Clouds




Recorded 2012 - 07 - 31



There was a cloudburst while i was just about to capture some images of the sun.

It almost passed over the house.


Here's the sequence after it had passed by:
Recorded with a Canon EOS 500D, EF-S 10-22mm @ 19mm, 1/350th shutter, f/19, ISO 100.
4 seconds between each frame for 21 minutes.

Solved flicker issue. It's due to the aperature opening up full then goes down to the selected F number for each shot.
It's reported to be 94% accurate which you won't notice when taking random shots but clearly shows up in sequential shots.
The trick is to first to set your exposure, aperature, iso and such and then hold down the "depth of field" button.
This will engage the aperature to its selected F number. Now while holding down that button, click the lens release button and slight twist it so the camera loses contact.
What you have now done is locking the aperature so it stays the same throughout your sequence. You'll lose EXIF data for the lens though.

Had to try out that trick right away and it resulted in these 3 shots:

Sequence A - 4 seconds between each frame. EF-S 18-55mm IS, 1/250th shutter, f/11, ISO 100.

This is a reprocessing of my RAW files from 2011 - 07 - 11.
Redid all the RAW files with DxO Optics Pro 6. I also ran a deflicker filter in VirtualDub.

Recorded this sequence with a Canon EOS 500D, EF-S 18-55mm.
Used a TC-80N3 to capture images every 2 seconds for 22 minutes.


The images were captured in RAW and converted with DxO Optics Pro.
They were then assembled, resized and applied a deflicker filter in VirtualDub to reduce flickering.

Sequence - 272 frames - 1/1500 shutter, f/5.6, ISO100, 55mm focal length. Recording started 19:09 local time.

Here's a 100% crop of the frame with the pigeon flying past. I have no idea what it is doing.

Recorded this sequence with a Canon EOS 500D, EF-S 10-22mm.
Used a TC-80N3 to capture images every 2 seconds for 1 hour and 14 minutes.


The images were captured in RAW and converted with DxO Optics Pro where i changed the light metering from 'Evaluative Metering' to 'Center weighted-average' in order to reduce flickering.
They were then assembled, resized and applied a deflicker filter in VirtualDub to further reduce flickering.

Sequence - 895 frames - 1/3000 shutter, f/3.5, ISO100, 12mm focal length. Recording started 16:09 local time.

Recorded these two sequences with a Canon EOS 500D, EF-S 10-22mm.
Used a TC-80N3 to capture images every 2 seconds.

I think these clouds formed and stayed in place due to a local lake nearby.
The direction fits pretty well to where the lake should be in relation to the camera.

The images were captured in RAW and converted with the Canon software into JPGs.
They were then assembled, cropped and had a simple levels filter applied in VirtualDub.

Sequence A - 896 frames - 1/500 shutter, f/11, ISO100, 17mm focal length. Ran out of space on my 16GB flashcard.

Sequence B - 473 frames - 1/750 shutter, f/11, ISO100, 22mm focal length. Used my 8GB flashcard until that too ran out of space.

These clouds started to appear while i was shooting the sun. So i grabbed my DSLR to shoot a time lapse.
5 seconds between frames, 749 total frames.

Link 11mb quicktime at 594 x 396.


Noticed something peculiar as one of the planes passed by. It was as if it created a turbulent flow behind it. But that kind of fast movement at that height? Think it might just be a cooincidence.

100 frames cut and cropped.

Captured this time lapse of clouds. However i had forgotten to switch it to manual, it was set to shutter priority to it switched between 1/2000 and 1/4000 shutter. That's where the flickering is coming from.
Used a Canon EOS 500D, EF-S 10-22mm @ 10mm f/4 and ISO100.
