Pai rawa atu mō te whakaahua i raro i te wai: Kāmera Mamati
He tino ātaahua te whakaahua i raro i te wai, he uaua ki te whakataurite. Ko te ao e huna ana i raro i te mata he mea ahurei ngā tae, ngā kakano, me ngā whanonga o ngā mea ora—mai i ngā taipitopito whai kiko o ngā toka korara ki ngā wā poto o ngā ika e kaukau ana i waenga i ngā toka. Heoi, ehara i te mea ko te maia ki te ruku noa te mahi whakaahua i raro i te wai. Me whai kāmera matihiko tika, he tiaki tika, me te māramatanga taketake ki te māramatanga me te tae. Ka matapakihia e tēnei tuhinga te whiriwhiri i te kāmera matihiko pai rawa atu mō te whakaahua i raro i te wai, ngā āhuatanga hei whakatau i ngā mea nui, me ngā kāwai kāmera e taunakitia ana i runga i ō hiahia.
He aha te hiranga o tētahi kāmera motuhake mō raro i te wai?
He uaua te wai mō ngā kāmera. Tuatahi, ka tere te mimiti i te mārama me te tae, inā koa ngā whero me ngā kōwhai. Ka hohonu ake tō ruku, ka nui ake te tūponotanga ka puta he kikorangi, he kakariki rānei ō whakaahua. Tuarua, ka taea e ngā matūriki iti i roto i te wai te whakaputa i te hoki whakamuri, arā, ko ngā ira mā e puta mai ana ina pā te uira ki ngā matūriki i mua i te arotahi. Tuatoru, ka piki ake te pēhanga wai i te hohonutanga, me whai tinana ārai wai, he whare piripono, he whare pakari hoki.
Nō reira, ko te mea pai ko te kāmera matihiko raro wai kia ātete wai, kia hototahi rānei ki tētahi whare kounga teitei. Hei tāpiri, ko te arotahi aunoa tere, te mahi ISO pakari, me te tautoko rama tāpiri ka pā nui ki te hua whakamutunga.
Ngā Ara Matua e Rua: Ngā Kāmera Ārai Wai me ngā Kāmera Whai Whare
I te nuinga o te wā, e rua ngā kōwhiringa nui:
1. Kāmera pakari/mārō (ātete wai)
Ka taea te whakamahi tika i tēnei momo kāmera mō te ruku wai, te ruku pāpaku rānei, me te kore he whare tāpiri. He whai hua, he māmā, ā, he tino pai mō ngā hararei. Ko te ngoikoretanga he iti ake te pūoko i te kāmera kore whakaata/DSLR, e whakawhāiti ana i te kounga o te ahua me te ngāwari o te arotahi.
2. Kāmera Kore-whakaata/DSLR i roto i te whare
Kei roto i tēnei kōwhiringa ngā āhuatanga pai rawa atu: he pūoko nui, he mana ā-ringa katoa, me te whānuitanga o ngā karāhe whānui me ngā karāhe makaro. Heoi, he nui ake te utu me te uaua o tēnei karāhe nā te mea e hiahiatia ana he whare, he putanga karāhe, me ngā taputapu pēnei i ngā paepae, ngā ringaringa, me ngā rama.
Ko te whiriwhiri i te ara tika e whakawhirinaki ana ki ō whāinga: te tuhi tuhinga noa, te whakaahua nui rānei me ngā paerewa ngaio.
Ngā Āhuatanga Matua o te Kāmera Mamati mō te Whakaahua i raro i te Wai
I mua i te whiriwhiri i tētahi waitohu, i tētahi tauira rānei, kia aro ki ngā āhuatanga e whai ake nei:
1) Ātete Wai me te Hōhonutanga Mōrahi
Ki te whiriwhiri koe i tētahi kāmera ātete wai, tirohia te hohonutanga (hei tauira, 10 m, 15 m, neke atu rānei). Mō te ruku wai, ko ngā hohonutanga o te 30 m, neke atu rānei, me whai wāhi motuhake, kaua ko tētahi kāmera pakari anake.
2) Rahi o te Pūoko me te Kounga Whakaahua
Ko te tikanga, he iti ake te haruru me te pai ake o te whānuitanga hihiri o ngā pūoko nui. I raro i te wai, he maha ngā wā ka ngoikore ake ngā āhuatanga rama—mā te pūoko kounga teitei ka āwhina i te pupuri i ngā taipitopito me te tae.
3) Te Āheinga RAW
He painga nui te tango whakaahua i te whakatakotoranga RAW. Mā te RAW ka taea te whakatika i te taurite mā, te whakahoki mai i te tae whero, me te whakaiti i te kohu i te wā e whakatika ana. Mō te whakaahua i raro i te wai, he mea nui te RAW mēnā e hiahia ana koe ki ngā hua tino pai.
4) Arotahi Aunoa Tere me te Tika
He tere te neke o ngā ika, he tere tonu te neke o te kaiwhakaahua nā ngā ia, ā, he iti noa te tirohanga i ētahi wā. Mā te kāmera he pai te arotahi aunoa—tae atu ki te aroturuki—ka nui ake te tūponotanga o te hopu whakaahua koi.
5) Te Whakapūmau (OIS/IBIS)
He tino āwhina te whakaū i te āhua ina tangohia he tūrama, inā koa mō te tango ataata, mō te tango whakaahua rānei i te hōhonutanga iti o te mārama.
6) Arotahi (mō te Pūnaha Whakawhiti)
– He pai te koki whānui mō ngā ākau korara, ngā kaipuke pakaru, me ngā whakaahua "koki whānui arotahi-tata" hei tiki i te tirohanga tata o te kaupapa me te papamuri whānui.
– He pai te makro mō ngā manga nudibranch, ngā kōura ririki, ngā kakano korara, me ngā taipitopito moroiti.
Ki te whiriwhiri koe i tētahi kāmera kore whakaata/DSLR, kia tino oti te pūnaha arotahi, ā, kia ngāwari hoki te kimi i te putanga o te kāmera.
Ngā Taunakitanga mō te Kāwai Kāmera Pai rawa atu
Anei ngā taunakitanga e hangai ana ki te kāwai whakamahinga. Kaua e arotahi ki tētahi tauira, engari arotahi ki te momo kāmera e pai ana ki a koe, nā te mea ka rerekē pea te wātea o te hua me ngā tauira hou.
A) Kāmera Ārai Wai Whaihua mō te Ruku me te Hararei
He pai ngā kāmera pakari mō ngā kaiwhakamahi e aro nui ana ki te whakamarie. Ka taea e koe te ruku noa ki roto ka tango whakaahua me te kore e hiahia ki te tāpiri i tētahi whare. He pai mō tēnei kāwai ngā kāmera me:
– te whakatauranga hohonu mārama,
– te aratau raro i te wai e āwhina ana ki te taurite mā,
– te kaha ki te tuhi ataata pumau,
– me te tinana ātete ki te pānga.
He pai tēnei momo kāmera mō te takutai moana, te puna kaukau, te ruku wai rānei. He iti noa iho ngā kōwhiringa mō ngā ruku hohonu me ngā hihi o waho.
B) Te Moni Whakakī me te Whare Noho mō te Kounga Tino Pai
Ki te hiahia koe ki te kounga pai ake engari kei te hiahia tonu koe ki te rahi kiato, he kōwhiringa ātaahua te pūoko iti kounga teitei me te pūoko nui ake. Mēnā he pai te whare, ka taea e koe:
– te tango whakaahua RAW,
– te whakamahi i ngā rama ataata, i ngā rama rānei,
– ā, kia koi ake ngā hua i te rugged noa.
He "arawhata" pai tēnei wāhanga mō ngā tīmatanga e hiahia ana ki te tīmata ki te whakamahi me te kore e peke tika atu ki tētahi pūnaha kore whakaata.
C) Ngā Whare Kore-Whakaata: Te Kōwhiringa Tino Pai a ngā Kaiwhakaahua o raro i te Wai
He kounga teitei, he tere te arotahi, ā, he iti ake te rahi o ngā kāmera whakaata hou i ngā kāmera DSLR. Ngā painga:
– te pai ake o te mahi i te iti o te mārama,
– ngā kōwhiringa arotahi whānui (whānui me te makaro),
– te arotahi aunoa matatau mō ngā kaupapa e neke ana,
– me te ataata kaha hoki (4K/10-bit i runga i ētahi tauira).
Mō ngā kaiwhakaahua e whai ana i te kounga o ā rātou kohinga whakaahua, he mea tino noa te pūnaha whakaata kore me ngā hihi takirua.
D) Kāmera Mahi mō ngā Ataata me ngā Koki Tino Kaha
He tino pai ngā kāmera mahi i:
– te ataata POV i a koe e ruku ana,
– te tuhi tere i ngā mahi,
– te tāutanga ki runga i te potae, i te taputapu ruku rānei,
– tae atu ki ngā ihirangi pāpāho pāpori.
Heoi, mō te whakaahua tino taipitopito, he iti te pūoko me te arotahi whānui-rahi, ā, kāore i te tino whai hua. Heoi anō, mō te haereere me te tuhi i ngā wheako, he kōwhiringa ngahau, he māmā hoki ngā kāmera mahi.
Ngā Taputapu Hiranga mō ngā Hua Whakaahua Ngaio Ake
Kāore e ranea te kāmera pai anake. He nui te āwhina o ngā taputapu e whai ake nei mō te whakaahua i raro i te wai:
1. Whare Noho i raro i te Wai (mēnā e hiahiatia ana)
Me whakarite kei roto i te pouaka he mowhiti-O ma, he pai te tiaki, e ōrite ana ki te tauira o te kāmera. Ahakoa he iti noa te turuturu ka mate pea.
2. Rama Whero, Rama Ataata rānei
Ka āwhina te rama horihori ki te whakahoki mai i te whero, me te whakarato i te rerekētanga. He pai ake te whai hua o ngā rama mura mō ngā whakaahua, ko ngā rama ataata ia he pai mō te tuhi.
3. Te paepae me te ringa
Āwhina ki te whakau i te kāmera me te whakarerekē i te tūranga o te hihi hei whakaiti i te marara whakamuri.
4. Tātari Whero (ina koa mō ngā ataata)
He whai hua i ētahi hōhonutanga ina tangohia te rama, engari e whakawhirinaki tonu ana ki te wai me te āhua o te mārama.
5. Whakangungu Pupuhi
Ehara tēnei i te taputapu, engari he pūkenga nui. Mā te whakahaere pai i te pōrewarewa ka noho pumau koe, kāore e kino te toka, ā, ka māmā ake te anga.
Tohutohu Tere mō te Pupuhi i raro i te Wai
– Nekehia te kāmera kia tata atu ki te kaupapa hei whakaiti i te kohu me ngā matūriki i waenganui i te arotahi me te mea.
– Whakamahia ngā koki rama (te rama mai i te taha, kaua mai i mua) hei whakaiti i te marara whakamuri.
– Whakatikatikahia te taurite mā, whakamahia rānei te RAW hei whakahaere i te whakatikatika tae.
– Tangohia he maha ngā anga o tētahi kaupapa e neke ana—ka nui ake ō tupono ki te tango i tētahi whakaahua tino tika.
– Kia mau ki ngā tikanga matatika mō te taiao: kaua e pā ki ngā korara, kaua e whaia ngā kararehe, kaua hoki e whakararuraru i ngā nohanga.
Whakamutunga
