White-light images, centered at λ6708A, were obtained at the Swedish Solar Telescope, La Palma, on occasion of the 1994 May 10 partial solar eclipse. From the recorded information, 5 frames showing several pores together with the moon's limb were selected for detailed photometric analysis. The observed intensity profile of the moon's limb projected against the solar disk was used to derive, from each frame, the Point Spread Function of the atmosphere + instrument to restore the images. The characteristics of the obtained PSFs -low noise and precise determination of the wings far away from the core- enabled us to avoid arbitrary assumptions about analytical approximations. The FWHM of these functions was typically 0.47". Several bright features were identified in one of the pores. After determining the photometric parameters of these fine umbral structures their link with the population of the bright features in the umbra of evolved spots is discussed in the framework of the dependence of sunspot properties on the spot size.
