This last sweater I unraveled was a breeze since it was knit with bulky yarn. The hard part was getting a picture of it that wasn't blown out to nuclear proportions.
We've been talking about it in the Yarnographers Group on Ravelry. For some reason, digital camera sensors flip out when it comes to red, so in order to get decent shots you need to under-expose by a few clicks and preset the white balance. Photoshop irons out the rest of the usual kinks like brightness, saturation and all that jazz.
