The River Test south of Andover. The river rises near the village of Ashe, and flows west through the villages of Overton, Laverstoke, and the town of Whitchurch, before joining with the Bourne Rivulet at Testbourne and turning into a more southerly direction. It then flows through the villages of Longparish and Middleton to Wherwell and Chilbolton, where the Rivers Dever and Anton contribute to the flow
New camera test shot. Not meant as a great artistic shot, but the new camera loves Loki. This is on auto with a flash. Not what I would have expected from any flash photo, but I'm pleased. I have so so much to learn!
Test av ti redningsflåter sammen med "Seilas" og "Båtliv". Det ble testet to redningsflåter fra hver av merkene Eurovinil, Viking, Zodiac, Plastimo og Arimar.
Romsey Town Rollerbillie Aimee Lack's roller derby name contains no irony or pun, her daytime job is testing software.
Testing out my new Canon RF 800mm F11 lens this morning. (Not the best composition with the Mourning Dove, but I wanted to critique the focusing quality of the lens today). Although this lens is definitely light and hand-holding is do-able, I'll probably stick to mostly using a mono- or tri-pod. I'm too shaky most days and the 800mm can be pretty unforgiving with the slightest wobble from me! All in all though, I'm happy with the results I got today. (All five shots were taken with my camera resting on a beanbag in the car window).Will this be my "go-to" lens for everyday wildlife photography? Maybe not...(I still have my eye on the RF 100-500 lens), but it was AFFORDABLE (and George Lepp gave it a great review a few months ago, so I was sold.) It really is a great lens in the right shooting conditions and I hope to get better as I use it more often, once our summer heatwave is over.
I would love to hear from others who own this lens and have any tips or tricks they use to get the best possible shots.

I love this shot taken of a Ford Anglia and a Morris Minor being used for driving tests in Valetta in August 1988

This was a test of shooting the interior of a JR. I used a Nikon D90 with 6 images and my most anti-establishment lens, the 100 dollar 18-55mm VR lens. Post was done Lightroom using "stacks" and then exported to CS3 for the stitch and final adjustments.
No flash was used, this is all ambient light and the use of layers in post
The plan is to go back before the official opening and do the shoot in the AM. This was around noon. I have to get the view out the windows right on the money.
Currently use a Moleskine for my daily journaling and I love it... when writing and doing pen work anyway. I don't like how the paper performs with water though. Sooooo, I've been thinking of making my own journals and have been test papers. I want the thinnest paper possible that will perform well with watercolor... Think I've found a winner!
Nikon CFI Plan 10x/0.25NA 10.5mm WD objective mounted on Canon EF 100mm f/2.8L Macro IS USM + Canon 5 D Mark II. This combination yields 5:1 on the sensor, i.e. 1 mm on reality projects to 5 mm on sensor.
I used continuous lighting with two 32 W full spectrum daylight lamps (CRI 97).
Left:
focus step size 0.01 mm
stack size 50
MLU ON
EFSC ON (silent mode = 1)
wait after stepper movement = 1s
IS (image stabilizer) ON
Right:
same as left but
IS OFF
There is really no difference between the pictures. So whether IS is On or OFF makes no difference in my setup.
Technically using Image Stabilizer together with camera mounted on tripod is quite complicated. Canon's own doc. pages have this info:
Using IS with a tripod
When using certain early models of IS lenses with a tripod it was necessary to turn off the IS function. This is because of a phenomenon known as ‘Shake Return’. Shake Return occurs when the IS system tries to correct vibrations to which the system itself contributes. When the IS lens sits on a tripod, the IS detection gyros pick up any tiny vibrations or movement; these might be caused by the tripod being knocked, or the photographer adjusting a camera setting.
The IS system then swings into action to correct that movement. The movement of the IS lens group causes its own minute vibration, which is in turn detected by the movement sensor, which triggers another correction. This ‘feedback loop’ can continue endlessly, resulting in the addition of unwanted blur to images that would be sharper if the IS function was switched off.
Canon addressed the ‘feedback loop’ in later model IS lenses by introducing an algorithm to the IS detection system to automatically recognise when the lens is mounted to a tripod. When these lenses are mounted on a tripod and the shutter button is pressed halfway, the IS system kicks in and the image in the viewfinder can be seen to go through a very slow vertical shift for about one second.
If the shutter button remains depressed halfway the IS system detects the lack of motion and automatically switches into a special mode. In this mode IS detects and corrects for mirror slap and shutter movement at slow speeds, but not for ‘normal’ lens shake. There is no advantage to be gained in turning off the IS function or locking the mirror prior to exposure.
The early model lenses which do not have this automatic function and which should have IS turned off (ie lock the IS correction lens group in place) when mounted on a tripod include the following lenses:
•EF28-135mm f/3.5-5.6 IS USM
•EF75-300mm f/4-5.6 IS USM
•EF100-400mm f/4.5-5.6L IS USM
•EF300mm f/4L IS USM
Even though IS ON/OFF did not make a difference in my test I think it is better to have IS turned OFF when stacking with microscope objectives.
