The methods previously described are readily applied to enlarging.

The trial exposure must be made upon a portion of paper placed in position upon the easel, the highest lights being as before selected for trial.

It is a peculiarity of enlarging that the negative behaves, when compared with contact printing, as though it had been developed much longer, consequently a longer scale of the paper is required to give good results. Even with the most rapid paper and the longest scale obtainable, most negatives will be found too strong to give the best possible results, and the bichromate method will then be found particularly useful. After exposure simply follow the directions previously given under contact printing.

GENERAL REMARKS. If before taking up general printing, four negatives are selected (or, better still, purposely prepared by exposing four plates equally on the same subject and developing for varied times) as stated in Table 3, and experiments made so as to obtain both good contact prints and enlargements, using the three papers selected and the control with the bichromate of potassium, the set will be of great service. It will make a standard with which to compare other negatives, and by means of which it will not be difficult to select by inspection the best method of working. The bromide print is probably the most lasting of all silver printing processes, and the ease with which it is produced without recourse to daylight makes it specially suited to the requirements of the amateur.

From being the most exacting of all processes as regards the negative, the method of control of gradation described, adapts it to both weak and dense negatives, whether used for contact printing or enlarging.
