1 Zoom in

Browse to our sup­plied start file, dis­tor­tion_s­tart. NEF. To iden­tify prob­lem colour fringes more clearly, se­lect the Zoom tool from the View Tool sec­tion of the tool­bar. Click to zoom in on the build­ing’s sign. You can clearly see green and pur­ple fringes cling­ing to the edges of the let­ters.

2 Cor­rect Lat­eral aber­ra­tion

Chro­matic aber­ra­tion oc­curs when vary­ing wave­lengths of light aren’t fo­cused on the same part of the sen­sor. Lat­eral aber­ra­tion is more no­tice­able at the edges of the frame. A click on the Lat­eral Color Aber­ra­tion box is all it takes to ban­ish this type of fring­ing.

3 Cor­rect Ax­ial aber­ra­tion

Ax­ial (or lon­gi­tu­di­nal) aber­ra­tion refers to the ap­pear­ance of blurred colours caused by a lens’s in­abil­ity to fo­cus on the same fo­cal plane. A slider en­ables you to fine-tune the cor­rec­tion. There’s no no­tice­able ax­ial aber­ra­tion in this shot so we can leave that box unticked.
