To emboss a fine line around a print, cut a piece of double weight paper to the dimensions of the square or oval imprint desired, and lay same on the plate glass top of the Artura Printer. If you do not use the Artura Printer, a piece of plate glass set in the work table, so it is flush with the table top, and an electric light placed underneath, will answer the same purpose.
Lay the print on top of the form and the adjustment by the transmitted light will be found quite easy. Use a bone crochet hook or needle to run over the back of the print, being careful to follow the edge of the form under the print, and a neat embossed line will be the result.
To mend a crack in a hard rubber tray, first see that the tray is perfectly dry. Then stick a piece of friction tape, such as is used by electricians, over the crack on the inside of the tray and one on the outside.
Cover the tape with a piece of tissue paper and apply a hot flat iron for a moment or two, to make the tape adhere. The paper is used to prevent the tape from sticking to the iron and is readily washed off. Trays repaired in this way will not leak and the tape will not crack or peel off.
This is not merely a suggestion, but a rule which should always be followed:
In using condensers for enlarging, it is necessary that the light be arranged so that it may readily be moved back and forth to get the proper amount of illumination.
Focus roughly for the size enlargement that is to be made. Remove the negative and move the light back to a point where the circle of light on the easel has a dark ring around it. When the light is perfectly centered, the dark ring will be equal all around. Now move the light toward the condensers till the ring disappears and the light is strong and even. The negative is again inserted, sharply focused and the exposure made.
The light should be adjusted in this way each time the size of the enlargement is changed, but the operation requires only a moment when the light is properly mounted. It must be remembered that when the lens is moved backwards or forwards the light must also be moved, if the best illumination is to be secured.
From An Artura Iris Frist By C.L. Venard.
That little girl of yesterday is a young lady to-day - her summer frocks are most becoming, it is the happiest time of her young life.
Nothing but a picture can keep her as she is. Now really - isn't it worth a picture?
