VR ready tour with 4 panoramas at the Buenos Aires Zoo.

All with philopod. I really didn't like 2 images that were shot too originally too dark, but as a trip memory it's ok. All made with philopod, 5Dm3, Canon 8-15mm @~ 12mm. Two stitched without post edition and other 2 with some GIMP post edition. In one I had to cover a black area that the pictures didn't cover (my fault) and in the other I've had to build a missing shadow part.

Softwares used: Rawtherapee, Hugin, Enblend, Panotools::Script, imagemagick, GIMP, krpano, Linux, krpano.

A nice basic introduction to using RGB color curves, and how they operate.  Might be helpful if you haven't really had a chance to play with them yet... :)
 
An oldie but a goodie: a simple look at color curves.  For those who may not have played with them much before, a gentle introduction and example.

8 immersive panoramas, 2 of them aerial, 1 with a pole and 5 with philopod at Arpoador, Rio de Janeiro, Brazil. A well known natural touristic place in this city, the first place where a bikini have been worn in Brazil.

Mostly made with opensource souftware: Rawtherapee, Hugin, GIMP, Panotools::Script, imagemagick, enblend+enfuse, all on Linux.

If you have a VR glass you can use it!

Surely it took some time, but not planned at all. As it's a place near my house, I go there sometimes. When I realized, I had a lot of material, so I put them together :)

Solitaire and the Galaxy

Heya!
We’ve gone through another short era of inactivity. But we have shot tons of new photos so there should be quite a surplus in the upcoming days/weeks ;).
After quite a while, I’ve finally gotten the chance to test the full potential of my first non-kit lens, the Samyang 12 mm f/2.0 NCS CS. I bought this lens after reading a rather inspiring article about astrophotography somewhere in the depths of the internet. That being said, you can expect heap a nighttime photos in the days to come! I’ve used this lens so far for interior shots, some architecture and a couple of landscapes, but none of that competes with nightscapes with this thing!
And now to the photo below. I usually don’t share much EXIF data (mainly because GIMP has rather hard time keeping them in the file :D), but this one deserves it. The lens has superb results even wide open, so this was shot at F/2.0, somewhere between 15 and 25 seconds exposure and ISO of just 800! I still had to deal a lot with the moonlight filling the sky (it was about two days past the full moon), so the noise creeped in anyway, but thanks to the team developing RawTherapee, the wavelets tool killed the noise quite nicely. Anyway, here is the result. I believe I will be driven to writing a short review for this lens soon, as it deserves it!
Also, I recommend viewing the photo in full resolution here: http://bit.ly/1CHlBE8

Have a great day
Stanley

I'm using Macrofusion to blend 6 exposures of the Fire Dept. Museum here in Brockton. On the right is a screen shot of the preview and on the left is the final output. What the heck happened?

From the creator of the +PhotoFlow Editor, +Carmelo DrRaw brings us a great tutorial on using a combination of +Hugin and PhotoFlow to not only stitch together a panorama image, but to also expand the dynamic range in the scene through masks and multiple exposures (there's even a little Enfuse thrown into the mix!).

Come check it out!

Another night out with the Greater Boston Night Photographers. This time we thought it would be fun to strain our necks...

All photos shot with my Nikon D7000 and Tokina 11-16mm f/2.8. Processed in +darktable, a free and open source RAW development application.

I  managed to wrangle photographer +Riley Brandt  to sit down and answer a few questions about his photography and his recently released Open Source Photography Course!

Also, he has graciously given us two copies of his course to give away to readers.  Check out the blog post about it here (https://pixls.us/blog/2015/07/the-open-source-photography-course/).  Thank you Riley! :D

Help spread the word!  You might just win a free copy of the course!

A nice post from the +darktable team about supporting Windows (and why it's not going to happen soon unless someone steps up to the plate to build and support it).

That was a nicely reasoned statement. It made it very clear why there is no Windows port, without resorting to any major character assassination.

All edits made in +darktable. The only daylight image was a 3 exposure blend using Macrofusion. 
 
My first time shooting fireworks and in America's Home Town, Plymouth, MA.

There wasn't much of a breeze so the smoke lingered but I think I managed it in post processing.

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 ;)
