Question on lighting to photograph terrarium
I'm running a webcam to watch my terrarium, but I'm having a heck of a time
with lighting. Presently, I am using ambient room light+blacklight above the terrarium. This results in reflections visible in the glass of the terrarium, meaning you can actually see the reflection of the camera tripod in the picture. I've tried lighting above the tank, but it tends to "flare" at the top. Can anyone give advice in regards to positioning, and relative brightness? -The cam can be viewed at www.mantiscam.com -I am using a fairly high quality webcam - the 3com Homeconnect. -Terrarium is presently humidifying, so ignore the fog for now. -- .................................................. ............................

A trick in photography to reduce reflection is to use hair spray on the
glass which would matt the glass a bit. Shouldn't the terrarium have a daylight neon to aid with the photosynthesis of the plants, lizards, snakes, etc? That way you'll be illuminating the interior, so no need for external lighting. I see you already have the blacklight on, and it is a bit foggy, but the leaves in the foregroung seem quite clear. wrote in message news:ReAnb.64180$zx2.18354@edtnps84...

Shouldn't the terrarium have a daylight neon to aid with the photosynthesis of the plants, lizards, snakes, etc? That way you'll be illuminating the interior, so no need for external lighting. There's no live plants... Praying Mantids, which this cage is build for, don't need live plants, and don't like harsh direct light - Mainly they just need stuff to climb on, and a lot of heat and humidity. Any lights I have added tend to create a "flare" effect at the top of the frame. I see you already have the blacklight on, and it is a bit foggy, but the leaves in the foregroung seem quite clear. Fogging should be done within the hour. Can you see all of the distortions, though, including veritical lines, and the camera tripod? -- .................................................. ............................

I'd tend to agree - daylight wavelengths will help plants grow (and surely be healthier for the inhabitants too) - though obviously couldn't be used at night. Lighting the inside of the tank rather than the outside is the way to get rid of the reflections though - that, or (if you have clear sides) put light in from the front/sides? Velvet |

Failing that, try aiming the light at an angle to the glass, then moving the camera around at an angle also. Try draping black cloth (velvet is very good for this) over the tripod legs so they're not reflective. Velvet |

The suspense is frustrating! Nonetheless, the wait has been good, in that it's given me time to fine-tune the environment, and determine better ways to maintain the appropriate heat/humidity. -- .................................................. ............................

That sounds pretty cool actually. I have an empty tank but I don't feel like getting fish again. I used to have some Hermit Crabs and then a couple of Madagascar Hissing Coackroaches (just like on Fear Factor) |
