11. There are higher order chromatic aberrations , such as the dependence of magnification on color. 12. In 1733, he succeeded in constructing telescope lenses which exhibited much reduced chromatic aberration . 13. Several types of aberration affect image quality, including spherical aberration, coma, and chromatic aberration . 14. Vignetting, barrel distortion and chromatic aberration are also problems that are difficult to eradicate. 15. This relies on the exploitation of chromatic aberration ( wavelength-dependence of focal length ). 16. Chromatic aberrations are caused by lens's refractive index with wavelength.17. On May 20, 2009, Pentax announced the lateral chromatic aberration . 18. Newton first demonstrated the presence of chromatic aberration in the human eye in 1670. 19. This version : Substantially edited for chromatic aberration , colour and tonal imbalances and perspective distortion. 20. Simple lenses are prone to aberrations, especially chromatic aberration .
