Scottish Photographic Federation
Founded in 1903, the Scottish Photographic Federation (SPF) is a non-profit-making body which includes in its objects the discovery, promotion and protection of amateur photography throughout Scotland, and is the only body recognized by international agencies as representing the interests of Scottish Camera Clubs on a national basis. Most Scottish Camera Clubs are affiliated to the SPF and thus participate together, and against each other, in inter-Club, National and International Competitions.
I agree with Debbie P. This paint looks terrible on glass. Streaks, different colors. I'm attempting to paint a State Seal on stained glass to make a badge for my son and at the rate it's going it will be 2 years before it's painted good enough to use. Everything she said about the brush stroked and overlapping areas is true for me. Not a happy camper with this product.
As a cartoonist, I've found only the 100 nib to be one
that acts like a brush in that it gives me the thick and thin line that I desire, and a very thin line as well. It
handles well and is very flexible.
