This compensates for the absorption of light by the filter. This process is unnecessary with TTL metering systems as long as the filter is attached during the metering process. Filters are colored glass, gelatin or plastic disks, which modify the light passing through them, mainly in terms of color content. They can be used at the camera or printing stages. Finality development is prolonged development, reducing silver halides affected by light to silver until no further image density improvement occurs.
Finder is an abbreviation for viewfinder .
Fine grain developers are film developers which help to keep grain size in the photographic image to a minimum. Finlay, Charles died 1936. Invented the mosaic screen additive color process known and marketed as Finlay Color. Depth of field is practically infinite and focusing is not required. Fixation also known as a fixing bath, is a chemical bath which converts unused halides to a soluble silver complex in both negatives and prints, making the image stable in white light.
