A Nikon D7000 equipped with a Nikkor 16-85 mm VR lens was successfully tested in macrophotography in picturing tropical butterflies. Even in full sunlight, too low speed (< 1/10s), aperture (<f/5), iso (100 ISO) and light must be avoid in most cases. This example was taken at 1/60, f/8 and 200 ISO, manual focusing, what seems the minimum conditions to get sharp images. But the main challenge remains the focusing as at 30 cm from the subject, the depth of field is about 1 cm à f/8, a few mm at f/5...

Recorded at home just after have bougth some flowers including this

Gerbera. Compositage made in PS in incrusting the heart.

I was thinking to my girlfriend in creating this composition, and offered her. I bought some flowers and did this compositage in PS

More that white light, infrared "light" allows an infinity of color variations during the postprocessing. This shoot was recorded in the Echernach park (Luxembourg) using an internal filter of 665 nm. Colors including luminance were then enhanced in PS and its plugins (first B/R channels were inverted to keep the sky blue and curves adjusted).

Taken with a Lumix LX5 defiltered by MaxMax (transmisison 330-1200

nm), under a X-Nite 630 nm IR filter (transparent from 590 to 1200 nm,

hbw from 630 nm), B+W polarizer, Custom White Balance on grass.

The original image shows a sky orange with a vegetation pale blue or

white).

Postprocessing in PS : swap of B-R channels to keep the sky blue,

auto-levels, hue/saturation corrected to reduce the color of trees and

cyan dominance in clouds, adjustement of luminance.

Picturing clouds through a porthole using a compact (without polarizing

filter and without manual focusing) is a challenge.

This image showing stratocumulus requested postprocessing in PS to

restore the sun aspect (much overexposed due to the porthole), reduce

reflections (but I kept some to enhance the overall scene), I had to

improve the clouds appearence and at last to balance levels.

The sea (Mediterranean close to Perpignan, F) visible close to the

horizon has orange glints (picture was taken at 7 am). Therefore I was

unable and didn't want to give a neutral color (white) to clouds in respect

with the light in this early morning.

NB. I thought that my compact could record such scenes without

processing. But it was impossible, first because this compact TZ10,

even using a Leica lens, only create JPEG files, then because the

porthole added many artifacts.

Conclusion : next time I will shoot with a Nikon D7000 in raw format.

For various reasons (subject, colors, feeling) this picture is much

appreciated (I sold some). I should be curious to know your opinion and

rating. Thanks.

It is a composit of 2 images or more that could look ordinary but it is not, really not.

Indeed even if the image resolution is low in this copy, we do not see any star trail or coma what reflects both the high quality of the photographic system and all the skill of the photographer. Superb work Yoshida San !

Waow ! Superb... Some many colors in one picture. Congratulations !

NB. The sky looks too magenta (even clouds). So that looks artificial.

Not original but always superb.

Good balance of colors, bright and dark areas. I 'd try to enhance the big rock in the upper left corner and to remove the left most part of the reflection (the pinky part) to improve the image.
