10 stops filter exposure table

to make my life easier, I always keep this table with me while I use my 10 stops filter

10 stops exposure
1/1000 1 sec
1/800 1 sec
1/640 1 sec
1/500 2 sec
1/400 2 sec
1/320 3 sec
1/250 4 sec
1/200 5 sec
1/160 6 sec
1/125 8 sec
1/100 10 sec
1/80 12 sec
1/60 17 sec
1/50 20 sec
1/40 25 sec
1/30 34 sec
1/25 40 sec
1/20 51 sec
1/15 68 sec
1/13 78 sec
1/10 102 sec
1/8 128 sec
1/6 170 sec
1/5 204 sec
1/4 256 sec
1/3 341 sec
0.4 409 sec
0.5 512 sec
10/16 640 sec
10/13 787 sec
1 1024

for anything before 1/1000, our camera should able to give correct exposure … and for me anything more than 1000sec is almost too long to wait for .. so I will only use the filter

 

this formula is apply for

mySchneider – nd1000x or my Big Stopper

10 stops ND filters (Schneider – nd1000x) on Sales

and some of my Long Exposures pictures

Long Exposures Gear – Big stop ND

Long Exposures Gear – Big stop ND

Even on day light ? At bright condition how we can get silky feel on sea/lake/river etc ….so normally we will use a big stop of ND and in the market have few well known

1.  B+W/Schneider 10 stops filter (nd1000x) (10 stops)

2. Lee Filter Big Stopper (10 stops)

3. Hoya400 (9 stops)

At daylight (Malaysia), even with smallest aperture & lowest ISO … we still will get something 1/400-1/100… e.g. even with 1/100 we will never get the silky effect

slow shutter at Dungun

and this was shoot early morning where already bright enough to fail you to make silky wave…by using the “Lee filter – Big Stopper” I shoot with exif below

# Exposure Time (1 / Shutter Speed) = 116/1 second ===> 116 second
# Lens F-Number / F-Stop = 11/1 ===> ƒ/11
# ISO Speed Ratings = 200
# Original Date/Time = 2010:12:18 07:26:43

 

or with sun still on the horizon, I still able to make the shutter to 20s to create the silky as exif below sharing

... difficult to reach ...

5dm2 + 1635@18mm + Lee Big Stopper + Lee .9s GND
# Exposure Time (1 / Shutter Speed) = 20/1 second ===> 20 second
# Lens F-Number / F-Stop = 9/1 ===> ƒ/9
# ISO Speed Ratings = 100

My 1st Milky Way …

it is not a dream, we able to shoot the Milky way at not really too dark area … it was my dream to chase it 2010 but some how I failed to make it … but 2011 me and my few close friends (shunfa, Lio, Jason … SP …. Mingkai) have start our crazy chasing project where we travel  ~400km (return) 3 times in a week …. even we try to make it coming weekend but due to the some security issue at the location so we decided to cancel our trip there ….

one of the failure Milky chase

My friend – Shunfa was so happy while he 1st got it with him 30mm F1.4 … and too bad what I have much obvious compare to what he has, not matter what setting I use (high ISO, long exposure, ISO NR, LE NR … ) but my F2.8 lenses still cannot get any clearer Milky as compare that 30mm F1.4 got … hmmmm so the conclusion is under not so dark place. it is always good to use bigger aperture lenses to have more stars, brighter stars (so thicker star trail) and more objects (Milky way) …

the Milky way

let’s me share my setting and some PP done on this

Canon 5dm2 + Canon 15mm F2.8 + tripod for sure
# Exposure Time (1 / Shutter Speed) = 43/1 second ===> 43 second
# Lens F-Number / F-Stop = 28/10 ===> ƒ/2.8
# ISO Speed Ratings = 500
– no Manipulation  done ..
– crop both site to make square look (no crop on top and bottom)
– some dodge and burn on the sky

and previous share How I shoot Stars..

How do I shoot Panorama 360×180

it is not easy to make this without the right tool but I think with handhold + some basic tripod we still able to shoot this … I am using Panaroma head , previously I was using Manfrotto 303SPH but very soon I make decision to change to Nodal Ninja due to the flexibility(dissemble to smaller part) & the weight (it is ~4 times lighter)

Compare the competition and avoid falling into the red.

My original plan for this head is to shoot Panorama shot using UWA wide so I can get higher resolution and wider view of my Landscape shots e.g.

http://www.liewwkphoto.com/gallery4.htm

But I know it can create spherical pano and 360×180 pano still so I had tried few times to make some shots …as below

and it also can create still rotational view @

http://www.liewwkphoto.com/still/PD/whereweshoot/PD2011Feb.htm

But then, how do I shoot this ?

1. we need the tool , and for me Nodal Ninja, DSLR and lenses

2. then the only difficult part is to find the entrance pupil/nodal point , a point where it should maintain the center no matter how we rotate our camera

if you are lucky then yours’ setup should listed @ http://www.nodalninja.com/support/camerasettings.html.. else you need to find one

2i. the bottom axis is fix by camera (refer as A on link above)

the other should depend lenses and focal length (refer as B on link above)

Entrance Pupil

2ii. use a close value base on the web site above put 2 stick together

How to find Entrance Pupil
Where to shoot while find Entrance Pupil

2iii. rotate yours pano head

how I rotate my pano head to get Entrance Pupil

2iv. no matter how we rotate, the 2 stick should maintain at same position

at center

left from center

left from center

right from center

right from center

try to adjust as much as possible to get better result so we can can accurate entrance pupil so all the frame of the picture can stack without any distortion

3. with the correct reading and shoot the series (make sure every pictures have overlap area)

3i. with the software Photoshop or PTGui (pano software) all pictures can be stack together as below

here is the result …

#######################################################

with the reading above then we have the specify len Entrance Pupil which can use to create panorama or 360×180 pano with the setting just shoot with both A & B reading set on the pano head ….

I will keep this update, which mean I will do more pano using this head in near further .. so stay tune ………

and if you use Canon 5dm2

i. SIGMA24mmF1.8
ii. Canon 24105F4L
iii. Canon 1635L m2
iv. Canon 15mm F2.8

and need the entrance pupils … then drop me a message so I can share my reading to you

The Light is Back – Port Dickson (Pantai Pasir Panjang)

for the pass 2-3 months we had real bad weather where most of the time sky were full of cloud … and we had stop almost all sunrise & sunset activities except going for some long exposures and luck trying …

Last week, we went to an old spot – Pantai Pasir Panjang – Port Dickson which discuss previously… with not high hope but the light simple amazing with beautiful magic moment … (and why I say maagic moment as it just happen for 2-4 minutes)

Dec visit where we had no choice to make long exposure shot instead

and for last week …

and hope the light will be continue and I will be back in action !!!!

Nightscape – How I shoot the stars and Milky Way …

update an old share from previous old blog site How I shoot stars.

it is not difficult to shoot stars as long as we have the luck and right setting, and let me share some of my experience… but it is fun and tiring for sure ……

as Earth is rotating itself, so all the stars are moving (except for the Poles star, North star, or call Polaris)… so while we shoot the sky for more than certain time the stars will become either lines or circle (depend which direction, how long you shoot usually >30s small line will be appear). to avoid this, extra telescope equipment (e.g.Losmandy G11 with Celestron C8), we can either shoot a star trail or max ~30-50s else the star will be look like a small lines instead of blinking stars….

e.g. of 727s single exposure

and sample of 30s

– I do not own one those equipment so I do not know in depth .. but basic is those equipment will auto trace the stars so we can have longer exposure (which really need it while in real dark environment and do not want to shoot super high ISO

so … I shoot as below
1. star trail

a. in real dark environment, make a rough estimation of exposure with setting below
i. biggest aperture as possible
ii. infinity focus
iii. manual focus
iv. mirror lock up
v. high ISO normally I use ~400-1600 depend the environment
vi. for the exposure depend on the light pollution … may need few try to get right exposure
vii. shoot 2 picture .. the sky one could be very long and make the foreground over expose. so shoot another exposure for foreground

– refer picture above expose 700s in single shutter

b. not so dark environment
i. biggest aperture as possible
ii. infinity focus
iii. manual focus
iv. mirror lock up
v. high ISO normally I use ~400-1600 depend the environment
vi. shoot 10-30s depend how bad is the light pollution
vii. set shooting mode to continuous shooting, and use remote to continue shooting for >20mintues (you should see some line or curve depend which direction you face)
viii. shoot 2 picture .. the sky one could be very long and make the foreground over expose. so shoot another exposure for foreground
viiii. use a software call startrail.exe (google it) or StarStax (MAC) and it can auto stack the all shots into single frame which combine the star as line/curve

or check out here
x. shoot north and south 😀 , if possible… if you prefer circle/curve compare to lines
xi. I use a software load into my android call skymap .. real coold application, you should have it , if you love night photography

so here is few sample for option b

~40minutes exposure

exposure of ~30minutes of F2.8 @ISO800

 

to capture Milky Way, it is almost same like a star but it is more sensitive to light pollution and rotation.. (mean star trail , and we try to avoid that for Milky way as it crease blur cloud object instead the beautiful milky way)

we may need to take note of rule 600 where

600 rule 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 trail” effect create blur effect on to our frame.

 

with minimum light pollution .. the color of the milky will look so beautiful

.. Milky from Bake’lalan …

from Bali …

… Milky way from Bali …

 

e.g. of light pollution

… city light pollution …

 

and Milky way near city (Kuala Lumpur) .. not viewable by nake eye .. but make use of big aperture len .. it can be capture

… city Milky way …

Nightscape – weather getting better

I found this place ~2 years ago while I look for macro spots but accidentally found this is a nice place for birding (birds seem not too worry/shy to human) ….

While I revisit this place last few weeks ago, found this is a good spot for nightscape, sunrise, and sunset too …. so decide to travel ~160km from KL toward north … while we reach we are shock with the stars and the stars reflection on the lakes ….

within 48 hours I make 2nd visit and continue to shoot the star trail .. which I stop sharing months back due to the bad schedule and weather ……….

45 pictures stack
each 40s , ISO800, F2.8 (Fisheye)

5dm2

I am sure this place going to be another famous spots for night scape, sunrise and sunset soon … but before I share out the location let’s me check is this private area or public 😀

Landscape : Will you go out for Photography while Monsoon Season ?

every year Nov -Jan , Peninsular Malaysia will have Monsoon season or we call raining season … some places of east coast of Malaysia always face flood issue after days raining … and most of the fisherman stop go out to sea due to the bad weather ….

Most of the photographer will get rest this period as normally the sky look cloudy … wave is too strong …. but I have the plan to shoot the wave, slow shutter … and if luck on my side then I can get strong wave hit the rock .. so  I went there 2 times 2010 for my wish …. even though we not seeing any sun at all for ~6 days trip but I still enjoy the strong wave … and beautiful places found (thanks Yusri, Azizi & CK Zinal for bringing us there…)

a quick capture how strong is the wave

even we missed out the beautiful egg yolk

but we still trying our best to get some slow shutter shots

cloudy day is good too

How Shunfa shooting a slow shutter in this type of environment … and video below show how he shoot slow shutter without filter holder 😀

there are few issue shooting in this type of environment

1. get ready be wet, get extra shirt, pants ….
2. protect your gear
3. solid tripod
4. look for stable ground (rocks) for tripod
5. temperature different cause Water vapor inside len

safety first ……..
