How to scan old photos?

You want to scan lots of old photos. Some of the photos need to be retouched. I would like to scan a photo so that there is no question about re-scanning.
The prints made on different types of paper (matte, glossy, textured). Some of the photos are damaged (cracks, breaks, bruises, spots).
What scan settings advise (hand Epson Stylus SX130)? What image format are using for storage? What Niihau use in various types of photographic paper and damage to the imprint, to facilitate the retouching?

Recently scanned ALL of the albums. Went a couple of weeks (several thousand photos)

From experience:
Scan with the maximum resolution - there really is NO need. To pregledavate pictures once in ten years, and it is important to see what is there and not look out of Shcherbinka and moles. So at 600 DPI enough above the roof for all the usual family photos, and for photos made with a digital camera is 300 dpi for the eyes.

Separate pictures of the restoration, it is possible to try otskanit with higher resolution, of 1200, neatly pressed, but you need to understand that if you start to restore themselves, through 30-40 pictures you get tired of it, and you will understand that it is not so important super-quality. Therefore, think carefully whether picture extra effort, or in a common stack. Rare Studio photos, not done on a digital camera can also be otskanit 1200.

Slides, filmstrips - 1200 is enough. a little blurry, but actually slides do not give too much resolution, i.e., scanning a slide at 2400, especially quality not added, and the size - at times. Then it is just uncomfortable to watch.

What you need to pay attention:
1) the location of the photo on the scanner. The smoother put than careful to close the lid, the smoother the picture, it is easier to cut and less work.
2) Immediately come up with cataloging. While the photo is scanned, you can rename it, put in the right directory.
That is - not very.
серый_альбом/фото10.јрд
белый_альбом/фото10.јрд

And continuous numbering - much better, especially if in the future the pictures will be shifted from folder to folder.
серый_альбом/фото10.јрд
белый_альбом/фото20.јрд

Ideally, if the album was conducted correctly, homesandland. If it's hard, for example 2001-xx-xx-01.jpg will be at least a year.

In scanning prints nothing tricky there, with the usual office scanner the more. I would advise to find the film and scan them on a film scanner there and the quality will be higher and get some unpublished footage.

Last year I scanned all the parent photo archive of slides and negatives. Before to share the experience, to quote the answer of Sergei Alexandrovich.
From experience:
Scan with the maximum resolution - there really is NO need.


From experience:
Scan with the maximum resolution is really NOT necessary. The reason of scratches and other imperfections that occur in almost every frame. When you're scanning at a low resolution, and then removed the defects, the picture quality suffers greatly.

I scanned on a Plustek OpticFilm 8100.
The scanner can scan negatives and positives in the flesh resolution up to 7200 ppi.
The scanner is attached to a special frame holders for film. Every film (which is usually 36 frames) cut into pieces on 6 frames and inserted into the frame. After scanning, the film will be slivered.

Scanning in color and b/W negatives
Don't know what there is obtained after scanning at 1200 ppi ( from the words of Sergei Alexandrovich), but the result seems to want users to "kontaktika", but no more.
The scanner is able to do a quick pre-scan, after which it becomes clear whether or not to spend time scanning the frame in high resolution. My eye is not a diamond, but the difference in detail between scans at 2400ppi and 3600ppi notice. To scan at 7200ppi makes sense when there is a rare frame where a lot of scratches. The scanner comes with special software SilverFast Ai Studio, which you can use to remove scratches in smart mode. In practice it turned out that with scratches all cope better Photoshop.
The algorithm for processing color negatives:
1) Pre-scan, visually determined by the value of the frame.
2) If the frame is serial, then scan at 3600ppi. If the frame is rare and valuable, then scan at 7200ppi. No optimizations means SilverFast Ai Studio is not running, just saved raw to TIFF.
3) In Photoshop do color correction, change the contrast and remove scratches. If scanning at 7200ppi, after processing to reduce the resolution of 3600ppi and save.

On B/W negatives detailing above, than on color and stronger noticeable scratches.
As for slides (positive), then it is possible to scan at 2400ppi.

A little about the size and permissions:
7200ppi in TIFF format in color => scanning a single frame of 3:56 min => resolution 10260х6844 => file size is ~200 MB.
7200ppi in TIFF format B/W => resolution 10260х6844 => scanning a single frame of 3:56 min => file size: ~68 MB.
3600ppi in TIFF format in color => scanning time of one shot 1:25 min => resolution 5130х3422 => file size: ~52 MB.
3600ppi in TIFF format B/W => scanning time of one shot 1:25 min => resolution 5130х3422 => file size of ~18 MB.
