Post Processing: A Guide for Nature Photographers

Post Processing: A Guide for Nature Photographers

An E-Book from Glenn Bartley
Our friend Glenn Bartley, who wrote our review of the EF 600mm f/4L IS II here at Canon Rumors is offering our readers his wonderfully indepth, but easily understood post processing e-book at a discounted price of $20 (Save $5).

Glenn is in the top 1% of nature, and especially bird photographers that I know of on the planet. Be sure to check out his work to see some wonderful images.

I personally found the e-book easy to understand, but has corrected a lot of my bad habits. I’ve learned a ton about highlight recovery and dealing with curves to really get the subject to pop. Everything in the book is easily accessible to people like me that don’t really love the art of post processing, but certainly love great results. Gaining an understanding of how things work, will make you more efficient with your post processing in the future, which will give you more time to shoot.

What’s in the book?
This E-book is designed to share the strategies and techniques that I have developed over the years to improve and simplify Post Processing. In my own processing I use primarily two software platforms (Breezebrowser and Adobe Photoshop). As such, this book is aimed primarily at photographers hoping to learn to use Adobe Photoshop. However, many of the skills and techniques in this book could also be transferable to other software platforms.

The chapters of this book are organized in a logical way to work through the following steps:

  • Creating a logical and efficient file management system
  • Culling images effectively and selecting your best work
  • Converting RAW files
  • Processing images in Adobe Photoshop (many skills transferable to Adobe Lightroom)

This guide is for you if you want to:

  • Spend less time at the computer
  • Learn to use Adobe Photoshop
  • Streamline your processing workflow
  • Take your best images and take them to a whole new level
  • Display your images to family and friends

Included with this ebook are:

  • Downloadable Photoshop Actions designed to save you time.
  • Sample Images to work on (cloning, layer mask, noise reduction)
  • Links to over 1 hour of online video tutorials

New Technology Coming to Cinema EOS

New Technology Coming to Cinema EOS

From the interview with Mr Onda
Reading a bit between the lines during the interview with Dan Chung and Mr Onda, it appears a few new things are coming to the Cinema EOS line and probably to EOS DSLRs as well.

The first being CFast 2.0, a version of Compact Flash announced back in 2008. SanDisk currently makes CFast cards that are capable of writing at 350MB/s. These cards will be needed to record 4K RAW video. It sounds like Canon will be moving towards CFast in their next Cinema EOS cameras, and perhaps DSLRs as well.

Secondly, it seems there’s a possibility of a full frame Cinema EOS camcorder coming down the pipeline.  While you can currently get full frame 4K recording (16:9 crop from the full frame sensor) with the EOS-1D C, the C100, C300 and C500 are Super35 sensor cameras.



From InterBEE: Interview With the Head of Cinema EOS

Newsshooter talks C100 Dual Pixel CMOS AF with Canon’s Mr Onda
Dan Cheung sits down with the head of Canon’s Cinema EOS product line to talk about the C100 dual pixel CMOS AF upgrade that was recently announced.

Mr Onda clarifies that the update to the Cinema EOS C100 is firmware and a “service adjustment”, as it and the EOS C300 already have Dual Pixel CMOS AF capabilities at the hardware level.

They also talk about lenses and RAW video and why they think the “lower range” cameras don’t need the RAW video capabilities that the C500 has. It’s also fun to watch Mr Onda discuss Magic Lantern and the actual hardware capabilities of their cameras like the EOS 5D Mark III.

An interesting point is Mr Onda says they plan to introduce STM technology into “L” lenses. Although he mentions that developing an L lens takes a lot longer to do than the current STM lenses.

The image sensors of digital SLR cameras continue to offer higher and higher resolution, and photographers are looking for high-performance lenses that leverage these sensors’ full power. In the case of zoom lenses as well, which are a dependable go-to in a wide variety of photographic conditions, photographers want convenience combined with exceptional optical performance. The new SIGMA 24-105mm F4 DG OS HSM zoom lens more than fulfills these requirements, offering exceptionally stable high resolution from wide-angle to medium telephoto photography.

While featuring a large-aperture 82mm filter size, this lens minimizes optical aberrations and avoids reduced peripheral brightness, an issue that tends to affect lenses with similar specifications. Each lens is checked with Sigma’s proprietary A1 MTF (modulation transfer function) measuring system to ensure it offers exceptional quality for the high-megapixel era. Try this new high-performance zoom for yourself, and experience Sigma’s uncompromising pursuit of high resolution.

The full realization of the Art product concept for you to hold in your own hands and appreciate with your own eyes.

With unsurpassed expressive performance, these lenses reach the high standards demanded by photographers with an artistic, creative inclination. Along with landscapes, portraits, still-life, close-up and casual snaps, they’re perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. Hold it in your own hands and appreciate it with your own eyes.

Review – Canon EF 17-40mm f/4L

Review – Canon EF 17-40mm f/4L

New Review
Justin has completed his review of the Canon EF 17-40mm f/4L ultra wide angle zoom lens from Canon. For a lot of people, this is their first wide angle zoom and becomes a workhorse.

I know one landscape/nature photographer who uses this lens extensively and it’s used for about 75% of images that he sells, and he sells a lot! This is a great lens for publishing and using all the time. I have a hard time recommending the 16-35 f/2.8L II to anyone other than an event photographer. The EF 17-40mm f/4L is a workhorse that is reliable and doesn’t cost a whole heck of a lot.

Justin likes it a bit less than I do, but the review is pretty positive.

More talk of the biggest of the whites
We’re told that an announcement for a new EF 800 f/5.6L IS II could come at any time, as the update is “ready to go”.

We’ll see if Canon can price it higher than Nikon’s version!



More Medium Format Talk [CR1]

More Medium Format Talk [CR1]

This and that
A few people have written in to confirm that Canon is exploring the possibilities of entering into the medium format segment.

We’re told nothing is imminent, but things could change quickly in the next few months. How long this has been going on is unknown, but it does sound like it’s a real possibility.

No one has confirmed or denied that Phase One is the medium format company in question.

Over at NL, they received an outright dismissal to the concept. However, a second source said Canon is going to be all in, and will announce in a big way some time in 2014.



Canon Testing a 75+ Megapixel EOS-1 Body? [CR1]

Canon Testing a 75+ Megapixel EOS-1 Body? [CR1]

The big megapixel camera gets bigger!
Photography Bay is reporting that a good source of theirs has told them that Canon is actively testing a 75+MP EOS-1 DSLR camera body.

I don’t find anything surprising in the megapixel count, as Canon has announced enormous megapixel sensors in the past. However, this is the first I’ve heard of an actual product using image sensors with this much resolution.

Previous rumors have placed the “big megapixel” camera from Canon in the 40-50mp range.

We do expect such a camera to make its way to us sometime in 2014.

EOS 5D Mark III w/24-70 f/4L IS Kit Coming Soon

EOS 5D Mark III w/24-70 f/4L IS Kit Coming Soon

Is the EF 24-105 f/4L IS Going Away?
The EF 24-70 f/4L IS will soon be kitted with the EOS 5D Mark III. I’m also hoping we’ll see it with the EOS 6D as well.

The release date for the new kit(s) is June 13, 2013.

As of writing this, we have no pricing. Expect to see some “white box” discounts on the EF 24-70 f/4L IS soon.

I haven’t heard anything in regards to the EF 24-105 f/4L IS getting discontinued, so I’d expect to see that lens in kits for some time to come.

EF 24-70 f/4L IS $1199
