Recently, i fall in love with fish, and taken several aquarium photograph. So, i would like to share some of my experience and what i had learned. The first thing i learn, is never NATO (no action talk only). I have found that, a lot of person will talk about CPL filter (kind of filter to reduce reflection of glasses) when they heard about aquarium photograph. Theoretically, aquarium will have reflection and CPL filter is needed. But, this is only theoretically, the fact is, not necessary. First of all, to avoid reflection of glasses, we just need to understand why there is a reflection. Simple reason, reflection occur when inner lighting is lower than outer. Same reason apply to building glasses and window, why we can't see through the window at day time, but can see through at night. Hence to avoid reflection, we just make the inner lighting higher than outer, just simple as that, we don't need CPL filter at all. We can switch off the lamp to lower down the environment light (outer), or increase the flash light power which the flash light is remove controlled, and place at the top of aquarium(inner). Build in flash is not able to reduce reflection.
01. If the inner lighting is lower, reflection will occur.
The next is about technical part. When taking aquarium photograph, try ur best to make ur object far from the aquarium glass which is close to ur camera, because we don expect the aquarium is crystal clear. If ur object is too close to the glass which is close to ur camera, u might capture some dust or scratch on the glass. (Refer to photo below)
02. Fingerprints on glass... =.=
Secondly, try to place ur camera 90degree to the glass. If ur camera is not 90degree to the glass, refraction will occur (refer to photo below). Hence ur image might be distorted, and ur camera might not able to focus well, or out of focus.
03. Refraction occur.
Lastly, apply what u have learn, heard, or read. Never NATO. Trust me, u will know more than what u known =)
