Testing Out a Rosco Gel Kit for Creative and Colorful Photographic Lighting

roscokit

I received a Rosco Gel kit a week ago, and after a few tests I can say I really love using all the awesome colors for my photography.

The kit includes 20 individual 30x48cm square sheets for color corrections (e.g. CTO, CTB, ND) and a range of different colors, all of them contained in a protected and resealable packaging.

Stress Testing SD Cards to See How Their Real Write Speeds Stack Up

The popular YouTube tech channel LinusTechTips recently did an SD card showdown to see how the actual performance of the cards compares to what’s written on the labels. One of the things they did was a Canon 6D test, the results of which can be seen in the graphic above (here’s a larger version).

MTF Testing the Canon 11-24mm f/4L, the World’s Widest Full Frame Rectilinear Lens

Editor’s note: If you’re unfamiliar with how to interpret MTF charts, you can find primers here and here.

I’ll be honest. I’m pretty excited about the Canon 11-24mm f/4 L lens. I love shooting ultra-wide and the chance to shoot this wide with a rectilinear lens on a full-frame camera has me pretty excited. But I’m also very aware of how near-impossibly difficult designing a lens this wide would be, so my expectations were tempered a bit.

There’s a reason I’ll often stitch together a couple of 24mm shots for a landscape rather than take one 16mm shot. OK, there are several reasons, but image quality is high among them.

Testing the Yongnuo 50mm f/1.8 with Nightscape Photography

Yongnuo 50mm Image 1

February has brought back the galactic core of the Milky Way into the sky. It is now rising in the east just before sunrise. Each week it will rise a little bit earlier in the night.

I have a trip planned for this spring and have been thinking about some of the shots I want to do. One of them is one where I think a lens longer than the 24mm might be useful to really bring some mountains and the Milky Way together.

Nikon’s newly-announced D750 has impressed those who have managed to get their hands on it thus far, but to properly put it through its paces, DxOMark ran it through its trusted sensor tests.

As expected, it came out with quite high marks, putting it in 8th place on DxOMark’s overall rankings and making it the 6th Nikon camera to make it into the top 10.

Video: Torture Testing the Front Element of Canon’s ‘Thrifty Fifty’ 50mm f/1.8 II

Photographers commonly place UV filters on the front of their camera lenses in order to protect the glass front element. Aside from preventing dust buildup, the filter also takes the brunt of any impact seen by the front of the lens. If you have to have some glass shatter, you’d rather it be a relatively cheap filter compared to an entire lens, right?

But how easy is it to damage or destroy the front element of a lens? Photographer Richard Choi had the opportunity to find out a few years ago when he found a bricked lens on his hands.

“Commerce makes progress. Fortune passes everywhere.” – Frank Herbert

A few years ago I was accused of being a Sigma hater. (For the record, I did hate their quality control and so-called repair service at that time, and I didn’t hesitate to say so.) For the third or fourth time in the last year, I’m about to be accused of being a Sigma fanboy.

Stabilized Canon 24-70mm f/2.8L On the Way, But May Be A Year Away

canon2470mmf28is

After the Canon 24-70mm f/2.8L Mark II was announced at the beginning of this year, many photographers were disappointed that it didn’t include Image Stabilization. When October rolled around, there were new rumors that Canon had an IS version of the 24-70mm up its sleeve. The company did, but it wasn’t what people were expecting. When the new IS lens was unveiled in November, it was an f/4 lens rather than an f/2.8.

If you’re one of the many people who wanted both the convenience of having IS and the benefits of having f/2.8, here’s some good news: there is indeed a 24-70mm f/2.8 IS on the way.
