This is a massively dusty Edixa16 negative, scanned with Plustek 8200i at 4000 dpi. It shows the photo has<br>

massive dust and scratches, rather difficult to remove with photoshop</p>

Automatic scratch and dust removal function SRDX of silverfast 8 is activated<br>

The dust removal setting:<br>

dectection: bright</p>

<p>defection level 10</p>

<p>tile size 20 (maximum allowed by this software)</p>

<p>After dust and scratch removal correction, the dust and scratches are dramatically reduced to a level, with further manual removal with photoshop possible</p>

Further dust removal with photoshop manually becomes more manageable.</p>

<p>Combining silverfast 8 dust removal and photoshop dust removel, produce good result, such that<br>

a very dusty negative become rather clean</p>

<p>You haven't seen some of mine, Martin :-)))).</p>

<p>My scanner is a Plustek also (grandad Plustek 7200); it's the previous model to yours. Good machine, no dust removal though...SilverFast software was in its childhood at the time, I guess.<br>

<br />Badly damaged negatives due to dust particles (and to ever so annoying fixer crystals as well !) are a nightmare, so any Minoxer would give an arm and a leg (well, not quite) to have a tool for freeing the negatives of the pox.</p>

<p>I have been using this tool <a href="https://ni.neatvideo.com/">here</a>, for a number of years now. Very good, but the learning curve is a bit steep, due to some complexity of the tool. You need to experiment, because this piece of software is very tricky: it does get rid of the spots, but...it also can smooth your frame in a ferocious manner.</p>

<p>The answer is to check and experiment every step, until you get the gist of it. All in all, I do really like it.</p>

<p>Oh, and I have found the photo I wanted to post, in response to your Hungarian parliament pictures. It's a Minox IIIs shot, I believe the film was Rollei ATP 1.1, developed in Rollei's own.</p><div></div>

<p>Yee, that is the Hungarian Parliment at a later date than mine photo, which had skeleton over a tower,<br>

apparently under renovation at that time</p>

<p>Julian, I may give Neat Image software a trial, see how it compares with photoshop noise reduction</p>

 

<p>I find out that Silverast8 Ai Studio suite which is bundled with Plustek Opticfilm 8200i film scanner<br>

has an expert mode SRDx (scratch and dust removal).<br>

1) Select detection level 10, tile size 20<br>

2) Select "mark", all the dust and scratches are then marked in red; there are inevitably over marked<br>

areas, such as the window frames may be marked as "straight line scratches";<br>

3)Click on the Expert button, comes up two tools, a pen tool and an eraser tool; click on eraser tool to erase the unwanted marks<br>

4)click on "correction", then click scan,<br>

The result is a clean photo, with dust and scratches removed, and the rest of the image retains its<br>

original sharpness. <br>

Silverfast8 SRDx is much superior to photoshop filter>noise>dust and scratch removal tool, which<br>

applies a bluring effect according to the radius chosen across all image area; when the dusts are<br>

blurred, so other sharp image parts are also blurred.</p>
