The specialization of organization of a photoreceptor, a cell that responds to incident electromagnetic radiation, particularly visible light. An example of this process is found in Drosophila melanogaster. The process whereby a cell becomes capable of differentiating autonomously into a photoreceptor cell in an environment that is neutral with respect to the developmental pathway. Upon specification, the cell fate can be reversed. Process by which a cell becomes capable of differentiating autonomously into an R8 cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The process involved in the specification of cell identity. Once specification has taken place, a cell will be committed to differentiate down a specific pathway if left in its normal environment. The process whereby a cell becomes capable of differentiating autonomously into a neuron in an environment that is neutral with respect to the developmental pathway. Upon specification, the cell fate can be reversed. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a neuron. Process by which a cell becomes capable of differentiating autonomously into a retinal cone cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments.
