Hello...my name is Ashley and I am having a little trouble scanning and tweaking my images.  Confused

My setup is:
Canon CanoScan N1220U
Adobe PhotoShop 5.0LE (Limited Edition)
iMac DVSE 500MHz

I usually scan at 600DPI (Scanning at 1200dpi takes 10-15 mins depending on the photo)

Then I save the image in my scanning software as a PICT file. And re-open it in Photoshop LE.

I then go and do the unsharp mask (http://www.x-plane.org/users/goodbye/Unsharp.jpg)
with the setting shown in the image.

After the unsharp mask I do one sharpening, then re-adjust the image to 1000 pixels across.

After re-adjustment to that size I sharpen once more. However, in Photoshop LE there is no "Degrain" function and this is a bit of a problem.

The result is something like this http://www.x-plane.org/users/goodbye/JA8088.jpg

If there is anyone who can help me or give advice please tell me so.

Thanking you,
Ashley Cripps
 Big thumbs up

Well, first of all, when I follow the link you provided, I get the following message: "You don't have permission to access /users/goodbye/JA8088.jpg on this server."

About your scanning question:

You will never get as good pics by scanning prints, as by scanning slides or the negatives. However, a few tips might help:

- Be careful with sharpening. Instead of sharpening, try to use unsharp mask.
- Apply the unsharp mask after resizing.
- Avoid the noise reduction (that's the "degrain", you're looking for), os use it only for specific areas, like the background or so.

Perhaps somebody else has more tips.

And what exactly is the problem using a Mac? Perhaps I don't get the point ....

Gerardo,

It's a long standing joke between myself and Ashley.

Even if it takes longer to scan the image to get a better quality, it may be the only option you have if you want the best place to start.

Photshop is a powerful piece of software when used properly. Try this method for sharpening: With your image open select IMAGE, MODE, LAB COLOR (Photoshop's native mode). In LAB mode select the LIGHTNESS channel from the small window. Apply your sharpening to that channel with the unsharpen mask values between 100-120, 1.5, 1. Applying smart blur filter to one of the other channels in this mode can also help reduce artifacts, especially with digital pictures and in the blue areas of the image. Experiment and see which works best on each image.

When all adjustments are completed in LAB mode switch back to RGB color from IMAGE, MODE.

Adjusting LEVELS yourself is often better than having PS do it for you automatically. To adjust the levels select LAYER, NEW, ADJUSTMENT LAYER. Select LEVELS and use the sliders to achieve the best look. Open new adjustment layers to change the look of the image, but try to limit how much you do, otherwise you risk ending up with it looking worst than before you started. Before you save in JPG format you must flatten (combine) the layers with LAYER, FLATTEN IMAGE.

There are some good tips on using Photoshop at the following link

I hope this helps.

hahaha, thanks Bron, so if I move to Canberra and use a PC I will be right?

JT8D: My version of photoshop (5LE) does not contain LAB mode or a new adjustment layer.

Well, if you moved to Canberra and used *Glenn's* pc you would be OK as his is tweaked for Photoshop etc.

 Laugh out loud when can we expect you?

Dammit Ash,

I was here all day, you must have mixed up the address (typical)

 Laugh out loud but if you hang out to long at Fairbairn the RAAF elephant trackers will pick you up and I heard that "hightened level of Defence activity" means full body searches.
