338. With this developer, working as it does quite rapidly, care must be exercised that you do not over-develop. Examine the plate frequently. It is a good plan to provide yourself with a washing tank; fill it with water, and when you judge a plate very nearly developed, place it in the tank of water, and allow it to remain for fifteen minutes. If you have other plates to develop, proceed and develop all you have, but place them all in the tank of water for a short while before transferring into the fixing bath. You will be surprised to discover how much the plate will develop in the water, and the developing will not be harsh, but soft, mellow and round. The half-tones will be full of detail - the shadows crisp and snappy.

339. In case of a plate lagging in the developer, indicating under-exposure, place it in the tank of water for ten minutes at a time, then return it to the developer for a while, and if it still appears weak, again return it to the tank of water. The temperature of the water should be about sixty-five degrees. Many times a considerably under-timed plate can be treated in this way, and a splendid negative made of it.

340. In case of over-exposure - the plate flashing up quite quickly - it is advisable to provide yourself with a tray of water containing several drops of bromide, and place the plate in this solution for five minutes. This will restrain the shadows, and when returned to the normal developer the plate will develop evenly and round up, becoming more crisp as it continues developing. In case the plate was very much overtimed, and not checked soon enough, then you will need to develop quite dense, and finally reduce with red prussiate reducer. For formula, see instruction on Reducing. Negatives that are just a little dense, and perhaps a trifle hazy, can be greatly improved - the shadows cleared and strengthened -by immersing the negative, after thorough fixing, for a few minutes in a weak red prussiate of potash reducing solution.
