The A-kla Daylight Loading system, patented by A.A. Brooks, was a method of transferring plates from their packing to a dark-slide and to a developing tank in daylight.

Two plates were each enclosed in metal trays covering their sides and backs. The two plates were then placed with their sensitive surfaces together, the two trays pushing together similar to a very shallow box which was then light-tight. In this form the plates were packed and sold. Attached to the back of the trays was a wire loop. In use two A-kla dark-slides were clipped together with their draw-slides removed. The two sensitive plates were placed in the back of one of the dark-slides, from a small door in the other dark-slide the wire loop was pulled which separated the two plates leaving one in each dark-slide. The draw-slides were then returned and the slides separated. After exposure the two plates were re-joined by again attaching the dark-slides together.

Developettes were provided with the plates for determining the required development time. These were pieces of sensitive paper partly fogged and partly coloured, and were developed along with the plate until the fogged area matched the coloured.

For single metal slides a slightly different arrangement was used where an intermediate transfer box was loaded with sensitive plates which were subsequently loaded into the metal slides.

A-kla produced their own range of cameras from around 1911.
