    Anyone have a link to an article or video that shows how to setup a white background with proper lightning to create the various effects you see at the high end aquascaping contests? I really want something with lots of pictures and details.

    Thanks, I had read the ASW post already but I'm not a huge fan of those except for the last set.


    With your setup how much space is between the acrylic and the LED? This is what I was looking to get pictures of....that actual setup. My worry is that my current tank position there is only ~12inches behind it and it's a 6ft long tank. I'm worried the light won't diffuse evenly into the acrylic over that entire space and the only way to get it to would be to add more light and make it too bright.

    That tank was only 60cm and the 50cm led was hanging from the kessil brackets almost touching the back of the tank but facing down and not towards to back, I'm using the same method now on my 120cm but need a longer light fitting to give me the same effect as the 60cm.


    A lot of the effect comes from the camera settings, with that photo the room was pitch black with only the tank lighting on


    The tank with lights on but back light off

    The tank with back light on

    And the new tank with the same light shows I need a longer light to get the same effect


    [​IMG]


    I'll get a updated photo of this tank now I have a ati setup and when I get around to getting a longer light.


    I'm not a pro photographer with all the fancy camera lighting that pros like Stu worrall has, so I'm sure that with camera flashes etc it's possible to get even better results.


    The first photo in the second post was taken with my canon 70d the other photos are taken with my Samsung phone and or my sony rx100 compact.


    I'm also interested to hear others feedback and tips on Aquarium photography.

    Do they have backing you can put on the back or is this mainly achieved by backlighting?

    What are you using as the white background and is the back light on the top pointing down or the bottom pointing up?Some pics of the set up from behind the tank may help to see what you have going on there. ( on the smaller tank)


    Thanks.

    That tank no longer exists and I'm not moving the big one :) I will try and get some shots from above if possible, some shots are available on my journal thread.


    A quicker way is to use frosted window film that's removable, Oliver Knott shows an example at the green machine.

    In his first post he said he uses opal acrylic


    Thanks Jason for the pictures and information. It tells me what I wanted to know. I'll probably head to get the acrylic this afternoon.

    The frosted window film is much cheaper but can bubble if not done correctly


    I had some on for a few months and it looked great but started peeling after that and started to look messy, it may of been my fault or heat from the lights? Anyway I change to the acrylic and it lasted until I took the tank down.

    This is a quick photo to try and show how I have it setup..


    It's a bar with a led strip attached facing down and not directly at the acrylic


    ygOiUMv.jpg


    The bar is just resting on my overflows


    You can see the tank then acrylic then the led bar..

    Jason How did you attached it? I was thinking of just using duct tape since it can't be seen anyways...


    I finally found a piece large enough in the drops at a metal distributor. 72" long in white is not a common thing places stock. I got a great deal though...96" x 18" for $8

    That really cheap mine cost me £30 UK lol nice find!


    I attached it with small amount of silicone in each corner and middles so its not noticeable when the lights on.


    As mine is drilled to match my overflows and returns I also put a small seal of silcone around the holes to prevent a leak.

    This is irrelevant if your using a overflow box?

    I should also mention if you are good with fine line silicone place a small strip all the way along the top edge to prevent any excess water running in between the tank and acrylic :) or tape if its hidden I.e hood or in wall etc

    Thanks, My tank is rimmed so I have a ledge on top and bottom to work with. My only worry with the tape is it getting wet over time and possibly creating a slight shadow on the top where it masks the acrylic.

    Do you happen to know the % light transmission of that acrylic sheet you used? I'm looking at some in the ~50% neighborhood but am concerned that might be too translucent. I know Opal30 has 70% transmission vs Opal50, others get as low as 20%. Just trying to decide which to get. My background already has the stick-on frosting, but this seems much cleaner. Also, I have some wires in the back that show through, and a heavier acrylic sheet (that still transmits light) seems like a much more elegant option to hide some of that.

    This is the sticker on the sheet I bought...looks like 32% from the website.


    I'll post some pictures once I'm done so people can see what that percent looks like at least.

    Ah, that would be great. Funny enough, I'm looking at that exact same kind in the WT031, which is 55%. Will be interesting.

    Ah... so 70% light transmission? That's promising then, if it's still that opaque. Of course, 5mm is pretty darn thick... I'm looking at sheets in 1/8" etc. which is close to half that. Thanks for all the info! Going to start browsing
