Yeah?! Thanks! This was done with the jpgs from the camera, I've got darktable crunching out the same set with some edits so hopefully some brighter stars.

Animality

Hi!
Alright..I may have forgotten to post yesterday…sorry about that :D. So today I’ll go with animal theme. The first one is a cat (as you might have guessed by it’s facial expression) and the second one is something a bit more unpleasant. My titles for these photos are pretty straightforward: “Cat Stare” and “What makes you tick”...try to assign them correctly ;)

That’s all folks

4 raw pictures handheld with philopod and pitch variation. Image processing with Rawtherapee, imagemagick, GIMP and Neat Image. Stitched with Hugin. No one single error corrected after stitching (which doesn't mean they doesn't exist :) the scene is good in hiding them.

ISO 6400 ISO 6400, F4, 1/40s. I have to improve my shooting technique. In order not to lose details of brighter areas I'm doing too dark pictures and when I increase the bright the noise gets even stronger. That's why I tried to use 3 tools to remove it even after having already treated it in rawtherapee.

I want to test noise removal by making many pictures of the same scene, then Enfuse them, but that is somehow hard using a philopod :)

Hello, here I am again. This time trying to repeat in a funny way an iconic Vogue image by Richard Burbridge. A very fast project we did in 30 mins in my room using stuff found around. And here is the outcome.
 As always RAW images processed in #Darktable, retouch made in #GIMP 2.9 development version.

Hi +Patrick David if you would zoom in, you should be presented with more  skin detail :) at least that is how it is on my computer and G+ But I definitely need to work on the balance on how much skin cleaning makes down-scaled images appear smooth. The original image by Richard as I assume had even smoother skin, but the copy I had was low resolution so can;t really tell. But it was a fun exercise and probably that could be an interesting challenge contest with lots of inspiring results. :)

Hello all, I tried to start Hugin Panorama and got this. I've got no idea what it means but I'll try a reboot and see if it works. Running Mint 17.1. 
UPDATE:  A reboot didn't help.

Never mind, I see the mismatch now. Mint 17.1 is still on Ubuntu 14.04 so I had to remove the same PPA. Thanks.

Midnight Train
Given enough time and persistence, we may find light, even in the dark.

This is a long exposure (152 seconds) over Canyon Lake in the Four Peaks wilderness in Arizona... I remember this night vividly. We were just coming back from Dinner at Jason's Deli, December 26, 2012. Another great night with a great family and loved one I miss so much. The full moon had risen, and the clouds above promised to be playfully dancing in the sky for a few more hours.

I jumped out of the car, grabbed my camera gear and raced off into the wilderness for the night. I spent hours playing in the night air, watching as the clouds caressed the sky in passing... reveling in the knowledge that, as rough as the water before me may be... time averages out most things, leaving something to reflect upon.

I dug many years back to find this photo. It has always been one on my mind, I reflect on this photo and that night often, and I haven't shared it with many. This was a better time. A better place. A time where I had my feet on the ground, and I was passionate about... just about everything.

Time to stop repeating so many of the recent mistakes, and start walking down different roads. The sunrise is coming.

Technical Details
Canon 5D Mk III
EF 24-105mm f/4L IS at 24mm
F/5 for 152" at ISO 100
Raw processed in +digiKam on Linux, with final processing in +GIMP  with +G'MIC .

Thanks for the reshare, +Patrick David .  I was actually going to share it here... but for some reason, the "communities list" wasn't showing up in my drop down list.

Telebirding

Another day, another two-barrel shot.

In the past weeks, I got some longer focal lengths to shoot with. I have no results yet to show for the biggest lens in my collection yet, but the 135 mm f/2.8 has proven reeeally useful. On APS-C it’s equal to about 200mm, so it can actually get a little tighter than I’d like, bus as a handy telephoto lens, this thing is awesome. The photos below are quite similar, so I thought it can’t hurt to put them together. I titled these “Fine Dining” and “Ready for Takeoff”.

Have a great day!
Stanley

Rotten to the Core

Oh hi!
Has this ever happened to you? “It’s a deep night, somewhere in the middle of the forest, no light around apart from the moon and stars. And suddenly, you see a light source on the ground. You move closer ot examine it and find out it’s a decomposing bit of wood!”
That’s pretty much to gist of what happened to us. So I got asked If I was able to photograph a light source this weak (let’s face it…it’s barely visible unless it’s pitch dark). I took my 12 mm f/2.0 lens and what do you know…it worked! I had to keep the exposures pretty long, but I didn’t care…the shots were worth it. I then took out a speedlite in hope to capture a bit of a background with the glowing wood too. I have used the weakest output possible and bounced it off the other wall of the shed and it created the overal fill pretty nicely…but I’d still like it even weaker. I then had to rely on a long exposure to make the glow strong enough to have something to work with in PP. (TBH, in reality, the colour wasn’t so pronounced, but this is still dialed down from what the camera captured – that was crazy radioactive green!)

Thanks. The exposures were usually about 40 seconds. During those, the glow got fairly bright and I could use the lowest power on my flash to fill the background a bit without disturbing the glow.
This photo is a composition of several images and Gimp tends to strip metadata when transfering from tiff to jpg...sorry bout that ;)

I've switched to Ubuntu Studio and am trying to install Macrofusion. When I install I get:
The following packages have unmet dependencies:
 macrofusion : Depends: python3-imaging but it is not installable

I've been Googling this for about an hour and I can't tell if I have v2.7 or 3.4 installed... or both... or neither. Studio is built on 15.04 so I would think it has the latest python...

I was out with a group last night trying to shoot the Milky Way. The rule of thumb for crop sensors is 400/focal length = exposure time. My exposure time was 25 seconds. I used my Nikon D7000 and Tokina 11-16 f/2.8 wide open and bumped the exposure time to 30 seconds which gave me more of the Milky Way. That left my ISO at 1250 which I don't consider high but in this case I find the noise to be waaayy too much. 
What are your opinions on the noise in this shot? Too much or am I too critical? Noise reduction seems to involve a lot of magic to get it right and so far I haven't mastered the magic. What's your noise reduction magic?

+David LaCivita well those Plugins are 8bf files, so you would need PSPI and here in Germany you can find it i.e. at Heise downloads (http://www.heise.de/download/pspi-1167371.html) it looks like the original place is gone but it wont work with a 64bit environment well at least I can't get it to work

Two rows of three, camera turned vertical.  The center nave had to be easily 60-70 feet high.
