To scan photos, you have two scanning options: WIA and TWAIN. Scanning photos is easiest using WIA. With this simple scan method, your Canon scanner works seemlessly with ScanSpeeder's photo scanning software.
WIA provides you with ScanSpeeder's: best in the industry auto-detection, auto-splitting, batch scanning, auto-straightening, digitally tagging, and automatically saving photos as both JPEG and TIFF.
If you would like to enhance your photos while scanning, then use the TWAIN scanning method. TWAIN allows ScanSpeeder to work with Canon's ScanGear to give an assortment of tools to touch up those old photos while you are digitizing them. Unlike WIA, the TWAIN scanning method takes a little setting up, but is still quite simple to use. Let me show you...
Scan Photos with TWAIN - on your Canon Scanner
Step 1
Open ScanSpeeder:
- Click the Scanner button in Step 1.
- Select a scanner driver with (TWAIN) in the name.
- Check Advanced Mode.
Step 2
Click Scan.
Canon's ScanGear will now open. Before you begin scanning, look at the upper left-hand corner. You need to ensure that thumbnails is turned OFF.
THUMBNAILS MUST BE TURNED OFF.
Use the Normal View : 
Do NOT use Thumbnails :
Step 3
On the far right-hand of the screen, change to 'Advanced Mode'.
Step 4
In the Advanced Mode select COLOR for scanning. Even your old black and white photos, because color scanning (especially 24-bit color) delivers superior results. I also recommend selecting 600 dpi; it is the optimal dpi for archival quality and still fast enough for batch scanning. Scanning at any higher dpi is tediously slow.
As for image settings, you will need to play with this a bit depending on the photos you are scanning. I start by clicking 'Preview' to see how the photos will look without any touch up. Then I adjust accordingly. Once you play with these settings a bit you will get a feel for what needs to be done to enhance your next batch of photos.
Step 5
When you like the look of the photos in the Preview Area, click 'Scan'.
Step 6
ScanSpeeder now takes over. Your photos will be auto-detected, separated, and batch scanned. You will continue using ScanSpeeder as you normally would. For the basics of scanning, please refer to this article. Continue with ScanSpeeder by click the 'Extract Photos' button in Step 2.
In Summary - If you do not need to enhance photos, save yourself effort and time by using the WIA (simple) scan method. If you want to enhance photos, then use TWAIN following the instructions above. If you take anything away from this article, please note that THUMBNAILS must be TURNED OFF to allow ScanSpeeder to auto-detect your photos for you.
