The process whereby the R8 photoreceptor commits to its cell fate. The R8 receptor contributes the central part of the rhabdomere in the basal parts of the ommatidium. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a compound eye 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. The process whereby a relatively unspecialized cell acquires the specialized features of an eye photoreceptor cell. 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.
