I recently have been trying to work on getting better values but have ran into somewhat of a road block...I noticed in Photoshop there are many ways to convert your drawing into greyscale. The problem is that I noticed each one seems to do it differently. Is there some sort of set way that can make sure I'm not getting a distorted greyscale?
I donīt know if the following link answers your question but it definetly is woth reading.

Either (1) switch to Grayscale mode, or (2) switch to Lab Color mode and then use the Desaturate adjustment.

Wow! Thank you all for such a quick response! I'll defiantly read over your link bjoern3000. Also thank you both briggsy@ashtons and Dile, these both seem to be working nicly!
I'd suggest duplicating the layer first. Then greyscale the duplicate make any value adjustments nessisary. Then set the duplicate layer mode to "luminosity". Merge the layers and you'll have the original color picture completely value adjusted.
Another easy method for grayscale is to have a black filled layer at the top set to color, saturation or hue and then just turn it on and off to check. Can't remember where I found this trick but i've found it to be really useful.
Shorinji knight and gunnersquad: I'd just add that both of those tips work a bit more accurately in Lab color mode (which uses Lab L for "luminosity") than in RGB mode (which uses luma Y).
There's an even easier non-destructive way. Go to View-> Proof Setup. Under "Device to Simulate," click the dropdown menu and select Gray Gamma 2.2 and hit OK.
Now when you press Ctrl-Y, it will toggle you to Proof Colors mode, which lets you see what your composition looks like in grayscale without switching to Grayscale color mode or messing with adjustment layers.

Yes, thank you neonnoodle! That seems to work perfectly in RGB mode as well as Lab Color mode. Dose's method is close but like gunnersquad's converts to a grey of the same luma (Y) in RGB mode, so there is a bit of relative darkening of high-saturation colours.
