Solution wanted for Digitising Transparancies

Wanted -

Anyone have a good condition slide viewer light box for sale please. Looking for an A3 size light box maybe. I'm about to begin digitising my 35mm slides.

Thanks
Jeff

I had a quick look on ebay - and discovered they now make LED light boxes which seem petty cool! - link here:

Thank you very much Joshwa. Will look through the website.

I made my own - using a drawer, I bought a string of LED lights from Amazon and I had, fortunately, a spare piece of glass which fitted over the top. Sprayed this with 'frosting' and it works fine for transparencies.

And the CRI of this string of LED lights?

Don't know - but it works for transparencies - it's pretty bright!

It is 14m long, lights encased in a plastic tube, and spaced about 8cms apart and described as Ice White. No CRI given. I am not a professional photographer - just a hobbyist - and this suited my purposes beautifully.

I'm a photographer but not a very good DIY person - what is CRI ? and what is 14m long ? It sounds like a very good set up no doubt. The LED tubes that you bought off Amazon, what length were they please ? And I guess you screwed them into the inner side of the drawer ?

CRI stands for Colour Rendering Index and is a measure of how accurately colours will reproduce when using that illuminant, a high CRI means colours can reproduce more accurately, LED strings from Amazon will likely have a low CRI with parts of the spectrum missing with possibly poor reproduction of colours... Angies idea will indeed work but look for LED's with as high a CRI as is possible.

The 14 metre will refer to the length of the string of LED's.

An alternative is to tape your transparencies to a north facing window on an overcast day making sure that the transparency is only backlit by the sky.

The lights are encased in plastic tubing which is 14metres long. And because the tubing can be shaped it is coiled into the drawer - the plug also goes into the drawer and is removed when I need to plug it in - the length of the attached wire is plenty long enough to reach a nearby socket.

These images were taken using the lights to give back lighting.

Thank you all for lots of advise. Have bought a Nikon ES-2 which I'm anxiously waiting delivery of. And a light box which looks efficient enough for what I require.

The ES-2 works fine. I use a daylight LED table lamp as the light source. In order to cover the full slide and get it in focus you will need the 60mm f2.8 Micro-Nikkor lens. I use Aperture priority set at f16 and an ISO of 100. The results need a tidy up in Lightroom or such (brightness, contrast, colour correction etc).

Thank you Railcam - I have a Nikon 60mm f2.8 macro lens. I plan on copying using both Jpeg and RAW. The advise you give on aperture and ISO is very interesting. Thank you very much. I then have either Elements 11, Adobe CS5 or Nikon Capture NX2 to edit copied slides and negs.

Glad you find my comments helpful. I use f16 to maximise depth of field just in case there is slight curvature on the transparency, 100 ISO for best quality and Aerture Priority so that the camera chooses the appropriate shutter speed so that dark transparencies are brightened up automatically. Use Matrix metering for this.

Finally I shoot RAW and tether straight into Lightroom. 49944_1588532943.jpg
This one was done last week.

Good luck.
