I have just borrowed a calibrated Stouffer 21 step wedge mainly because I have never seen one and was curious to what they look like.
I have just created a Raw scan with Vuescan of the step wedge and also a negative. Armed with Photoshop the scanner and the step wedge, can I use it in any way to determine if the negative is well exposed / developed ?
The file which is in the Gray Gamma 2.2 Color space can also be downloaded from https://dl.dropboxusercontent.com/u/...rough-Arch.jpg
