+Frank Doorhof​ is a rather well known photographer and tutor.

This is the pilot episode for a live workshop series he is putting together.

Plus, I believe it does make a great example of what is possible with Google hangouts.

I suggest you check it out ;)

Today we did a test broadcast in our new project called "Digital Classroom"

And I think we can say it was a succes.
We didn't announce the broadcast as public as we normally do because there was too much that "could" go wrong :D

But don't worry, we recorded it for you.
You can see it as 3 hour free instructional video all shot live with your questions thrown in.

This episode was made possible by BenQ and Rogue and of course our friends at Elinchrom.

Enjoy the first episode via our YouTube channel on https://youtu.be/GE2UKkORaVY

Sunny Mountains

Another photo taken in the mountains of Greece.

Had some great time shooting  landscapes this summer. Can't wait to find the time to get out there again!

Good morning, dear Followers!

WARNING: Do NOT follow this +Sauber F1 Team collection if you prefer not to see our instant updates during sessions and races! If so, make sure to unfollow this #collection (as you'll be following it automatically until you take action).

We'll be posting current news and the results from the track, mostly replicating our tweets.

And now it's time to post our amazing photos from Barcelona. But you won't find those in this collection ;-)

Cheers, +Sauber F1 Team

Do you people think there is a point in having a collection for posts in a language other than English ie my native tongue???

Would it help others to "get rid" of posts they can not read and/or relate to???

NASA being awesome on May the Fourth!

Give me a smile

The obligatory first photo with the street lights in the background, while learning the ropes of my new 85mm lens.

+Mike Browne​ moving to a new profile, here on Google+

In case you were already following him, make sure to make the jump.

In case you weren't, here is your chance to have a great guy, tutor and photographer in your circles :)

 
I'm moving this Google Plus "Profile" to a new "Page" because as a profile, I'm limited as to what I can do for you. Over the next few weeks and months everything will move over to the new page and this one will be used less and less. I'll keep you posted and ask everyone to please move over when it's ready. Thank you all for being brilliant. It's because of you I now have more followers than I'm allowed as a mere "Profile" and that's one reason for changing. There'll be a video announcement on Youtube soon...

Crop factor applies to more things than you probably thought it did

Crop factor is something that people using the smaller, cheaper APS-C cameras, have learnt to live with, over the years. It is something that does not really matter once you slap a lens on your body and start shooting, but should probably be factored in, when making purchase decisions. 

For the most part, if you thought about getting  a 50mm lens for your cropped camera body, you did two things:

1. Repeat three times religiously, “50mm is 50mm is 50mm”

2. Multiplied the focal length of the lens by the crop factor of your sensor to calculate the equivalent focal length, in order  to estimate the field of view you would actually get from the lens.

It turns out though that most of us have been doing half our homework, all this time. The crop factor applies to even more things and makes the “equivalence” concept affect more than just the FOV. 

It was almost a year ago, when I first stumbled upon +Tony Northrup 's video, explaining why aperture and ISO, should also fall under the equivalence umbrella. In a total of 4 (or maybe 5 videos), Tony went on to explain his logic and the facts behind these claims. 

Upon further research, because I am geeky like that, I discovered another, well trusted source, describing in detail, the exact same thing. +dpreview 's article, published back in July of 2014, stated that aperture and ISO (well, ISO is a bit more complex, but you need to read the article….) should be treated the same way we have been treating focal length, when considering the crop factor of a sensor. 

Let’s make sure that there are no misconceptions here. The actual physical properties of a lens are what they are and can not change, regardless of the camera body / sensor size combo we mount them on. 

That being said, the crop factor, does affect the final image, in terms of FOV, depth of field, and noise (if we assume the same sensor tech is being used!). So, just like you would multiply the focal length by the crop factor, to get the equivalent focal length, you would have to perform similar calculations to get the equivalent F stop and equivalent ISO.

Even if all this is too technical for your liking and all you care about is making images (which is what you should only care about really….), take this one thing with you. Do not let any marketing material convince you that a 50mm F 1.8 lens, behaves like a F 1.8 on two different systems!

If you fancy getting all the details for this you can either check Tony’s videos here:

#photography #geek
Equivalence, at its most simple, is a way of comparing different formats (sensor sizes) on a common basis. Sounds straightforward enough, but the concept is still somewhat controversial and not always clearly understood. We thought it was about time we explained - and demonstrated - what equivalence means and what it doesn't. Learn more

+Jamie Hamel-Smith​​ just like you said, when you are making a photo, none of this should come into the equation.

Frame your shot, set your exposure and hit the shutter release.

The only time any of this matters, is when you desire to understand how and why things work under the hood and when a lens manufacturer tries to convince you that their 150mm f2.8 lens for a crop factor system, is the same as having a 300mm f2.8, for a third of the price, size and weight.

Glad you enjoyed reading the links :)

This is simply too good not to share!!!
Lars Fosdal originally shared to Weird Wide World:
Owls, known around the world as symbol of wisdom and wizardly postal services, have never looked as cute as this! Photographed by Thai photographer Sasi Smith, these owls show all of their splendor.

Introduction
Here is what you need to know about me:

  • Photography has been an emerging passion for me, over the past few years. I enjoy the shooting as well as the post processing part of the art. If you are into Lightroom, consider checking out my Page (links below)
  • Technology. I need it. Every day. Period. 
  • A long time F1 fan. For me, the king of sports, hands down!
