Im not necessarily disagreeing with anything, and certainly not negating any of the feedback, but I want to make this a 360 degree endeavor so here are some further discussion points. I agree that the fantail guppy is overexposed. I had almost resolved myself to having to fix that in post. Believe it or not, beyond the guppy, the lighting on the fish is real-world consistent with a full-spectrum florescent on a 75 gallon tank. I made a trip to the pet store yesterday to verify that. The guppy is on the larger end of the scale but the fish are also actually actual size as verified by the trip to the pet store. Discus and angels can get even bigger, but then they also get meaner and dont co-habit well with more docile types. I framed it all based on the full sized fish (which may not have been advisable) just the same as when I stooped down in the pet store and looked at then from a distance of ten inches. None of the fish pictured hang out at the bottom of the tank, and when we were looking at each other, I wasnt seeing the bottom of the tank even if it was within my field of view, but I was seeing a portion of the foreground plants. Also, there werent really any shadows in the tank, or any real perception of front-to-back depth beyond the placement of the fish it was only about 18 inches there certainly wasnt murk in the tank, but the sub could certainly have the potential to kick some up even though it is probably a scale inch and a quarter. My hope was to have the fish be the primary focus and then for the viewer to discover the sub sub scene after a few moments. Id like help trying to sell these points if at all possible instead of abandoning them again if its possible to achieve I think the biggest challenge is trying to sell the quasi-overlap of one environment with the other and trying to balance the compromises. I could probably pull off a straight fish tank or a straight underwater scene, by Id like to try to marry the two even if it isnt working out as harmoniously as either single concept would be by itself. Maybe the whole cross-boundary thing gets in the way too much but I dont know where Id find a bunch of people to come up with a creative solution set than here if it is. Thanks and keep it coming
