Re: Communal flowers, trees, plants and fungi thread

Cardoon Flower Portraits with Improved 3D

These are when the flower has extended further. The last frame shows interest from a bumble bee and a hoverfly.

Again, I used triple flash. This time, the left unit was held in my hand, well forward and high, while I handled the camera with only my right hand, not an option for daylight exposure.

This was the flower at its peak of development. Within hours the stamens had shrivelled and many were detached.

Kiron 105, f16

Nikkor 24mm As Backup?

I recently invested in a Sony A7R body for wide angle and ultra-wide angle, non-macro, photography with my legacy lenses. My 24mm lens is the very bulky and heavy Zuiko 24mm shift lens. So when I saw this lens I thought it might be a good substitute, when I did not require shift function, and its close working distance might be useful for close-ups if I did not have my macro lenses with me (unlikely!) or had no time to change lenses.

http://www.mir.com.my/rb/photography...wides/24mm.htm

To clarify, it is a Nikon Nikkor-N Auto 24mm f:2.8 Non AI. I was awaiting an adapter but found that my Pentax K held the lens but would not lock it on, so that it what I used. As there is a difference of 1mm in registration distance between Nikon and Pentax, the working distance will have been a little different than the nominal.

I obtained one this week and have tried it out at its closest working distance (see above) of 1 foot and at 1.5 feet. The A7R has no IS so I used f11, rather than my customary f16 but expected it to be adequate. I am not looking to get frame-filling macro images but to have reasonable close-ups.

These images are from the first session and have been checked for motion blur. There is a crop from the first one, from the processed image, Ideally the crop would be processed from scratch. There were shot as RAW files in daylight.

Re: Communal flowers, trees, plants and fungi thread

Sony A7R & Nikon 24mm: Sunflower.

There were only two flowers, both close to a fence, beyond which is our neighbour’s greenhouse, with very old and fragile glass. With rather uneven ground on our side, and a wobbly stool to support me, I took no longer that was absolutely essential to frame and focus. So I cannot verify the exact closest focus position but I was a little too close for the near edge in the last image. The two close-ups have been checked for motion blur and are uncropped.

I show a crop (of processed image) of the first image to show the detail.

Exposures were by sunlight at f16 1/1000 sec at ISO 800. Shooting almost towards the sun, I did get a tiny hexagonal flare which was easily cropped out. I have used some digital fill to moderate shadows. (There is some minor dirt on the sensor).

Sony A7R (aperture priority), Nikon Nikkor-N Auto 24mm f:2.8 Non AI*, hand-held.

David,

Nice shot. Yes they did. They were not sure that it would catch on.

I Googled it after posting the shot. It never occurred to me that Velcro is a brand name and the generic name is hook and loop fastener. And according to Star Trek it's going to be invented by a Vulcan of the same name as the human inventor.

Just as "Hoover" has become a generic name, so has, in effect, Velcro.

My wife and I have owned washing machines and dishwashers with the Hoover brand name but always Dyson vacuum cleaners (no vacuum ever needed cleaning!). I take advantage of this when being asked to help with houseowork.

Yea I was thinking of Hoover as another one. Biro was another when I was still in the UK. Over here Kleenex and Ziploc are others.

Viagra will be the next. It will have to stand up against stiff competition.

Re: Communal flowers, trees, plants and fungi thread

X-Pan 90 on A7R: Sunflower

I recently showed what the Nikkor 24mm could do at its closest working distance of a foot (30cm) on full frame. Another lens, which shares thesame working distance, and , as I found, the same closest FOV, is the XPan 90m.

I have used this lens for moderate macro, sometimes with a Marumi supplementary, on m4/3 but this is the first venture into FF. It is rather close in FL to my Kiron 105 but is a quality lens and may have applications. (I can carry only so many lenses!).

The sunflowers are the same ones used for the 24mm shots. The sunlight was much the same but with the sun further to the left. In this particular circumstance I was able to be safely on the ground, rather than balancing on a stool next to a green house. The lens is of the same focal length of many FF portrait lenses and gives a more normal perspective than the 24mm,

The closest shot, with crosseye stereo, was not shot as a stereo pair but my several attempts at framing came up with a pair as good as I might have intended.

There has been some digital moderation of shadows.

A7R (manual mode), X-Pan f4 90mm 1/1250 at f16, hand-held.

Carrot Fruits: a 3D Delight.

I have posted many images here of insects feeding on the florets of the white umbel of the wild carrot. It remained in flower for many days whereas other wild umbelifers in my garden were over in about two days. These spiney structures are the dry fruits which contain the seeds The spines are on the D-shaped half, the back of this being flat with two longitudinal ridges..The fruits are about 7mm long, a bit big for the 6mm FOV of my reversed HM40 setup.

It is tricky to find photogenic groups of fruits amongst the massed hundreds. I have, therefore, included one group with a bit of gastropod slime on it. The stereo is crosseye.

Olympus EM-1, Kiron 105mm or reversed Schneider HM 40 + x1.5 TC, twin TTL flash, hand-held with some support from the worktop.

Re: Communal flowers, trees, plants and fungi thread

Safflower Bud & Flower with 3D

Safflower, Carthamus tinctorius, is a crop of significant and diverse importance, for its oil, as a source bird seed and animal feed and much more besides, including medicinal uses. I received a free gift of seeds with a flower seed order. These plants reached grew to only about 25cm high (due to late sowing) but would normally reach 150cm. The flower can be yellow, orange or red.

The shots of the open flower are at an angle to hide a damaged leaf, a problem with all three available plants. The bud measures ca 20mm at its widest part.

EM-1, Kiron 105mm, f16, twin RC TTL flash, hand-held.

A couple of shots of Sunflowers growing in the yard from bird seed.

This flower, opening for the first time for me, provided a lovely setting for recent spider and butterfly shots. I think you will agree that it deserves a topic of its own. These flowers have considerable similarities to irises. However, the petals are held more upright, giving the flowers a slightly foreshortened view from the side.

These were taken in overcast daylight about and hour after prolonged rain ceased. In theory, this is classical lighting for flower photography. The stereos are crosseye.

EM-1, Kiron 105mm at f16, 1/100 & 1/125 second, hand-held.

I think it is a really lovely colour and shape. Plus the rain drops are perfect dressing. Glad you posted it.
