Hi group

Is there going to be a difference in the quality of a image if I scan it with computer 32bit or in computer 24bit?
Also can you guys give me some tips so I can produce batter quality images and in the same time they to be light in MB so to be fuster for downloading?
I’m using Photoshop 7

Thanks

Hi

What kind of a scanner do you use ?

If you scan paper pictures, with a flatbed scanner, you can only get about 300 dpi out of them, so don

Very soon, scanners, digital cameras, software etc. will all be 16 bit per channel, AKA 48 bit color.

Yes, you can use a scanner’s software for tonal and color corrections for a scan. But you can also disable the scanner’s software and get a raw scan first. Then make the tonal and color corrections in Photoshop, which offers a much better array of tools than a scanner’s software.

This is only true if your scanner software can export to photoshop in the full color depth. In other words; if the scanner is more than 8 bits per color (it will be), the software must be able to export a raw file to Photoshop that is also more than 8 bits per color (Photoshop will import it in 16 bits per color). Then you can make your color and tonal corrections in Photoshop in 16 bits color. If this is not possible because the scanner software doesn’t support it, it’s better to make the color and tonal corrections in the scanner software. That way the corrections are made in the full color depth, while Photoshop would do it in 8 bits. Making tonal corrections in 8 bits is not a good idea if you can do it in 16 bits as well.

Yes the software can export to Photoshop and even can make Photoshop the default software.

Of course it can. But can it export IN 16 BITS per color? If it can, you can choose to do your color and tonal corrections in 16 bits in Photoshop, and then reduce the bit depth to 8 bits per color. If it can’t, make your color and tonal corrections in the scanner software.

Point well taken.

Many books and tutorials advise to get a "best scan" possible from a scanner before editing it in Photoshop. Some even suggest to re-scan if a scan’s histogram does not look "good" in Photoshop. They fail to mention that smoothing out a scan’s histogram (or other tonal and color corrections) at a scanner is done by its software and not by its hardware. A "best scan" may very well be a raw scan, which may look ugly in Photoshop to begin with, but actually has the maximum image information preserved. Getting a good looking "best scan" from a scanner means some image information is lost due to the software manipulation, and you won’t know what and won’t be able to recover in Photoshop.

How can I find out in how many bits it is exporting?
If I look in the settings I can only see Color depth 24 bits. I’m not sure what is this.

I check your photo gallery http://www.johanfoto.nl/ and there must be something you do not tell us.
How do you produce such nice images and in the same time they are so small MB
Tell us the secret.

What do you mean? Making small images is not more difficult than
making
bigger ones.

I mean small in Mega Bites Not in physical size.

They are all produced in Photoshop, with JPEG compression between 8
and 10.

What is 8 / 10 jpeg compression?

Small physical size automatically means small Mbytes as well. Next it’s just a question of choosing the right compression, so you get a small file without loosing to much quality.

What is 8 / 10 jpeg compression?

If you save a JPEG in Photoshop, you can set the compression between 1 and 12. 1 is the worst possible quality (but very small file size), 12 the best possible quality (but large file size). If you choose 8 to 10, you get good quality and still a reasonable compression (reasonable small file size).

Yes, you can do that as well. Sometimes I do, sometimes I don’t. Save for the web doesn’t give you the 1-12 compression, but 0-100 in stead. It doesn’t really matter that much. If I use Save for the web, I use quality 70-80.

I use a Nikon film scanner (Supercoolscan 8000). The Nikon software can export in 16 bits. Apparently VueScan works with a lot of scanners and is also capable of exporting in 16 bits.

I try VueScan but just to find out that dos not support my scanner (Lexmark x75 all-in-one).
I also try searching google but with out any like.
Is it possible the scanner not to support exporting in 16 bits Any other suggestions.
