239. Large Transparent Spots

Large Transparent Spots. These spots are generally caused by adding bromide to the developer while the plates are in the tray. A drop of bromide falling upon a plate while developing, will restrain that portion of the plate which the bromide has penetrated, consequently, a round transparent spot will result. Streaks and spots will be the result if the plate were allowed to lie in the bromide solution without rocking the tray.

Caution. - Always rock or agitate all solutions while using them. Never allow a plate or film to remain in any solution without agitating.
