I always telling friends of mine to have bigger aperture to get clearer Milky way shot … and it really give impact with more light fall onto the sensor … but what if we do not have big aperture len .. e.g. we own F4 or F3.5 lenses ?
theoritical , if we can increase the shutter time which allow more light abosrb on the sensor.. we should able to capture beautiful stars sky … but according to the rule 600
…
I had aiming a polarie star tracker but too bad, i had been turn down by the cost and size …
recently, I managed to test the
Vixen Polarie… a square box size small and weight <1kg … and not really difficult to operate …
i may not able to share how do use this .. but it is really simple and let me share the simple test result
both shoot at F4 , exp 151s +- , ISO 400
1. without start tracker – Vixen Polarie
2. witho start tracker – Vixen Polarie
with minimu setup time and minimu knowledge of Astronomy , I am able to create a image without “start trail” effect
**** rule 600 simply basic rule to avoid “star trail” effect while we have too long exposure on our effective focal length.. e.g.
16mm on FULL frame, we should have max exposure of 600/16=37.5s
16mm on canon APS-c , we should have max exposure of 600/16*1.6=23.4
so if we have anything more than the exposure time the the rotation of earth will create “star trai;” effect create blur effect on to our frame.
*** it is not showing right or wrong, but it is personal preference … some prefer static and some prefer movement ……..
update 2013 Jan 2
… ready to go … with Big Stopper
Some time we just need something slow … but smaller aperture and lower ISO .. but the speed still not low as what we want … then we need to make use of ND filter to slow down filter to create effect what we wish to have …
e.g. of use Big Stopper to make shutter >30s or even >60s … to create the silky and clouds movement or we call slow shutter
i love this filter even it create blue cast which can easily correct … I share some pictures before HERE
and this filters can be pre-order and I have constantly stock arrive … feel free to contact me …
not easy to find sample regard what this glass about … finally it is on my hand to have a try … a glass to enhance magenta, red, yellow and feel it really good for dawn light …
both picture with
1. Singh-Ray RGND 2 stop
2. AWB
3. both capture within 1 min
4. same iso, aperture … shutter speed had minor different due to additional glass
A. dawn with Singh-Ray RGND 2 stops only
B. dawn with Singh-Ray RGND 2 stops and Lee Filter Glass Enhancer
some may prefer original blue + yellow contrast .. and other may prefer magenta tone …
for me, photography no right and wrong .. just what we want to capture … and we may use it to enhance the magenta/yellow/read tone inside our frame
If you look for Lee Filters/SIngh-Ray stock available list click HERE
or contact ME for pre-book [Enhancer no more in Production due to Material shortage by Lee FIlters]
a beautiful bird .. and it love to stand on the banana flower … and these pictures were capture from 2009, 2010 & 2012 … (ohh .. I missed out 2011 …) and if someone ask me will I go back to the same place next year for the same bird + flower …. my answer is YES 😀
was my first experience shooting fireflies from top … look awesome … too bad the timelapse need more time to prepare .. so let me share the picture I capture …
will have more to share about fireflies .. and I think I fall in love with it …
A slim, medium-sized drongo with bright red eyes and gray plumage that is almost black in the western parts of its range and quite pale in the eastern parts of its range; eastern birds also often have an oval-shaped pale facial patch. It has a long slim tail with a deep fork. Common in wooded habitats where it sallies for insects and aggressively chases other birds that may compete for food or nectar. Most birds migrate south every winter. Similar to Black Drongo, but slimmer and usually in different habitats. Calls include harsh and sweet notes, and can mimic some bird species poorly. [Ebird]
It is noticeably larger than the Ashy Drongo found in Malaysia. We were fortunate to spot it catching a wasp (recently, I got stung by a wasp in Sumatra—glad this bird took care of one for me… just joking!). This bird is quite common at Baihualing and can be seen from several different hides.
