Scanning Notes - How are images are created for this web site?
Creating the scans for this web site.
I have been asked how I scan my 35mm film material on several occasions and as a result I thought I would write some notes on the subject to guide others.
The scanner I use a Plustek Optic Film 8200i scanner which has infrared dust removal. This dust removal feature is about 75% accurate in removing dust spots and blemishes on colour slide, negative and chromogenic black and white film. Any remaining traces of dust, if it exists on an image, is removed with Photoshop.
The dust removal feature does not work with silver based monochrome film and has to be switched off.
The Plustek 8200i scanner is supplied with Silverfast software. However, after reading several recommendations online I decided to buy the Hamrick Software program VuScan. This is a try before you buy program which can be downloaded from the internet.
Slides and negatives are scanned using the VuScan software set at 7200dpi and saved into DNG format which produces images sized approximately 97xx by 64xx in size.
The output size of the images is set to A3.
The resulting DNG images are then processed in Adobe Photoshop.
The high-resolution scanning gives some leeway for cropping and recomposing images.
Once edited in Photoshop images are then reduced in size to 7000 by 4000 and saved as JPG files with minimum compression.
The images are then uploaded to the web site.
On the rare occasions that large format slides (6x6) or prints need to be scanneda Canon 9000F flat bed with film scanning capabilities is used.
I hope this information is of use for those wishing to scan their own collections of images.
