Argh, I just wrote this really long post about glazing and Firefox crashed (again). Why is this new Firefox crashing all the time? I'm really pissed off--

errmm-- where was I?

well, this is about glazing and maybe it should go into the Fine Arts of Critique area (feel free to move)

Here is what we have so far about Glazing:

DSIllustration used glazing in his werewolf tutorial http://www.conceptart.org/forums/showthread.php?t=45901(below (image 1 below)


From what I understand so far, glazing is a process by which you apply these tansluscent layers of coulour over an underpainting, the layers add up and create a luminescent subtle effect. Glazing was used a lot in painting until the late 19th century.

Here is a link explaining the process a bit more: http://www.artisticforum.com/ArtFacts-06_03.htm

It says that it is neccessary for each layer to dry completely before adding a new layer.
DSIllustration uses opaque paint directly on the wet glaze. So there seem to be different approaches.

This website says that you need something like 9 layers to get the full intensity of coulour http://painting.about.com/od/oilpainting/a/GeraldD_glazing.htm

Here is some more info http://painting.about.com/od/oilpainting/a/glazing_FAQ.htm
http://painting.about.com/od/oilpainting/a/Glazing_Tips.htm

This seems to be a good tutorial. Here, the underpainting is grisaille (b/w). http://www.wetcanvas.com/Articles2/32418/530/index.php
Can any colour be used for the grisaille underpainting? I used dark brown.

What I'm trying to achieve is something like image 2 (below)
Where I am at the moment is image 3. I guess I have a long way to go ;-)

Questions: Should the thinning medium for the glazes feel more oily or more turpentin-ish? How much medium should I use and when do I know that I have used too much? (I'm using the Artisan painting Medium for water soluble oils, it is recommended for glazing but it feels pretty oily)
I have some problems with adherence and coulour in the area of the nose, the new colour doesn't stick porperly and the lighter areas are hard to cover with the darker glazes. Can such technical mistakes be remedied, or will they come through every time I try to correct them?
Is there a video showing glazing somewhere? It's much easier to "steal" technique when I see poeple doing it live.

you should also check out a book called Traditional Oil Painting by Virgil Elliott. It has a lot of stuff about glazing in there and some of the traditional oil techniques, as well as info about supplies and things.

I've been taught to use a 50% turp and 50% linseed stand oil mixture, which I think is the most common/basic mix. I'm not sure about all the other mediums, but I think those are for more advanced glazing so I wouldn't worry about it now.

As for the thinning medium, it should feel about 50% oily and 50% turpentin-ish... ;)

When you mix the pigment in with the medium, you should only use a little bit and you should try to use more translucent pigments, (for example, Alizaron Crimson is more translucent vs. Whites are generally more opaque) When you apply it onto your painting, you should apply it pretty thinly, if you glob it on there, I've heard that it can slide down overnight.

I hope that helps. And, I'm a total art noob. I only started oil painting last year, so if I got anything wrong, anyone who knows more ::coughelwellcough:: feel free to correct me.
