paper only for that reason.

I've used it under a normal red safelight and it seemed to work perfectly well. There was no evidence of fogging as the white areas were very white.

I can say the same as Niall.

I've used it about 3 feet away under a 'normal' paterson orange safelight and had not problems handling and developing it at all.
