so this was my second plate from last term:
but I'm getting ahead of myself
my series of images in this case is the tideline on the river - at the top left of the plates you can see some stones on the shore, in the middle at the top are a few boats bobbing about as the tide comes in, and the lines moving from right to left across the plates show the tide coming in and filling up the pools created by undulations in the sand banks. . . in the the plate on the far left, the tide is out and the shore exposed and in the plate on the far right the water is at its highest
I have started (visually speaking) with only a few very simple lines, I will develop the image later; but at this point I only want to etch those lines onto the plate and then take a quick print to see how the lines work (visually speaking). . . so, the plates go into the acid for about twenty minutes:
you can tell if the line has been etched into the plate by gently scratching across the line - if it's deep enough, your fingernail catches (take it out of the acid first and rinse it off - don't put you hand in the acid to do this!)
when the acid has "bitten" into the plate sufficiently take the plate out of the acid and clean off the hard ground with white spirit (different waxes/resists are cleaned with different things) (things, oh how techincal of me!)
the following photo shows the plates: simple lines etched thru a hard ground resist, one session of twenty minutes in the acid, cleaned off and ready for the next stage
(not a great photo, as a really annoying woman was standing in the light, staring at me. . . *deep breath*); the following photo is a closer view of just one plate - boats at the top in the middle, slabs of stones in the top lefthand side corner (the stretch of the river near where I live has many stone slabs on it shore), edge of the shoreline on the right and a couple of tidalpools of water in the shingle in the middle. . .
