Yongnuo YN622C TTL Flash Trigger Video Review by Phil Steele

01 August 2013

I've been thinking to replace my Cactus V4 wireless flash trigger from a while, as they are not bad, they work most of the times, but not all the times, especially when you have to fire 2/3 flashes at the same time. So I'm starting to take a look around and see what other options I have, and while in the past I wasn't really a big fan of Yongnuo, after I bought a Yongnuo flash few months ago I drastically changed my opinion about this brand, and their new flash triggers seem to be pretty good, still not au-pair with brands like PocketWizard, but you can get 4 transceiver for the price of one PockerWizard. But are they good? Dunno, but according to this video review by Phil Steele it sounds like a good product, not perfect, but still good.

How To Develop a Raw File by Chris Knight

04 July 2013

I just stole this video from Fstoppers, where Chris Knight shows one way to developer RAW files in Lightroom 5 and to get as much as possible of dynamic range, and that's one of the reason you should always shoot in RAW, as this format keeps alll the information the sensor of your camera can catch, information that would be lost if you shoot in JPEG.
Bear in mind that this is one method, not THE method.

What\'s the difference between the F Stop and the T Stop number?

30 June 2013

A few weeks ago I was looking for the prices for the Samyang 24mm f/1.4 on Amazon, an affordable wide prime lens, when I noticed that just underneath tha lens, it was listed the following lens, the Samyang 24mm T1.5 lens, which is essentially the same lens but for videographers, with a better focus ring. But while it was pretty clear that the T1.5 was related to the max aperture for the lens, I didn't really understand why it was using a weird value (1.5) and why the T and not the usual "f".
The answer is simple: while the f number indicates area of the aperture of the blades, the T value indicates the amount of light that ends on the sensor of our cameras, and because light has to pass through the different pieces of glass in our lens (I didn't want to say lenses of a lens, it sounds weird to me), which reflect and/or absorb light, you will never get the 100% of light transmission, and the T number indicates the real amount of light that ends on the sensor. But as I'm terrible to explain how things works, and I doubt I will ever present an episode of MythBusters, maybe it's better if you just watch the video above, where Matt Granger explains, way better than me, what's the difference between the F Stop and the T Stop number.

How To Sharpen in Photoshop

30 May 2013

In this very interesting video, SLRLounge contributor Lauri Laukkanen is going to show us three different techniques to increase the sharpness of an image in Photoshop.
Personally I prefer the first one (and I guess is the same for Lauri), but I use slightly different settings, like I stay between 1 and 2 in the High Pass Filter, and then I used Overlay, but at the end the result is the same.
