Dear Friends.

Sesamum Orientale, also known as "Ran Til" in Marathi, a very common flower found in Sahayadris. This one was photographed in Tansa Wildlife Sanctuary area in Thane district.

Ideally would have liked little more space at top, but to cover the bottom flower in full, and to retain original orientation of stem,had to sacrifice this element of composition.

EXIF : Canon 550D, Tamron 90mm Macro VC, Manual Mode, Evaluative Metering, Tv : 1/320, Av : 1/11, ISO Auto -800, 18% Cropped (82% retained).

Hope you like & enjoy it.

Regards/Anil Kumar Verma

It seems you have got your new lens. Congratulations!

Nice image. The colours look good. At the moment the leaft touches the top frame edge. Some more space at the top would have been great. Also, more space at the bottom would have been nice. You could also have clicked from a lower angle with the lens slightly pointing up. That would have reduced the out of focus bright green plant at the bottom right. Thanks for sharing.

Congrats on the new lens :). The bright violet colour looks nice. Good details. Looks forward to more macro images from the Tamron :). Thanks for sharing.

Thanks Sabyasachi Da & Mrudul ! Agree with your suggestions.

Still getting used to this new lens. Operating it is more difficult than I had imagined, especially with shallow DoF & subject movement , focus shifts so rapidly, that its frustrating at times in hand held condition.

Also , higher aperture no. presents a challenge to have a good shutter speed. Finally shifted to Manual Mode with ISO in Auto mode. With this ,most of the images shifted to ISO 3200/1600 and still under exposed. This one being an exception due to brief spell of sunlight on a cloudy day.

Any suggestions to best operate Macro Lenses.

Thanks again for suggestions.

Few things to remember:
1) Auto ISO: It has to be under control. Else, it will move way up and increase noise. It is important that as photographers we decide what ISO to use. So if you don't like the shutter speed, increase the ISO. Better not to let the camera make that decision as that may not be the optimal decision.

2) In macro photography when the subject is close, virtually inches away, the depth of field is shallow. So one needs to use narrow aperture f9/f11/f16 etc. Such narrow apertures reduce the amount of light and results in low shutter speeds. This forces to look hard at handholding technique as well as use any kind of support possible. Even a flimsy tripod or monopod helps a lot in terms of stability.

3) Macro photography is also tough because most of the times people unknowingly move forward and backward while clicking an image. In macro photography this results in the subject going out of focus or missing the critical focus when the shot is clicked.

4) In manual mode you can decide your shutter speed as well as aperture and ISO. So underexposure means you are getting it wrong. Please check the exposure tips in the photography tips section. If the image is underexposed then obviously there will be noise. One crude method is to check your exposure after every shot and then correct it. However, you should be exposing correctly to start with.
