I think some are confused..

What scanner you using ?

This seems to be a repeat of a post elsewhere in the thread - see my reply there.

Epson Perfection Photo 1670. Flatbed with a scanner in the lid.

It might not be as good as a dedicated scanner (although TBH when I borrowed one and tried it there wasn't much difference) but it will scan anything up to the size of the light, which is about 6x2. Inches. I always used to take 126 slides, and most dedicated slide scanners don't like the square image.

Also the price was good (Freecycle!)

The Canon S2? No, the shooting modes on mine are:

? Portrait ? Landscape ? Night Scene ? My Colors ? Foliage ? Snow ? Beach ? Fireworks ? Indoor ? Night Snapshot ? Stitch Assist

Since the discussion was camera phones, I was assuming he meant the Galaxy S II

You must be a very patient man. I started to digitise the several thousand I've taken over my life, but gave up after a few hundred.

They seem to average about a minute each. I can usually answer a news post between each one :)

I wasn't that pleased with the results, either. The scanner seems to like dirt.

(Epson Perfection V300 Photo).

I have a flatbed with an A4+ transparency lid. It will do 5 off 6 exposure strips of 35mm at a time (or 16 mounted slides IIRC). Its not exactly quick (maybe the PC wasn't as I haven't used it for a couple of years) but I did a few thousand negs using it. I could load it up and start a scan and do the same again when I got home from work.

So it is an old scanner then?

Not so bad with a slide feeder - load up 50, leave em running overnight...

Mounted slides are quite easy compared to negative strips.

They are easier to handle and the software can find the black border easily and remove it.

IME with strips there is always a bit of leeway as to where the exact edge of the picture is in the holder and sometimes needs a bit of pre-scan and adjustment if you are to avoid cropping.

I normally do slides in a dedicated film scanner, but I can also do transparencies on my flatbed. It has predefined templates for marquee selections that match the supplied neg strip holders, however there is nothing stopping you tweaking the supplied template to make each selection a little more generous and saving it as a new template. It means you will need to manually crop later, but at least you can do that fairly quickly on a batch.

So why is it my camera can take pictures click click click several times a second (until the buffer fills, and it has to write to flash) and yet a slide or flatbed scanner takes a minute? Hasn't anyone built a scanner with a DSLR sensor behind it instead of a strip?

Scanners and cameras use different sensor types. A scanner will have a linear sensor that is physically scanned over the subject rather than a

In my slide scanner you can select what options apply to each scan. That means you can have a resolution up to 2700 dpi (optical). It can do digital defect removal, which requires scanning at several focus positions to work out what is a scratch or spec of dust on the surface of the transparency and what is actually something recorded on it and then doing some nifty signal processing. Finally it can do oversampling which may require the image to be scanned up to 16 times, and the results averaged[1]. This dramatically reduces the noise in the dark areas of the scan and overcomes one of the weaknesses of the CCD sensors used in scanners that causes them to be more noisy when dimly illuminated.

The result is a quick scan is around 20 secs. A full on all stops out scan with all bells and whistles turned on is about 10 mins per scan.
