:: 2007 - Ricoh Caplio GX100 ::
Back in mid-2007, having convinced myself that the very limited use I make of my DSLRs couldn't justify getting
an ultrawide zoom, I chose instead Ricoh's pocketable GX100.
Turned out to be a great little camera, especially in cities etc; very convenient and capable of taking fine pictures,
so money well spent. Excellent lens (f/2.5 at 24mm, zooms to 72mm), with IS and a 10MP sensor that produces
RAW files in Adobe's DNG format plus manual controls, overrides etc...
When fitted with the Konica Minolta ACW100 adaptor (0.8x), it widens to the equivalent of 19mm.
:: Why scan? 35mm slide copying with your digicam ::
A few examples of the results from digitising several thousand transparencies, using a
Nikon CP 5400 digital compact camera as the basis of a homemade slidecopier.
The holder was put together from a few metal oddments, some card and electrical tape
(click on the first image for details), of a size that held the slides about 2.5" from the
camera body, where they'd just fill the frame with the lens zoomed to its 35mm setting...
at which barrel distortion was reduced to the minimum.
Shot using 5MP Fine setting in Aperture priority mode, mainly at ISO 80.
Illuminated by daylight, reflected from the ceiling of a sunny terrace, using a custom white
balance that was set at the start of each session... and sometimes rechecked.
Many of the slides (which I've kept) were on high contrast film, or taken with a polariser,
so reshooting with reduced saturation and contrast was often necessary and, most times, a
quick clean with a soft lens brush.
After cropping, the JPG files are about 1.33Mb, and they average some 2400x1600 pixels
(enough for decent 8"x5" prints) - roughly 85% of camera's full pixel count in 3:2 mode.
Post-processing workflow using - at the time - Photoshop Elements 3 (WinXP) went:
- Remove any barrel distortion with the "Lens Distortion" filter from photo-plugins.com
- Rotate as necessary, crop to remove slide mount margins and other unwanted areas
- Clone stamp or healing brush to remove dust marks
- Improve brightness range with Levels or 'Shadows and Highlights'
- Unsharp mask, then "Save As" at JPG Quality 11
Time for about 50 slides (exposure, uploading, editing and saving) averaged 3 minutes each,
but what worked best was shooting continuously while the weather and light were good, and
then processing them in the evenings or when the light wasn't suitable!
:: DPR etc ::
Examples, reworkings and the like - not necessarily all of the originals are mine..
:: Sample scans from the Epson Perfection V370 ::
First group of these were scanned at the 2400 setting, from 35mm colour negs shot with a Canon T70 and standard zoom.
The remainder are doubled - with the negs scanned at 2400 and the corresponding prints, some 5" * 3", at 600. No retouching applied!
