Corals, despite their colorful and sometimes cartoonish appearance, are fierce predators. At night they open up, extend their tentacles, and start munching on anything that they can digest. Which is mostly plankton, but they are also intolerant towards neighbors and wouldn't hesitate spitting some deadly guts on members of other coral species.

This one is Scolymia sp.

An alveopora coral is beautiful up close. The image is a focus stack. Fluorescent colors are natural and become apparent under ambient underwater light at depth of 5m or more.

it's a tank shot, albeit the coral is freshly collected and natural spectrum imitated. You can't get this quality underwater

Rhodactis corallimorph under full-spectrum lights to imitate the natural underwater illumination and bring up fluorescent pigmentation.

This is a focus stack that took me several hours to get right as the animal moves a lot. As a result of the stacking process I was also able to create a stereo image, which allows to understand the shape of the invertebrate better.

An incredibly colorful coral. A stereoscopic image available here: http://tiny.cc/1huu1w (cross-eye version) http://tiny.cc/1iuu1w (various 3d formats for 3d screens). So amazing to see how corals increase their surface area in this way.

The image taken under full-spectrum light to bring out fluorescence that is left out when illuminating them with strobes.

Any canon dslr with magic lantern installed can do so. But since I use mp-e 65 mm lens, the only way to change focus is to move the camera. So I use Stackshot. It's an automated rail that also triggers the camera.

Acanthastra lordhowensis under some magnification. This is an incredibly detailed image. You can see a close-up of this photo here: http://tiny.cc/u89g1w to get an idea of how much details can be seen on this image in full resolution.

For those who know how to see cross-eye stereos, it's available in 3d: http://tiny.cc/qaah1w

Yellow is pretty rare among hard corals. Yet, nobody was able to properly identify this specimen.

Yellow pigmentation appears solid. But a closer look with a lens reveals spots out of which the colorful middle part is made.

The image is a focus stack. 5D mkiii + MP-E 65 mm

This amazing rainbow lobophyllia coral reminds me of how important it is to be aware of fluorescence underwater. Fluorescence transforms wavelength of light instead of just absorbing and reflecting it. Under white light from torches and strobes this coral would be brown. Under ambient light or imitated underwater spectrum it turns into rainbow explosion!

When you are underwater and have a torch, try turning the light on and off when looking and random creatures and see the difference yourself. Doesn't work on sea star and sea cucumbers, this trick is more relevant to hard and soft corals.

I can't stop looking at 45x30 inch print of this animal and finding new details up close.

As colorful, bizarre-looking, and environmentally important as we know corals and sponges are, their simple day-to-day life is hidden. They might not seem exciting when it comes to motion. However, their speeds simply happen to be out of sync with our narrow perception. This clip shows them from an unusual perspective: high magnification, focus stacking, and full-spectrum illumination that brought out fluorescent colors.

Learn more about what you see in my post: http://notes-from-dreamworlds.blogspot.com.au/2014/03/slow-life.html

To make this little clip I took 150000 shots. Why so many? Because macro photography involves shallow depth of field. To extend it, I used focus stacking. Each frame of the video is actually a stack that consists of 3-12 shots where in-focus areas are merged. Just the intro and last scene are regular real-time footage. One frame required about 10 minutes of processing time (raw conversion + stacking). Unfortunately, the success rate was very low due to copious technical challenges and I spent almost 9 long months just to learn how to make these kinds of videos and understand how to work with these delicate creatures.

Enjoy on a big screen to be able to see individual cells in sponges and tiny details in corals. Available in 4k.

Some pond animals might not look attractive at first glance. The majority of people who encounter a bryozoa colony most likely wouldn't recognize what it is. A hairy warm? A weird hydrozoa? After all, even the mention of words "bryozoa"and "moss animals" alone provokes only one question—"what the heck is that?" The truth is, molecular taxonomists have more or less the same question when approaching this group.

Bryozoa are among the least studied invertebrates. According to phylogeny analysis they are not relatives of cnidaria or, in fact, any known group of invertebrates. Some evidence suggests that they might be related to even less studied group of organisms—Entoprocta. But leaving phylogenetic and taxonomic speculations aside, bryozoa are colonial filter-feeding animals that are really abundant in freshwater and marine habitats. Their polyps are tiny and almost invisible to the naked eyes. Yet their colonies can reach up to several meters is size, although such giants are rare.

The animal on the picture is a very unique organism Cristatella mucedo. Not only it's notorious for forming mobile colonies that crawl like snails, it also has a very peculiar body organization where individual zooids are differentiated like cells in a multicellular organism. Zooids can participate in feeding, locomotion, or breeding.

You are welcome to see more pictures and find a bit more info about this fascinating creature in my blog post: http://notes-from-dreamworlds.blogspot.com.au/2012/04/mysterious-bryozoa.html

I love coral macro. But the more I've been doing it, the more I realized how much I miss the perception of volume and depth on still images. That's why I decided to try 3d photography. Stereoscopic photography, to be more precise, which is quite easy to do with focus stacking.

A focus stack is an image composed out of photos taken at different focus distances to increase the depth of field. Each photo has in-focus and out-of-focus parts. That means that technically a set of images will have three-dimensional information. Stacking software can recognize the in-focus parts (X,Y coordinates) and normally it copies them to the images where the corresponding  areas are out of focus. So, Z axis here corresponds to different images in a stack, each one having different in-focus X,Y. However, while the stacking process occurs, the software can also offset the in-focus layers for a certain distance. Instead of putting the next in-focus layer at exactly the same location where it was on the previous image, the layer is, for example, shifted 5 pixels to the right or left. As a result, an offset will make the stacked object appear to be photographed from a different angle. 

Unfortunately, though, stereoscopic screens are not very common yet. The good news is that glass-free display are on their way. A few smartphones have been available for a while, and this year has brought 3 or 4 tablets that show a 3d image without glasses at any angle. And this technology is advancing fast. For example, the mentioned tablets are just a hundred dollars more expensive than their regular alternatives. I believe in 5 years or so most of laptops will have a stereoscopic screen and stereo photography will take more visible position. For now, it's just a gimmick, but one that allows to experience images in the way that they are meant to be seen with our brains that are designed to work in stereoscopic format.

If you happen to have a 3d display of any kind, you are welcome to take a look at my new 3d gallery here: http://phereo.com/Starshade
If you don't you still can use such poor method as anaglyph or, in the worst case, wiggle.

The animation below is a macro of an acropora coral made out of a single stack. Sorry for some artifacts around the closest branch--I didn't have enough time to clean everything. Such issues do not appear in stereoscopic images.

+Daniel Stoupin Wow man, zillions of photos and different focus distances do you normally use for a shot of this nature... really incredible to try and begin to "TRY" and understand your processes.

Many animals can see linearly polarized light. Marine invertebrates such as cuttlefish and mantis shrimps, aside from seeing it, can actually use it for communication. We know that amphipods are also able to detect polarized light and researchers speculate that similarly to bees, these crustaceans use this type of vision for navigation. After all the sky has very clear and reliable polarized patterns. However, some photographers know that amphipods are also spectacular when seen through crossed polarizers. They have many types of interesting patters. Yet nobody has studied if these patterns are used for communication in this animal that most likely can see them.

See more pictures and read about polarized light vision in my blog post: http://notes-from-dreamworlds.blogspot.com.au/2013/07/polarized-vision-amphipod.html
