A karu āwhataHe arotahi whānui rawa te arotahi, e mōhiotia ana ko te arotahi panoramic. E whakaarohia whānuitia ana ko te arotahi he 16mm te roa arotahi, he poto ake rānei te roa arotahi he arotahi kanohi ika, engari i roto i te hangarau, ko te arotahi he nui ake i te 140 nekehanga te whānuitanga o te koki tirohanga ka kiia he arotahi kanohi ika. I roto i te mahi, tera ano etahi arotahi he koki tirohanga neke atu i te 270 nekehanga, tae atu rānei ki te 270 nekehanga. Ko te arotahi kanohi ika he rōpū mārama anti-telephoto he nui te whakapōturi o te oko. Ko te arotahi o mua o tēnei arotahi he parabolic te putanga ki mua, ā, he rite te āhua ki te kanohi o te ika, nō reira te ingoa "arotahi kanohi ika", ā, he rite tōna pānga tirohanga ki te ika e mātakitaki ana i ngā mea i runga ake i te wai.
Te karu ā-ika
Ka whakawhirinaki te karu tirohanga ika ki te whakauru hangai i te nui o te whakapōturi o te oko hei whiwhi i te koki tirohanga nui. Nō reira, haunga ngā mea kei waenganui o te ahua, ko ētahi atu wāhanga e tika ana kia tika ngā rārangi he whakapōturi, ā, he maha ngā herenga mō tōna whakamahinga. Hei tauira, i roto i te mara o te haumarutanga, ka taea e te karu tirohanga ika te whakakapi i ngā karu tirohanga noa maha hei aroturuki i te whānuitanga whānui. Nā te mea ka taea e te koki tirohanga te eke ki te 180º, neke atu rānei, kāore he koki mate mō te aroturuki. Heoi, nā te whakapōturi o te ahua, he uaua ki te kite i te mea e te kanohi tangata, ka tino whakaiti i te kaha aroturuki; Ko tētahi atu tauira i roto i te mara o te karetao, me kohikohi e ngā karetao aunoa ngā mōhiohio ahua o ngā tirohanga huri noa me te tautuhi i a rātou kia mahi i ngā mahi e rite ana.
Mena hekaru āwhataIna whakamahia, ka taea te whakanui ake i te pai o te kohikohinga mā te 2-4 ngā wā, engari nā te hapa ka uaua te tautuhi i te pūmanawa. Nō reira, me pēhea tātou e kite ai i te ahua mai i te karu fisheye? Kua whakaratohia he raupaparorohiko hei tautuhi i ngā tūranga o ngā mea i roto i te ahua. Engari he uaua hoki te mohio ki ngā whakairoiro uaua nā te uaua o te rorohiko. Nō reira, ko te tikanga noa ināianei ko te whakakore i te hapa o te ahua mā te raupapa o ngā panonitanga, kia whiwhi ai i tētahi ahua noa, kātahi ka tautuhia.
Kāore anō kia whakatikatikaina, kia whakatikatikaina hoki ngā pikitia kanohi ika
Ko te whanaungatanga i waenga i te porowhita ahua me te pūoko koia ēnei:
Te whanaungatanga i waenga i te porowhita ahua me te pūoko
I te tīmatanga,ngā karu kanohi ikai whakamahia noa i roto i te whakaahua nā te mea he āhua motuhake nā te whakapōturi o te oko i te wā e whakaahuahia ana. I ngā tau tata nei, kua whakamahia whānuitia te arotahi kanohi ika i roto i te ao whakaahua whānui, te ope taua, te tirotiro, te whakaata tirohanga whānui, te whakaata porowhita me ētahi atu. Ki te whakatauritea ki ētahi atu arotahi, he iti ngā painga o te arotahi kanohi ika, arā, he mama, he iti hoki te rahi.
