It is probably due to the same reason that RC papers need a very short wash. The resin papers coating before the emulsion is applied is impervious and does not allow liquids to soak in. The surface of fibre papers is porous and allows liquids to soak right into the body of the paper underneath the emulsion layer.

Your comments make a lot of sense Tony.

It's the way I was taught some sixty years ago using watercolour pigments and I've never found need to change it except that instead of dampening the brush with saliva (no H&S then) I dampen it using water with a tiny drop of wetting agent then wiping the brush on tissue before picking up a touch of pigment. However, whatever works is the right way in my book, fortunately I use a diffuser enlarger now so spotting is almost a thing of the past thank goodness. |

I meant to ask previously Keith, what is the pigment exactly, that you use?

As mentioned earlier I use watercolour pigment Terry, the solid cake variety that comes in little 'pans' of colour and the one I use is 30+ years old. Not very 2st century but it does the job on the very rare occasions when it's needed and frankly, as photography is now only a hobby, it's not something I fret about. I was simple curiosity that piqued my curiosity and now thats quenched I'll exit stage left.

One final question though - I have tried various watercolours, including ones for colour prints, which contain black, but they have always sat on the surface of prints and when you start looking they pop out at you. Does your spotting / paints not do that? Do you use the paints as is, or do you add something to them? Terry S |

I have a small dish on which the colour has been painted on at various dilutions and then allowed to dry and I have a small eye dropper bottle of distilled water with a tiny drop of wetting agent added which I use. In use I touch the tip of the brush into the water and wipe off the excess on a tissue. I then pick up a tiny amount of the dried colour and check the shade on a scrap piece of the same paper. It has to be slightly lighter than required because I build up the tone gradually. It's old school I know but it works for me and it has the added advantage that if I go too far then the pigment can be lifted off with a damp brush before it dries and another attempt made. Once dry the surface coat on the emulsion seems to hang on to the pigment and it becomes permanent as far as I can tell. Since I moved on to a diffuser enlarger spotting has become a rarity and it must be two or three years since I last had need to do any thank goodness because my ancient eyes with their myriad of 'floaters' make it really difficult for me. |
