F8 in a 10 gallon?

Or adding another reflective layer in the mix I.e the plastic, that gives me an idea lol

[scpion]

With the pressure of the water, the bag would have squished flat on my lens. I dun see a clear transparent sheet flat on the lens could reflect anything.. what idea do U have lol.. dun keep us in suspense..!

And yeah, sorry to the OP.. We really hijacked this thread lol!..

Clearly, we need to find one of those children's periscopes that RTR mentioned.

That's incredible! So the chances are they can see their reflection in the tank glass if it's dark!

I love the "sponge birdy" by the way!! lol.

As for kids periscopes, can I venture to suggest some plastic tube and compact mirrors..? Lets go DIY for these experiments!! If I get a proper chance, I'll give it a shot. (Not promising any videos of my head in a fish tank here, just to clarify!)

Possible that the phone's lens isn't the same as an eye's?

Very possible. It captures light differently.

I found zero reflection with all manor of lighting, having my head in a bag and dunking did not work, the bag poked me in the eye, do not try this at home kids.

LOSL - Laughing Out Super Loud!! and its the past midnight here... My gosh.. u really cracked me up... your wife should really snap a photo..

I just dun get it.. I understand looking at the side of the glass will cause a mirror effect with all the refraction/reflection etc.. but if looking at the direct opposite side with my black blackground, I still see a faint mirror... Couldnt find the post that RTR wrote in detail abt this issue.. wanted to do a good read.

??? SMHF- Scratching My Head Off....

We need photographic evidence. Just to be sure.

LOL.. Thats just an excuse to make him go in again so everyone can have a good laugh again, rite?

I agree we need photo evidence. But, I would prefer the shot to be take from the outside by your kind wife.. so, we can see u in the bag, in the tank.. LOL .. sorry.. i just couldnt contain myself!!.... I guess we all didnt think much abt the part where i said " the pressure of the water squished the bag flat on my lens.. "

The bag in eye was super uncomfortable, won't be doing that again. Will be carrying out further lighting and background experiments soon. Will provide photographs of me getting my findings. Ah maybe if I wear goggles in the bag it might work, hmm I have a few new ideas.

[kcartwright856]

Yes, googles! And while your wife has the camera in one hand, perhaps she can have a lamp in the other to mimic different light angles.

seriously, i was almost rotfl at this XD

[bertie 83]

I used torches for lighting up at different angle did not want to hold anything mains powered as I am a little clumsy with electrics. It was my birthday yesterday so am still a little too drunk to experiment today lol. However have a few friends coming round later might see if they fancy a little experimentation

First surface reflections are not mirrors, they do not appear against a silvery background. First surface reflections are common as dirt. Try looking out a window or at picture mounted behind glass. You see yourself or the scene/print behind the glass selectively by focus. The reflected image is transparent, while the image behind the glass is not, even if it is of yourself by silvering the second surface of the glass as with a mirror. Those first-surface reflections are not mirrored. If fish see a first surface reflection, it is not sharp and clear enough to have them react "emotionally" - try that with a betta or male Cichlid. Both ignore the first surface reflections, but react strongly if a real mirror is held against a tank side (or face). Fish do understand water surface refraction and some can easily compensate for it. Some even have modified eyes for eyes in air and water both - Anableps sp. do that, as do others with water-spitting techniques for airborne insects on which they feed. But they do not seem able to grasp the concept of transparent/clear barriers in the water itself. They may learn to avoid it, but that they do "forget" easily - when frightened for example.

True first-surface mirrors are rare in everyday life, as they are so easily damaged. They are common in certain light reflectors and astronomical telescopes, and in mirages.
