Anatomy of a Hibiscus – Part 2 (Extreme Macro)

Hibiscus is a great flower to photograph. The contrast between the green sepals and bracts, showy red petals (this particular variety), deep red pistils surrounded by bright yellow stamens make a great study in contrast especially against a dark background. You may not enjoy the botany below, but I’m sure you’ll agree that nature truly offers a marvelous spectacle in the microscopic.

We all learned in school botany (well some of us!) about the various parts that make up a flower. Generally, flowers have 3 components –

  • Calyx – made up of sepals that protect the bud in infancy and form the base of the flower

  • Corolla – made up of showy petals that encase the reproductive organs

  • Stamen – that make up the male reproductive parts – in turn made up of the filament that holds up the pollen sac or anther. The anther releases pollen when open.

    • Pistil – The female reproductive parts of a flower. These are also made up of three components
      • Ovary – that finally forms the seed after fertilization
      • Style – a stalk above the ovary
      • Stigma – the farthest extend of the female part of the flower which receives the pollen for fertilization. This is usually sticky and allows pollen to attach.

The pollen in the above picture look spherical, don’t they? But in the picture below, which is a crop of the above, you can see that the pollen grains are spiky, thereby allowing them to stick to the stigma surface.

Well, that’s my botany lesson! Thanks for stopping by….

Anatomy of a Hibiscus – Part 1

One of my pride and joy has been able to sustain an oriental hibiscus plant (indoors) through the vagaries of British weather, and in return I’m blessed with vibrant red hibiscus flowers 3-4 times in a month, sometimes more. Here is a study of a hibiscus flower in original (untouched or processed, exported from Lightroom), B&W rendition (processed in Silver Efex Pro), processed using Color Efex Pro filters to bring out detail.

I like the picture as it was from the camera (untouched). Why process a picture if it doesn’t really add anything more to the photograph?

Thanks for stopping by, and please do leave a comment on what you think?

The world didn’t end today!

The world hasn’t ended so far today and it seems unlikely to do so in the next 8 hours left (or maybe the Mayan Calendar was just crap to begin with)!! But if it does in the next 8 hours and 22 minutes, I wanted to leave you with a couple of pictures in what could be my last blog posting!!

Did you spot the tiny spider in both the pictures on the middle-right of the picture? These flowers are those of the Lesser Celandine. Also known as pilewort since the plant was believed to be useful for the treatment of piles. Impressive knowledge to have if the world comes to an end.

 

Daffodil – on black

I know this is the middle of winter!! Just to cheer us up and to look forward to the lazy days of spring and summer, here’s a lovely daffodil on a black background.

Yellow Rose in Autumn

October gets over today, and cold rain and winds lash Cambridge. The nights come early. In the midst of all this, a single rose valiantly blooms for the last time in 2012.

Photographing Roses

Last week I had this really nice bunch of gold-coloured roses and I wanted to try out my photography skills using a remote flash on commander mode. I placed the flash on the tripod and right angles to the photograph with some interesting results. One of two of these are with the flash on the camera, but can  you tell the difference?

head-on flash
external flash behind roses
external flash behind rose to the right
external flash at right angles to the camera. Light coming from the left.
External flash right angles to camera from left. Longer exposure.
external flash about 45 degrees to camera in a V arrangement

The main advantage I found to having an external remote flash was to be able to play with the colours and backgrounds. No post-processing carried out for any of these pictures. The roses too look different depending on the light source.

Yellow Rose with dew drop – on black

This lovely photograph is from a close friend of mine who sent it to me a couple of weeks ago. I think this picture covers everything that is beautiful about a rose. I share it here with you with her permission. I have post-processed the picture to get a perfect dark background and remove noise from the photograph.

Begonias – on black

 

A begonia flower. My begonia’s grow from these funny looking corms that I have to dig up every winter after the first frosts and then replant them the next year. These have been going on strong for 3 years now.

The first image was processed in Colour Effex Pro. The bottom image is unprocessed.

 

Evening Primrose II – On Black

I went back to my Oenothera plant over the weekend and experimented with my SB600 speedlight in slave mode. These pictures were shot with the external flash roughly at right angles to the camera. The results are interesting!!

I didn’t have to work too hard to get a black background in either of these pictures due to the positioning of the external flash. I also notice that the colours are less harsh now that the light is not parallel to the lens. Compare with the earlier post on the same flowers.
