Indlela yokukhetha ummese wokusika we isiceli senyama eqandisiwe

1. Umumo we-flat concave: usetshenziselwa izisiki ezishelelayo noma izisiki zenyama eqandisiwe ezijikelezayo.

2. Umumo we-concave oyisicaba ojulile: usetshenziselwa ukusika i-collodion kuphela, ngoba i-blade incane, i-blade izodlidliza lapho isetshenziselwa ukusika izinto eziqinile neziqinile.

3. Ukuma kwe-concave kabili: Isetshenziselwa ukusika izingcezu zikapharafini ngokunyakazisa isisiki senyama eqandisiwe kanye nesisiki sokushelela.

4. I-Flat wedge: isetshenziselwa ingxenye yepharafini evamile kanye nengxenye yesampula ye-macroscopic.

Izinhlobo ezahlukene zokusika inyama eqandisiwe zinemimese yokusika ehlukene. Singakhetha isisiki ngokwekhwalithi yenyama eqandisiwe, ukuze sisike izingcezu zenyama ezingcono futhi sithuthukise ukusebenza kahle.
