This work mainly focuses to unveil the optical features of a black hole. Forthis objective, we utilize the metric-affine black hole geometry with theinclusion of dilation, spin, and shear charge. The Lagrangian coefficients$f_1$ and $d_1$ are the main parameters, where $f_1<0$, which differentiate thesolutions by $d_1=8f_1,\;d_1=-8f_1,\;\&\;d_1=\pm8f_1$. Based on theseparameters, we carry out this work in two cases, i.e.,$d_1=8f_1,\;\&\;d_1=-8f_1$. We forecast the detailed impact of dilation, spin,and shear charges on the optical properties of the black holes in both cases.To unreveal the optical features, we calculate horizon radius, inner stablecircular orbit, photon sphere radius, BH shadows, quasi-periodic oscillations,the red-blue shift of photon particles, effective force, weak gravitationallensing, and image magnification by using metric-affine gravity black holegeometry.
