He āhuatanga kore e taea te karo i ngā hapa i roto i te tukanga whakaahua ongā karaihe whatuKo ngā hapa noa ko te hapa chromatic, te hapa porowhita, te astigmatism, te piko o te mara, me te whakapōturi.
He rerekē rawa ngā momo hapa e kitea nuitia ana i runga i ngā āhuatanga mārama, te kaupapa, me ngā whakaritenga tito o ngā horopaki whakaahua rerekē. Mā te mārama me te ako me pēhea te karo i ngā hapa i roto i ngā horopaki rerekē ka tino whakapai ake i te kounga o te ahua.
Kei raro nei, ka tirohia e mātou ngā otinga mō te karo i ngā hapa kua whakaritea i runga i ngā āhuatanga pupuhi rerekē me ō rātou whakaritenga motuhake:
1.Whakaahua whakaahua
Ko te whakaahua āhua he mea e kitea ana i roto i te kaupapa mārama, i te papamuri pōuriuri, me ngā āhua tūturu o te tinana. Tērā pea he mārama, he hangai rānei te rama e whakamahia ana. Ko ngā momo rerekētanga noa ko te rerekētanga porowhita, te koma, te whakapōturi, me te rerekētanga tae.
Ko te whakaahua āhua he mea nui te whakatuwheratanga kia puta ai he bokeh, engari he tino take anō hoki tēnei o te he o te tirohanga porowhita. Mēnā he arotahi whānui te whakamahi, mā te aukati i te 1-2 aukati, pērā i te huri mai i te F2.8 ki te F4, ka pai ake te he o te tirohanga porowhita me te piko o te mara.
Kaua e whakamahi i ngā karāhe whānui rawa mō ngā whakaahua tata, ngā whakaahua tinana-haurua rānei. Mēnā kei te whakamahi koe i te karāhe whānui mō ngā whakaahua tinana-katoa, ngana kia pokapū te kaupapa (ina koa ko ngā kanohi) ki roto i te anga, kia matara atu i ngā taha.
Hei tāpiritanga, he mea nui kia kaua e anga tika te makawe, ngā kamo rānei o te tangata ki tētahi pūtake mārama kaha. Mā te māramatanga kaha o te rama ka whakanui ake i te rerekētanga tae poutū me te astigmatism.
Ka taea e koe te whakamahi i te whakamārama taha me te rama whakakī hei whakaiti i te rerekētanga i waenga i te kaupapa me te papamuri. Mena he pūtake rama ira kei te papamuri, kaua e waiho ki te taha tonu o te ahua hei whakaiti i te pānga o te koma.
Ngā otinga mō te karo i ngā hapa i roto i te whakaahua poutū
2.Whakaahua whenua
Ko te whakaahua whenua e tohuhia ana e tōna tirohanga whānui, te hiahia kia mārama katoa te ahua, he maha ngā tirohanga rerekē teitei, me te mārama taiao (he mārama kaha i te awatea, he mārama ngoikore i te pō). Ko ngā hapa noa ko te whakapōturi, te piko o te mara, te hapa chromatic, te hapa porowhita, me te coma.
Mō te whakaahua whenua i te awatea, mā te whakaiti i te pūwāhi ki te F8-F11 ka whakaiti i te rerekētanga porowhita, te rerekētanga tae, me te piko o te mara, kia tika ai te koi o te ahua. Kaua e whakamahi i te pūwāhi mōrahi, i ngā pūwāhi iti rawa rānei, pērā i te F16 me raro iho, nā te mea ka puta he diffraction, ka whakaiti i te koi, ā, ka puta he whakaahua pōuri me ngā rerekētanga.
I te wā e hopu ana i te hoahoanga me te ultra-arotahi whānui, kia matua arotahi ki ngā karāhe arotahi pūmau koki-tino whānui kia tika ai ngā rārangi hanga me ngā taha whakaahua koi. I te tito, whakatakotoria ngā rohe rerekētanga teitei (pērā i te pae tawhiti, i ngā rārangi maunga rānei) ki waenganui o runga, o raro rānei o te anga, kia matara atu i ngā taha tino tawhiti, hei whakaiti i te rerekētanga tae o te taha. Mā te whakamahi i te taupoki karāhe ka ārai i te mārama kaha mai i te pā tika ki te karāhe, ka whakaiti i te mura me te whakanui i te rerekētanga.
I te wā e tango pikitia ana i te rangi pō, me whakamahi i tētahi karāhe matua whānui-rahi hei whakahaere pai ake i ngā hapa o ngā whetū; kaua e whakamahi i te karāhe whakanui mōrahi hei tango pikitia i te rangi pō, nā te mea ka kitea nuitia te koma.
Mā te arotahi ki te mutunga kore, me te whakanoho i ngā whetū ki waenganui o te anga ka taea te whakaiti i te hekenga o te whetū e puta mai ana i te koma. Mena ka puta he tapa tae ki runga i ngā whetū, whakahohea te whakatikatika i te chromatic aberration i roto i te kāmera hei pehi i te chromatic aberration i mua.
Mā te whakamahi i te tūru me te taura tuku i te wā e hopu ana i te whakaahua ka ārai i te pōuriuri i puta mai i te rūrū me ngā hapa o te kāmera. Whakawetohia te whakaiti haruru o te whakaaturanga roa o tō kāmera, nā te mea ka taea e te whakaiti haruru o ētahi tauira te whakawhāiti i ngā taipitopito me te whakanui ake i ngā hapa; ka taea te whakamahi i te whakaiti haruru pūmanawa i te tukatuka muri.
Ngā otinga mō te karo i ngā hapa i roto i te whakaahua whenua
3.Whakaahua makro
Ko te whakaahua makro he āhuatanga pumau, he rama ka taea te whakahaere, me te whai i te māramatanga tino pai o te ahua. Heoi, ko ngā hapa e ngāwari ana te puta, pērā i te hapa porowhita, te piko o te mara, te astigmatism, me te hapa chromatic, ka whakanuia i raro i ngā āhuatanga makro.
Mō te whakaahua makaro, e taunakihia ana kia whakamahia he karāhe makaro motuhake, kua arotauhia mō te whakaahua tata, ā, ka whakatika i te piko o te mara me te astigmatism. Ki te whakatauritea ki te whakamahi i ngā karāhe whakamārama, whakanui rānei mō te whakanui,ngā arotahi makroka tino whakaiti i te whakapohehetanga me te he o te tae.
I taua wā, ko te whakaahua makaro he tino pāpaku te hohonutanga o te mara, e hiahiatia ana he kōhao iti ake hei whiwhi i te koi e tika ana, ā, ka āwhina hoki ki te whakaiti i ngā hapa. Heoi, me aro ki ngā pānga o te diffraction, e hiahia ana pea ki te hanga i te hohonutanga o te mara. E taunakihia ana kia whakaritea ngā karāhe makaro me ngā āhuatanga apochromatic hei pehi i te hapa chromatic mai i te tirohanga whatu.
Hei tāpiritanga, mā te whakamahi i te rama ngawari ka taea te whakaiti i te rerekētanga tae o ngā taha teitei-whakamārama o te kaupapa; i te wā e arotahi ana, tīpakohia te pokapū o te ahua, ā, whakanohoia te kaupapa matua o te whakaahua ora tonu ki waenganui o te ahua kia taea ai te whakaiti i te pānga o te hapa taha; mō te ora tonu whakatakotoranga nui, ka taea e koe te whakamahi i te arotahi rohe hei utu mō te pōuri o te taha i puta mai i te piko o te mara.
Ngā otinga mō te karo i ngā hapa i roto i te whakaahua makaro
4.Ngā mahi hoahoa meirotopwhakaahua wera
Ko te whakaahua whare he āhuatanga e whai ana i ngā rārangi whare tika, ngā ōwehenga tika, me ngā taipitopito mārama puta noa i te ahua. Tērā pea he mārama tūturu, he mārama horihori rānei te rama, ā, he ngāwari ki te pāngia e ngā hapa pērā i te whakapōturi, te piko o te mara, te rerekētanga tae, me te astigmatism.
Ko ngā karāhe hurihuri-whakatītaha te mea pai mō te whakaahua whare. Ka taea e rātou te whakatika katoa i te hē o te tirohanga me te hē o te pūwero/urunga titi mā te neke, te whakatītaha rānei i te tuaka whatu, me te whakakore i te piko o te mara, me te whakarite kia ōrite te koi o te pokapū me ngā taha o te ahua, kia kore ai e hē te pūtake mai i te tirohanga whatu.
Mā te whakamahi i te ultra-arotahi whānuika taea te hopu i te wāhi, engari he ngāwari ki te whakapōturi i te oko. Ina tangohia he karu whānui, me whakaiti te whakatuwheratanga ki te F8-F11 hei pehi i te piko o te mara me te he o te tae.
Ina tangohia ngā whakaahua whare mai i raro, i runga rānei, ngana kia rite te kāmera ki ngā rārangi whare hei whakaiti i te hē o te tirohanga. Ki te kore e taea te pupuri i te taumata o te kāmera, ka taea te whakamahi i ngā taputapu whakatika tirohanga i te tukatuka muri.
I te tito whakaahua hoahoanga, me whakarite kia whakarara ngā rārangi matua o te whare (pērā i ngā pakitara me ngā anga matapihi) ki te rohe o te anga kia kore ai e puta he rārangi i te taha tonu o te ahua.
Whakamahia te rama mārie mō ngā whakaahua whare o roto hei whakaiti i te āhua o te kanohi e puta mai ana i te iti o te mārama, me te whakaiti anō hoki i te rerekētanga teitei o te karāhe/whakarewa, me te pehi i te rerekētanga tae. Mō ngā whakaahua whare o waho, tāutahia he taupoki arotahi hei karo i te kanapa me te whakanui i te rerekētanga e puta mai ana i te mārama kaha e whiti tika ana ki roto i te arotahi.
Ngā otinga mō te karo i ngā hapa i roto i te whakaahua hoahoanga me te whakaahua o roto
5.Ngā kararehe mohoao me ngāsngā taurangapwhakaahua wera
Ko ngā whakaahua kararehe mohoao me ngā hākinakina e whakamahi ana i ngā karāhe whakaata-rahi. Ko ngā tirohanga e tohuhia ana e te nekehanga tere o te kaupapa, e hiahia ana kia tere te aro turuki i te arotahi, ā, ka kaha, ka ngoikore rānei te rama. Ko ngā raruraru aberration noa ko te coma, te astigmatism, te chromatic aberration, me te spherical aberration.
I te wā e kiriata ana i ngā kararehe mohoao/hākinakina, me whakarite kia rite ki ngā mea nuingā arotahi whakaahua-rahime ngā huānga iti-marara hei pehi pai i te rerekētanga tae. I roto i te mārama kaha o waho, mā te aukati i te whakatuwheratanga mā te 1-2 aukati, hei tauira, mai i te F2.8 ki te F4, ka taea te whakapai ake i te koi o te pokapū me ngā taha, te pehi i te koma me te astigmatism, me te whakapai ake i te tika o te arotahi aunoa.
Ina tangohia ngā mahi hākinakina i te iti o te mārama, ā, me nui te whakatuwheratanga, whiriwhiria te tuarua o ngā whakatuwheratanga nui rawa atu o te arotahi (pēnei i te F2.8). Mēnā ka puta he koma, kati ki te F3.5 hei whakataurite i te mana o te urunga mārama me te mana whakahaere i te he. Mā te whakahohe i te aratau aroturuki arotahi tere-teitei o te kāmera ka noho tonu te arotahi ki te kaupapa e neke ana, ka whakaitihia te pōuri o te he i puta mai i ngā take kore-arotahi.
Hei tāpiritanga, mā te whakamahi i tētahi pupuri arotahi waea + tūāpapa/monopod ka taea te whakaiti i te rūrū o te arotahi me te karo i te astigmatism e puta mai ana i te rūrū; mā te tāuta i tētahi taupoki arotahi ka taea te ārai i te pānga o te rā tika ki te arotahi i te wā e tango whakaahua ana i waho, ka whakaiti i te kanapa me ngā aberations; i te wā e tango whakaahua ana i ngā manu e rere ana/e tere ana te neke, ngana ki te whakakī i te pokapū o te anga ki te kaupapa hei whakaiti i te pānga o ngā aberations taha.
Hei whakamutunga, hei karo i ngā raruraru o te he o te arotahi, me mārama tuatahi koe ki te arotahi e whakamahia ana e koe. He whānuitanga mahi tino pai tō ia arotahi. Whakamātauria tō arotahi i mua i te wā hei whakatau i te roa arotahi, te whakatuwheratanga rānei e tino kitea ana ngā he, ā, karohia rawatia i te wā e tangohia ana te whakaahua.
He mea nui kia mōhiotia ko te whakatikatika whatu o ngā hapa (te kōwhiringa arotahi, te aukati i te kōhao, te whakatikatika i te tuaka whatu) he mea nui, ko te whakatikatika tukatuka-muri he mea tāpiri noa iho; mā te tukatuka-muri nui rawa ka ngaro te taipitopito o te ahua.
