Scanning a sketch issues

Question

Hi friends ,
I wanted to scan a sketch using photoshop , so I went to File>Import>Wia Support , Photoshop recognizes my scanner
Canon lide 110 , I choose Black and White 300 dpi and scan it .
Now I got the sketch in bitmap format openned, the problem is  i can do nothing except rotate the image , every panel fonction is grey out , I can't even make a background copy layer....
Did i miss a step ?
Thank you !

Basically the same as Mylenium's Color Mode suggestion: Image>Mode and then look down the fly-out menu, to just below the little divider line. There you will see 8-bit per channel, 16-bit per channel, 32-bit per channel, etc.. If you need an Effect/Filter that is not available to a higher Bit-Rate Image Mode, just drop down to a lower one.
I like doing what I can, at a higher Bit-Rate, and then, when done, will drop down, for those Effects/Filters that are say, 8-bit only.
Good luck,

PS - if you do not find that you are limited with your scanned Bit-Rate, do not bother changing it - unless you need to Save_As, and the format needed does not support the higher Bit-rate.
