Hi Derin,
I am also of the opinion that you should keep a high res master production scan that surrogates can be made from in the future in most situations.
I don’t want to be picky but I think there may be a little confusion over the way Digital ICE works in reference to the review you posted, in the review "where it removes windows etc" it is talking about a digital dust and scratch removal 'filter' which has to interpret the scan and then removes items. Digital ICE technology works differently by using an infrared scan pass to locate foreign bodies (dust) on the transparency and also scratches and holes in the emulsion where the IR passes right through. It does not interpret the scan, rather it locates areas where no photographic data from the emulsion can be recorded either because it is no longer there or is covered by grime. The accuracy and the way it paints in that missing data is a different discussion but as a tool for cleaning up the majority of dust it has worked very well for me in the past and can save hours of photoshop work if you are trying to create a commercial/useable image.
I still agree with most on this subject that there is no single answer to the original question. I think collections need to be assessed prior to digitisation and a decision can be made about why the collection is being digitised. Any tools (ICE etc) used should be documented so as to not mislead researchers in the future as Damian refers to.(24/03/14)
My personal view on in house produced photographic material of events and galleries/exhibitions etc depends again on why it is being digitised. If it is just to preserve a record of what is on the slides so they can be dumped and save space in an office then I think a bit of digital ICE and some basic levels would be fine but historical analogue photographic material (not including prints) should be treated very differently.

Subject: Re: Scanning slides / digital ICE technology
I would not trust digital ICE to carry dust and scratch removal, see this review http://www.photo-i.co.uk/Reviews/interactive/Epson%20V700/page_9.htm where it removes windows in the picture and leaves some dust behind. The ideal would be to retain an as-is scan. Without a consistent, calibrated and characterized scan, there is no way to use the image as a reference for the image, in case it is needed for conservation purposes. A digitally restored variant that had color, scratch, fading corrections and such could be stored and delivered separately with clear metadata to mark it as such.

Hi Becky, indeed it is a good question and one which is a constant topic of conversation for us.
We, like previous respondents, have adopted the reasoning that dust and scratches would not have been on the glass plates/slides/negatives etc. to begin with so we do remove the most obvious ones if they are detrimental to the image, especially if the image is to be used for publication purposes. We also adjust the colour balance where appropriate if the original has faded over the years.
I would agree that it is really up to the individual organisations how they wish tackle this.
Regards,
Anne

Hi Becky,
This is a good question and I can see that you're receiving a lot of good advice from other colleagues. I think ultimately it comes down to whether the original image is considered an object or not and whether the removal of dust and scratches in destructive or not. I have in the past worked on photographic collections and using ICE was never considered as one had no control over what was being removed during scanning. I hope that helps.
Regards,
Matt

Subject: Scanning slides / digital ICE technology
Dear All,
If anyone can help I would be enormously grateful. We have been discussing our views and our working practise in the use of digital ice technology (automatically removing scratches using scanning software).
Does anyone use digital ICE technology when digitising slides a) within their photographic collections that have been donated and b) when digitising slide collections of events / site visits that have been photographed by staff within your organisation? If so, do you store 2 copies one with Digital ICE and one without?
Considering in-house photography, we wouldn't dream of removing scratches from old glass plates that have been digitised, but are considering doing it for our slides, I suppose the real question is, at what stage do internally produced photographic collections become objects that need preserving in their own right? Also does anyone do colour corrections such as removing a cyan cast when scanning internal slide collections?
Hopefully it all makes sense!
With many thanks in advance,
Becky
