Basically you purchase an IT8 card that you then scan, and finally run that scan through a program that will create a profile for your scanner. This profile will automatically color correct your scans when attached to them as long as you scan them in with the same settings that you scanned in the IT8 card. It’s an excellent way to get an accurate baseline for all your scans and make them require much less work in the post-editing phase. |

This basically just means that the scans we create are completely untouched except with easily reversible changes that don't result in ANY quality loss. It's a pristine no frills straight from the scanner image which provides us with a consistent baseline to start from. When we scan images we make sure we don't aggressively crop and cut off parts of what we're scanning, it's best to always leave a small border around the image so nothing is lost. We turn off all scanner software enhancements and color corection for our RAW scans as they will effect the image. | + | You'll see that we refer to scanned files as RAW quite often.

We don't straighten our RAW images in Photoshop or any other software suites (outside of **lossless** 90 degree rotations) as it will alter the scan. We basically only attach an IT8 profile if we have one, and save it to either ZIP compressed TIFF Format or as a PNG. We want our RAW files to be lossless and as pristine as possible. |
