Hi!

Which are the most common filter effects u use to edit scanned pictures?

Can someone give a short tutorial from the most common things you have to do with scanned photos so it’s less noticeable that the picture has been scanned?

Tnx!

Hmmmmm. What is your scanner doing to your photos that makes it apparent that they were scanned as opposed to a normal digital image?

I have a tip. (Working in Photoshop CS2).

If you sketch something on paper, and scan it for a website or whatever, and you want it for part of the layout, then presumably you'll want to make the background transparent.

When you try to use the magic wand to select the areas you don't want, it usually selects a fraction of the drawn line, because of it's lightness. This makes it looks quite rough.

So, duplicate the layer with the sketch on. Increase the Contrast to full.

With the second layer (high contrast) selected, use the Magic Wand tool to select the areas that you don't want. When the selections have been made, make this layer invisible. Select the first layer, the one you wish to edit, and hit Delete.

This should neatly get rid of the white parts. You may need to touch some parts up depending on the intricy of the drawing.

Note: Make sure you're using a transparent canvas :wink:.

Ooops. Didn't read the first post properly. Missed the part about photos. Sorry, I'm a little tired :oops:.

// EDIT: Try incresing the DPI for the scan. I'm asuming that the quality isn't that good after scanning it?

Hi all!

Yes, I meant photos :)
…I use Photoshop CS2


Let’s say that the photos are scanned by someone else, and I have the job to edit and cut the images.

The thing that irritate me the most are those “balls” of colours. I don't know if that's because he scanned in low quality :S

I usually do the following things:
Image -> adjustments ->
(Auto) levels
(Auto) contrast
(Auto) color

Then in filter:
Sharpen -> sharpen

(But it depends on the scanned picture)

…So my question was if someone knew something more/other stuff or a basic tutorial to edit scanned pictures

I hope I was clear enough :S lol ;)
thnx in advanced!

Try this...

Change the mode to LAB (Image > Mode > Lab Color).

Open the channels pallette (Window > Channels).

Select the 'B' channel, and gaussian blur until it looks smoother.

Repeat this on the 'A' channel and the 'Lightness' channel.

Not change back to RBG color (Image > Mode > RBG Color).

I'm not sure if this is what you're after, but give it a go and see if it improves the image.

Note: Don't overdo the gaussian blue, because it will end up losing detail on the final image, and just look blurry.

If I edit a photo it is normally on the end of AUTO(something) other wise it is a piece of are work that I am constructing and then only lords knows what I might do to it. Photos i leave alone normally.

Not a problem eSeTe. If it doesn't work, then post an example of one of these photos, and I'll have a look and see what I can do. I'm curious about it myself :?:

Hmmm. Would you problem be that the surface of the magazine when scanned was uneven, therefore making the colour uneven by adding unwanted shade in places?
