    Question about sighting/observational drawing

    I am working my way through Deborah Rockman's book (really good btw), and I think I understand most of the "Observational Drawing" chapter. Everything except for one thing. I'm not quite sure how to scale the sighting measurement you take on your sighting stick properly so that it measures out correctly on your paper. Taking a 1:1 sighting measurement (say, 1") and drawing that on the paper is pretty self explanatory, but what if I want to take that unit of measurement and make it bigger or smaller on my paper?

    I assume I have to work with my chosen unit of measure and set some sort of increasing/decreasing ratio to it, but that seems like there is tons of room for error doing that.

    Any help or tips? Thanks.

    It isn't a fixed kind of measurement - it is just all relative and you get a feel for that. And yeah...there is tons of room for error...just have to learn to adjust and judge things. You just judge in increments of your measuring unit...and sight for landmarks...negative spaces...where things overlap, etc. Basically "sight measuring" is a way to help you focus and be disciplined about observation. It isn't the same thing as "sight-size" by the way.

    Hmm, that makes sense I guess. Perhaps it will make itself more apparent when I begin utilizing this method. Thanks Jeff.

    What is "sight-sizing"?

    From what I get, your using the actual measurement on your paper when instead you want to use it as a reference. So if a figure is say 6 1/2 heads in length you would then measure your drawing and see if it hits 6 1/2 heads. But you would base the size of the heads on your drawing, not the models actual head size, if that makes sense...and I'm sure someone else can give a better/more accurate explanation but I believe sight sizing is based on a 1:1 ratio, where you get at a distance from the subject that allows for you to take exact measurements and lay them on your drawing, as opposed to adjusting them like I mentioned at first.



    googled this image, might help or might not, eh

    sorry for any lack of clarityyy

    also sort of how jeff mentioned, its just a means to an end. try not to get too caught up in measurements and all of that, it's important but you want to actually observe and draw without needing to double check every line you make
