You might find this article interesting if you're considering LED panels. http://www.bjp-online.com/british-journal-of-photography/report/1934699/hybrid-copy Colin White - Photography and Digital Imaging Tel : 07530 330 293 http://www.niepce.co.uk Date: Fri, 26 Apr 2013 13:44:33 +0100 From: [log in to unmask] Subject: Re: Light source for copy stand duplication To: [log in to unmask] Thanks all so far, our new softboxes are still a little large to get under the table we have, I would need to see if I could get it all under there I suppose. Point taken on the double diffusion, I had wondered if using a head upside down would maybe not give enough diffusion. A colleague had suggested LED panels, as a framer we use is offering these for the transparency type lightbox photographs we have in the collection. No idea about them and the LED spectral curve could be dubious for colour in particular, but interesting nonetheless as they are very thin with not much heat. Might work for B/W negs?

I looked at an old 5x4 and a 10x8 enlarger head with a cold cathode bulb and it looks good, but I just wondered if anyone has any experience of this and could recommend something maybe more suitable in terms of uniformity of light, light type, spectral response etc. Regards Tony Harris New Media Officer & Photographer Government Art Collection 0044 (0)20 7580 9123 www.gac.culture.gov.uk www.facebook.com/governmentartcollectionwww.youtube.com/user/GACpodcastsRevealed: Government Art Collection brings together nearly 200 works spanning the breadth of the Collection from 16th century to the present at Birmingham Museum & Art Gallery until 24 February 2013 and then touring to Ulster Museum, Belfast from 15 March to 9 June 2013.
