Two forms of enlargers have been intro-duced into this market, each with its own merit. One which is winning favour employs a method of diffused lighting, the other develops the use of condenser lens.
Either can be purchased in a vertical model, which takes up less room than the older horizontal enlarger, and automatic focusing ia an additional modern refinement common to both. This means that the operator can place the film in the enlargcr, and whatever size of picture he wishes to make, he has only to raise or lower the instrument to give this size and the picture is focused and ready for the exposure.
The particular advantage claimed for the dliffused-light model is this: any defects in the negative, such as scratches or finger marks, are, by the scattered light, not transmitted to the print. With the condenser model these defects are, by the snlargers concentrated beam of light, intensified. But if the defects are brought out, so also is the detail.
The condenser enlarger gives brighter, crisper, and more contrasty prints than the model with a diffuser can ever produce. As wfth so many of the instruments and materials offered to the users of cameras, the choico of an cnlargcr will be decided by the users preference for contrasty or soft enlargements.
