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. Any process that modulates the frequency, rate or extent of the sevenless signaling pathway. The series of molecular signals generated as a consequence of the sevenless receptor binding to one of its physiological ligands. Any process that stops, prevents or reduces the frequency, rate or extent of the sevenless signaling pathway. The process whereby a relatively unspecialized cell acquires the specialized features of the R7 photoreceptor. The series of molecular signals generated as a consequence of a transmembrane receptor tyrosine kinase binding to its physiological ligand. Any process that activates or increases the frequency, rate or extent of the sevenless signaling pathway. The process whereby the R7 photoreceptor commits to its cell fate. The R7 receptor contributes the central part of the rhabdomere in the apical parts of the ommatidium. Any series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell, where the receptor possesses catalytic activity or is closely associated with an enzyme such as a protein kinase.
