Hi Joao,

I am no expert, but here are my thoughts.

Try several changes of 'development' water over a period of 30 min to an
hour. (Your print should, of course, be upside down in the tray to prevent
staining) Immerse the print in a "u" shape to prevent trapping air bubbles.
Then carefully remove the print and place it face upwards on top of a layer
of paper towels on a flat surface. Carefully remove any excess water from
the borders with some more paper tissue, ensuring that you do not touch the
delicate image area. Now use a hair dryer on low heat at a distance of
about 18 inches, dry the surface, keeping the hair dryer moving. You can
pause after a minute or so and clear the border and any highlights with
small twists of tissue.

You can, if you wish, return the print to the water tray after the
highlights and midtones are dry. This should give you greater detail in the
shadow areas.

The balance between exposure and development is something you will have to
determine for yourself. Some printers give longer exposure and use brush or
water spray to remove the unhardened gum/pigment. Personally, I prefer the
automatic development technique as described above. Probably because I am
lethal with a brush in my hands. <g>
