Photosynthesis

Photosynthesis Beneath The Sea

Photosynthesis

Most reef-building corals contain photosynthetic algae, called zooxanthellae, that live in their tissues. The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes. Most importantly, zooxanthellae supply the coral with glucose, glycerol, and amino acids, which are the products of photosynthesis. The coral uses these products to make proteins, fats, and carbohydrates, and produce calcium carbonate. (Source: NOAA Ocean Service Education)

We got to see these coral polyps and their symbiotic algae photosynthesising, under UV light, in the educational Underwater World aquarium at Birdworld in Farnham. It’s mesmerisingly beautiful! The colour that we associate with coral reefs is derived from the algae living within the tissue. When a reef is put under physical stress, the coral polyps actually expel the algae leaving the structures a stark white. This is the tragic, mass death of large areas of reef that we call “bleaching”. Seeing the living coral made this disatrous phenomenon all the more real to me. I’m posting this image for Wex Mondays this week and I hope that it will lead others to think about the plight of our precious coral reefs.

One of the great joys of visiting a butterfly house is the ability to see large, tropical butterflies up close. Every single tiny and perfect detail of these beautiful creatures is revealed. The wings are a mosaic masterpiece of scales and hairs that will allow the butterfly to blend perfectly into its’ surroundings, or send a bold warning to potential predators. The malachite is a master of disguise but the macro lens allows me to bring you the finer details of it’s camouflage. This was taken at RHS Wisley Gardens last Monday while I was volunteering for the Surrey branch of Butterfly Conservation UK, helping man our stand in the Glasshouse, during the annual Butterflies In The Glasshouse event. I really enjoy engaging with the public at this event, sharing my passion for butterflies of the UK and Europe, as well as the tropical species. I’m sharing this macro for Wex Mondays this week and I hope it will inspire others to look more closely at butterflies too.

Encapsulate

Encapsulate

This last week has been a complete write-off thanks to sinus and chest infection. I know many of you have suffered similarly just recently! I’ve been back at the doctors today for stronger, more targetted antibiotics and phlocodine. Increasing my steroid inhalers has helped me breathe a little easier today but it always gives me the shakes. In short, I’m totally fed up! I just about managed to set up a piece of blown glass yesterday, so I could take a series of macro shots, from which I created a composite for today’s photo challenges from Wex and Fotospeed. Encapsulate is an abstract expression of how I have been feeling with this bug; trapped, dizzy, fuzzy, short of breath, drowning in mucus. If you’ve had one of these Winter bugs, I hope you are on the road to recovery as I very much hope for myself! I don’t do well being stuck indoors. The winter skies, misty landscapes and busy birds are calling to me!

Upon Reflection

Fading Out

Upon Reflection

I had another go at focus stacking this last weekend. This time my subject is botanical, the decaying petals of a hydrangea. They’re all from one flower-head but all at different stages of decay, from the age-spotted pinks through to skeletal lacy remains. The petals were arranged on glass on a black background and lit with a diffused, blue spotlight. After stacking my images in Photoshop and masking in the focused areas, I decided that the image felt more appealing, almost vintage, with some areas left soft and unfocused. I gave the whole piece a hazy, matte finish to accentuate that vintage look that is a mirror to the subject itself. I hope you like it! I’m putting this one forward for both Wex Mondays and the Fotospeed challenges this week. Good luck to all taking part!

This leaf is one of the many, fallen from the sycamore in our communal gardens. I love collecting the leaves from this tree to create macro studies from. I usually keep them all in colour, enjoying the vibrancy and richness of the many tones. This particular leaf really lent itself to a monotone study though. It’s my entry for this week’s Fotospeed challenge. Good luck to everyone taking part!

Spider

Araneus

My Fotospeed challenge entry this week is of the humble garden spider, araneus diadematus. Our garden is almost overflowing with them at the moment! Fortunately I’m not afraid of spiders, they genuinely fascinate me. I’ve been meaning to try focus stacking for macro images for quite a while now. This spider was in a sheltered spot on the back door, keeping nice and still for me to get close with my 30mm and capture 20 frames, handheld, manually adjusting the focus. I combined the images in Photoshop, using masks to brush away the unfocused areas and reveal much more detail of my subject than I would have been able to capture in a single frame. I have a long way to go to get to where I’d like to be in this area of photography and processing techniques, but I feel like I’ve made a relatively good start. Lots to learn and even more equipment to acquire! Any advice would be gratefully received.

Ready For The Close-Up

Dragonfly Macro

Ready For The Close-Up

I suspect that this dragonfly, at RHS Wisley Gardens, had only recently emerged when I found it yesterday. I wouldn’t usually be able to get this close to one! They have incredible eyes that take up most of the head, allowing them to see almost all around them and in higher definition than we mere humans could ever hope for. This is my entry for the Fotospeed challenge this week. Good luck everyone!
