55 gallon pic

haha, no rags. i'm a paper towel freak myself. and by the way, no fish has jumped out, yet (where's wood when you need it to knock on?).

thanks for the comments on the pics, i've previously shared them on the general freshwater forum, don't want to overdo it. and joe, that reflection on the tank comment is hilarious. i'm sure it wasn't you. :p

A separate flash is useful in taking pictures of fish, but not absolutely necessary in over all tank pics. I recommend turning off the flash, setting the f stop to 2.5, and shutter speed to 1/20-1/40. That can get you some decent pics.

Actually, no. I mean, you CAN take a photograph that way, but the results won't be so pleasing.
With f 2.8 and speed of 1/15 or 1/30 all you can get is blurry or ghost fish, very narrow depth of field and if not using correction filters, too orange or too blue light.
Also these values depend on ISO film speed, they are not definite.

Flash is essential, but you have to know how to operate it and where to put it. Of course, I'm talking about removable flash units, not cameras built-ins. Flash duration is usually 1/8000 or 1/10000, so that can instantly freeze even the fastest fish and DOF is usually f11 or f16 even with ISO 100.

Nope not me...
I think it was an honest mistake. I don't think he ever posted again, or at least changed his name here.. LOL
 
As i mentioned in my first post, I agree that flash is quite necessary in taking pics of fish. However, that is often not the primary goal in tank pics, and few people are willing to pay for a separate flash for the sole purpose of fish pix. A neon might move, quickly, but an amazon sword plant is less likely to do so. Instead, people are often after a decent over all tank pic which show the gestalt of their tank. I admit im not a photo hobbyist, or know all that much about taking pix, but the specs i quoted have gotten me good results for over all tank pics, as well as some close ups. The lack of a flash forces the low f stop and long exposure time.

Also, these are for digital pictures, I specifically use an olympus C3020Z

Then, if plants and slow moving objects is all you want,
if the metered value is e.g. f2.8 1/30, it's better to set f5.6 1/8, f8 1/4 or slower, in order to have greater depth of field.

The specs depend on the available light and ISO film/digi speed. Even the slight light variation can change the settings.
In your case, you either had an auto-metering done by the camera or luck to do so. :)

In order to fully understand digital, you must first learn standard photography. There's no difference between the standard and digital metering (digital works like slides).

Good luck in your photo sessions. :)
