Haha nanny ye. Chaaittt Overheating adalah keadaan dimana mekanisme pengurusan haba tidak dapat menampung pelepasan haba dengan sempurna akibat 'build-up' haba selepas penggunaan oleh mekanisma pancaran dan bulb. Jadi, secara konsepnya, overheat tak ada kena mengena dengan jenis AA yang digunakan.

Phewww ...

average 4 or 5 pict every mins??? stop la dlm 5 min borak2, isap rokok skit.... but still gettin hot too easy...

last time i did some shoot with my frenz. he using SB600, same shoot taken with me even discuss a bit. still my flash getting hot... i thnk i have some gap for every session and discussing with him... for 1 session will last about 30mins longest...

Sorry....sorry... i din meant the strobist style.
what i meant was the stroboscopic thing. the one where u set the mode to RPT and the flash fires a few times in a single exposure for some special effects like for sports or smth like dat.

this one sure menyebabkan sb900 terbakar lorr

alamak skali send, taleyh.... byk kali tekan, byk plak deir kua..

so we can call 'heat-buffer' la?

Sebenarnya ada jenis jenis bateri yang DITEGAH dari digunakan sebab material bateri tu yang cepat bagi panas. Tapi panas tu bukanlah pada mekanisma pancaran/bulb, tapi pada body atau kompartmen bateri. Dan lagi, ada jenis bateri tu ditegah dari digunakan sebab kapasiti dia. Tak semestinya lagi tinggi kuasa bateri tu, lagi bess ianya digunakan. Ini ada kena mengena dengan circuit yang mana ceritanya aaaaamat lah panjang dan agak mentingtongkan.

Selalnya dalam pengurusan haba, yang ideal nya ialah "jangan pakai buffer, kasik release terus itu haba". So in the case of flashes, theres no heat buffer. Heat-gate aje yang ada.

ada orang kasi mod sb900 letak heatsink kah?

what do u mean heat buffer and heat gate??? already tingtong hahaha

now using energizer 1750 mAh... is it ok?

Hahaha adaaaaa... Gigabyte/Asus ada buat hydro-based heatsink 16valve untuk SB900!! Siap dengan liquid nitrogen tu!




















kidding!!!

Added on September 9, 2009, 12:29 amHeat buffer tu tempat pengumpulan haba untuk diuruskan keluar. Heat gate tu konsep yg digunakan untuk bagi warning kat system flash tu bahawa jumlah haba adalah X-j or Y-kiloJ dan supaya flash to buat keputusan untuk off kan diri dia atau tak.

Ok je Energizer tu. Tapi Energizer body dia cepat jugak panas (bak kata sorang lagi tranny kawan saya kat KL ari tu! tak tau la ye ke tak.)

takleyh ke pasang kipas dkt flash~? cpt skit sejok~! :lol:lol

aku rs ye kot... sbb energizer ble nk kuarkan batteri pas gune, terase panas skit laa

bagus idea ni.. kang kipas tu boleh tala pada photographer..

Hahaha kalau berani dan tak kisah dipandang senget dan serong Saya bawak je kipas. Tapi untuk kipas diri sendiri je le.




Just wanna add ...

Situation A
=======
Exposure Setting A, SB900@TTL - outdoor under the sun

Situation B
=======
Exposure Setting A, SB900@TTL - indoor in dim light

You might be able to burst or shoot continuously with little rest in situation A and not getting overheat at all, but you might get overheat quickly in situation B despite the same exposure setting. Its the flash output.

is it because the flash need to work harder in order to fill the poor lighting condition in situation B?

in A he fire maybe 1/10 adi enough but in B he might need to fire 1/2 to be bright enough and light up the whole scene.

There you go Good answer! Hehe.
So its all about how much power per output the flash uses that results in heat emition and ultimately calls for heat management and bla bla bla .. Not to mention, if you shoot in north pole or sahara
So one shooters flash might overheats faster then the other shooter's depending on what, where and how they strobe.

in north pole...battery also die before can overheat la
hahaha

hah...D90 is weather seal?? later wan shoot at north pole aso cant...LOLX...

shutter mechanism frosted with ice flakes

Haishh .... just an illustration of how environmental factor ie: temperature affects how heat works and managed.
And its flash lah sayang, bukan kameranya. Yang tingtong sangat bawak D90 pergi kutub tu apasal

maybe wanna poison the D90 to those fellow polar bears
