In principiu exista blitz-urile cu declansare prin comanda optica. Cu ajutorul unui cablu din fibra optica se preia semnal de la blitz-ul compactei (direct prin plasticul carcasei) si se declanseaza blitz-ul extern. Singura modificare (home made) ar fi ca trebuie, 1 sa fixezi acel cablu + suport blitz pe carcasa si 2 sa opturezi restul de lumina degajata de blitz-ul compactei. Toate acestea, bineinteles, pentru carcasele care nu sunt prevazute cu optiune de flash extern. Carcasa mea pentru canon A610 nu are aceasta optiune.

interesante posturi...
am facut si eu foto sub apa cu un aparat canon720 cu carcasa UWater
ar fi interesant de vorbit despre ce inseamna sa faci poze sau film sub apa...in ce fel aceasta activitate poate stanjeni scufundarea sau nu :p
...they say scuba-divers go into the deep to look arround...and the free-divers to look into themselves...

Eu personal, la o tura de fotografiere subacvatica, consum mai mult aer decat de obicei! Si mi se pare mult mai obositor!....Sa cauti subiectii....sa te pozitionez cat mai favorabil....

Eu am un flash extern de la un SEALIFE care poate fi atasat in principiu (l-am vazut defapt pus la un CANON al unui prieten) la orice alta carcasa uw cu niste accesorii pe care le gasesti la cei care vand acest flash.

Daca tot se invart pe aici avioane un loc de aparate foto, am si eu o intrebare:
Stie cineva o carcasa u/w pentru obiectivul din imagine? Ma gandeam sa fotografiez rechini de la o distanta sigura. :lol: :lol: :lol:

Scuze de Off topic dar de-a lungul posturilor sunt prea putine informatii de gen "tips & tricks" si prea multe "avioane" si "copy/paste". Chiar si initiatorul topicului nu a venit decat cu un link catre un manual, manuale care in general pornesc de la origini cu chestii foarte stufoase si tehnice (inclusiv refractie, mecanica, electronica), in principiu abordand profesionistii cu ale lor DSLR-uri u/w. Sunt foarte interesat de reale informatii ce ar fi de folos amatorilor (recte eu) posesori de "sapuniere".
Ceva de genul: La achizitionarea unui aparat destinat fotografiilor subacvatice trebuie urmarit in special cutare aspect! sau Atentie nu fortati ISO peste x % din valoarea maxima a aparatului pentru ca .... sau Am observat ca la aparatele X folosirea unu F peste cutare valoare scade drastic calitatea fotografiei.
Deci ... sa vedem cine intreaba/raspunde on topic :roll:

>papie - am inteles ironia cu teleobiectivul, si nu neaparat la post-ul tau se referea remarca mea.
>ceilalti utilizatori - la fel cum iarna nu-i ca vara, forumul nu-i ca fereastra de messenger in care sa aruncati gramada toate linkurile la care v-ati excitat. (cu exceptia celor care chiar aduc informatii interesante sau utile).

ON TOPIC:
Parerea mea este ca sub apa diafragma trebuie tinuta deschisa la maxim, atat timp cat nu aveti blitz-uri externe. Profunzimea de camp va avea putin de suferit, dar prefer un timp mai scurt de expunere si o poza mai clara decat o poza miscata, da' cu profunzime de camp.
In fine, daca esti aproape de suprafata, apa e limpede si soarele straluceste la amiaza, poti sa inchizi diafragma linistit, fara grija timpului de expunere prea lung.

Eu cred ca e mai bine pentru comunitate sa fim mai relaxati in privinta regulilor de pe forum. Daca vom fi prea stricti, atunci lumea nu va mai posta de teama sa nu fie offtopic si usor-usor va deveni pustiu (vezi celelalte forum-uri care aproape au disparut: Delphi, Carpatica, etc).

Personal intru pe forum ca sa aflu lucruri noi, rar imi pasa daca un raspuns este sau nu ontopic (nici cele offtopic nu sunt total offtopic).

------------------------------------------

Multe obiective (fie ele standalone sau built-in) nu se comporta prea bine (sharpness, etc) la extreme si nu e recomandat sa le folosesti nici la apertura minima, nici la cea maxima. Creste apertura cu un F-stop si ar trebui sa obtii imagini mai bune.

De obicei problemele acestea sunt usor de remarcat in review-urile de pe photo.net sau dpreview, asa ca va recomand sa cititi acolo, sau chiar sa faceti teste cu propriul aparat pe uscat si mai apoi in apa.
