Whakamātautau Piri
Whakamātautau Tapahi Whakawhiti
Tikanga whakamātautau:Tapahia kia 100 ngā tapawhā (1 mm)² ia) mā te whakamahi i te maripi mata, kia kitea ai te papa.
Tāpirihia te rīpene piri 3M610 kia pūmau, kātahi ka haehae wawe i te 60° i muri i te 1 meneti.
Tirohia te piri o te peita ki te mata.
Ngā Paearu Whakaae: Te tangohanga o te peita < 5% (≥whakatauranga 4B).
Taiao:Te pāmahana rūma
Tirotiro Rerekētanga Tae
Rerekētanga Tae (ΔE) me ngā Wāhanga
ΔE = Te rerekētanga tae katoa (rahi).
ΔL = Māramatanga: + (mā ake), − (pōuri ake).
Δa = Whero/Kākāriki: + (whero ake), − (kakariki ake).
Δb = Kōwhai/Kikorangi: + (kōwhai ake), − (kikorangi ake).
Ngā Taumata Manawanui (ΔE)
0–0.25 = Te ōritenga tino pai (tino iti/kāore).
0.25–0.5 = Iti rawa (e whakaaetia ana).
0.5–1.0 = Iti-waenga (e whakaaetia ana i ētahi wā).
1.0–2.0 = Waenga (e whakaaetia ana i ētahi tono).
2.0–4.0 = E kitea ana (e whakaaetia ana i ētahi wā).
>4.0 = Tino nui (kāore e whakaaetia).
