Written by Ken Sklute and Dave HenryRead the entire article on the Canon Digital Learning Center. Click here for more CDLC articles with tips on photographing the upcoming eclipse.Since the earliest days of photography, scientists worked at making a successful image of the corona during a total solar eclipse. The first correctly exposed photograph of the corona during a total solar eclipse was made on July 28, 1851 by daguerreotypist Johann Berkowski at the Royal Prussian Observatory at Königsberg (now Kaliningrad, in Russia). The exposure was 84 seconds during maximum eclipse. Numerous attempts were made earlier, but Berkowski’s image was the first correctly exposed image.
A cropped and enhanced version of the original Berkowski daguerreotype of 1851 clearly shows that not only did Johann Berkowski correctly expose his 84 second daguerreotype, he was the first to document the solar flares, known as prominences, emanating from the sun's surface. This daguerreotype became the benchmark for later photographic attempts.
Throughout the remainder of the nineteenth century and on to today, photography has played a significant role in science. Correct exposure though, makes the photograph useful.

Several years ago when I was first exploring the wonderful world of off-camera flash, radio triggering options were very limited with rudimentary capabilities. It's amazing how much the radio triggering market has changed since then.
Now, in addition to the basic triggers of ye olden days, we have radio triggers that can remotely adjust the power levels of compatible flashes or even adjust power levels automatically via TTL technology. In other words, there has never been a better time to explore what radio-triggered off-camera flashes can do for your photography.
If your current flashes support radio triggering – like the Canon Speedlite 600EX II-RT – then you don't need anything else. However, if your flashes or studio strobes don't feature radio triggering, or if you need to incorporate non-radio enabled flashes into your radio flash setup, then radio flash triggers will be worth looking into. And on that note, there are a few things to consider when arriving at your preferred choice of radio trigger.
Type of Connection
First, it's important to understand how these radio triggers connect to our shoe mount flashes (and possibly studio strobes). Radio triggers primarily connect to compatible flashes in one of two ways, either by a cable connection or via a hot shoe (and most of those triggers featuring a hot shoe can also trigger via a cable connection).
The most common type of sync port found on shoe-mount flashes is a PC terminal. These sync ports have been an industry standard for decades, but... they are not my personal favorite type of connection. First of all, PC cables are not very robust (easily damaged) and they sometimes disconnect from the socket when a flash is handled with the cord attached (though locking PC compatible ports mitigate this issue).
A far simpler solution, however, for triggering a shoe-mount flash is to use the flash's mounting foot. Many newer radio triggers feature a built-in hot shoe that your off-camera shoe-mount flash simply slides into. In my opinion, this is the best triggering solution as it eliminates the need for cables which can easily be lost, damaged or simply not long enough (or inconveniently too long) for a specific application.
Transmitter/Receiver or Transceiver
In addition to the type of connection a radio trigger features, it's important to understand whether a specific triggering system is built on separate transmitters and receivers or if a single device can act as both, i.e. is a transceiver. In regards to the separate transmitter/receiver systems (such as Vello FreeWave LR, Radiopopper Nano), a significant pitfall is that is that a single transmitter failure (without a spare transmitter to fall back on) will render all of your receivers completely useless. Alternately, a single device failure in a transceiver setup (such as the PocketWizard Plus/FlexTT* or Cactus V6) means that you only lose the ability to trigger one flash, not the entire group, as any of the devices can act as a transmitter.
In some cases, a company may even produce radio receivers that are completely compatible with camera brand master flashes or transmitters, thereby allowing the use of older (non radio enabled) flashes to be used in an otherwise radio-enabled setup.
Range
One of the primary advantages of radio triggering technology is that it eliminates the line-of-sight requirements for trigging off-camera flashes as well as boosting the range even if line-of-sight positioning of flashes is possible.
For instance, Canon Speedlite's optical flash triggering system has an advertised range of 32.8 ft (10m) outdoors and 49.2 ft (15m) indoors. And technically speaking, line-of-sight isn't always required indoors if surfaces are available for the master flash's transmission to bounce off of in order to communicate with slave flashes.
Now contrast the previously mentioned optical triggering range with that of typical radio triggers advertising anywhere from 300 ft (91.4m) to 1,600 ft (487.68m).
Suffice it to say, most photographers will never need to trigger an off-camera flash from 300+ ft away, but... it's nice to know that your flash will fire when you need to position it in a location that exceeds the capabilities of optical triggering.
Brand Longevity and Backward Compatibility
Another thing to consider when shopping for radio triggers is the likelihood of the brand remaining in the radio triggering market for the foreseeable future and whether or not they have displayed a commitment to backwards compatibility with previous generation devices. One example, PocketWizard, has been producing flash triggers for more than 15 years with newly released products always being backwards compatible in terms of radio frequency.
Basic / Advanced Triggers
In regards to radio flash triggers, there are basic triggers and advanced triggers. Basic triggers transmit/receive only one highly relevant piece of information – FIRE! Because they are relatively easy to design and manufacture, there are a wide range of companies that produce these very-easy-on-the-budget triggers. While most of the triggers will work as intended most of the time, you may experience or occasional misfires and you'll likely forego high build quality with flash triggers at the lowest tier pricing level. Examples of basic triggers include the PocketWizard PlusX, Radiopopper Nano, and Yongnuo RF-603C.
On the other end of the spectrum, advanced triggers provide a myriad of features that make them more versatile and/or more convenient for those working in a professional (or semi-professional) atmosphere. Some advanced triggers are capable of:
Not all advanced triggers feature all of the capabilities listed above, but most offer at least some of them. The extra features of advanced triggers compared to basic triggers come at a higher cost, of course, but the price differential translates to significantly increased convenience and versatility. Examples of advanced flash triggers include the PocketWizard FlexTT*, Phottix Laso, Cactus V6 and Yongnuo YNE3-RX .
Which radio trigger is right for you?
If you're just exploring off-camera flash for the first time, it's probably a good idea to invest in a set of basic triggers. Why? Because all of the extra features afforded by advanced triggers can complicate the off-camera flash learning process. Basic triggers require manual flash power adjustments and therefore simplify the "cause and effect" learning process. Once basic lighting principles have been conquered, the value of the advanced triggers' full feature set can be fully appreciated.
Then again, nearly all advanced radio triggers can replicate the functionality of basic triggers. So if you're ready to jump down the rabbit hole, but still inexperienced with off-camera flash, you can invest in an advanced flash trigger system and use them as basic triggers until you're ready to explore the augmented feature set.

Performance, Quality & Comfort, Redefined
Upper Saddle River, N.J. (June 13, 2017) – Manfrotto, a leading global innovator and manufacturer of premium photo, video and lighting support products and accessories, has launched the new Pro Light Bumblebee bags - perfect for professional and amateur photographers and videographers who work outdoors and want a reliable carrying solution. With this collection, users can stay comfortable in the harshest of conditions despite high temperatures, extreme cold or high humidity.
The new Pro Light Bumblebee family is an exceptional assortment of high-performance camera backpacks and messenger bags which perfectly embody Manfrotto’s Italian heritage. This family introduces Manfrotto’s unique-to-the-market breathable harness system that greatly reduces photography gear fatigue, allowing image makers to cover more ground and locate the best spots for the perfect shots.
Inside, the bags’ innovative designs safeguard the latest professional equipment options. The renowned Camera Protection System (CPS) dividers take extra care of camera bodies and lenses. They are fully adjustable and built to distribute weight evenly and avoid tension to the body.
The new Manfrotto Bumblebee backpacks are designed to take stress and heat off the shoulders, neck and lower back and feature Manfrotto’s state-of-the-art AirSupport breathable harness and back panel, adjustable sternum support, shaped hip and waist support systems. A side handle helps users put the pack on or take it off, while elastic side pockets keep water bottles outside the critical gear zone.
The removable Manfrotto CPS insert safeguards equipment right at the heart of the pack and keeps it organized with the efficiency of a portable studio:
The entire internal space is padded to protect camera gear but can be also configured to accommodate accessories and personal gear as well. The main zipper comes with four pullers, which can be divided by a stopper into a top and lower compartment. Just open the top zipper for rapid access to frequently used contents from above.
A smart NeverLose tripod connection secures both longer and shorter tripods on the side of the pack. The connection straps are stitched in the side pocket and can be tucked away when not in use for a tidier appearance and to prevent straps getting lost.
The bigger Bumblebee-230 PL also features a lens pouch located in the waist belt. When not in use, the pouch can be flattened by tightening the webbing strap. (This feature is not available in Bumblebee-130 PL.)
Manfrotto’s new Bumblebee Messengers have significantly raised the bar for their category: a combination of flawless design and reliable performance, they meet all the needs of demanding professionals who travel light and fast. Like the backpacks, the messengers’ body-gripping fit and 3-point AirSupport harness system is breathable and perfect for prolonged outdoor use. The length of the strap can be rapidly adjusted using the EasyGrip buckle.
Despite their compact size, they hold a substantial amount of professional gear:
These bags introduce the XtraSecure handheld gimbal-carrying solution - a stretchable band that holds the gimbal’s moving parts so it can be taken out quickly. The area can also be used as a traditional lens compartment if there is no gimbal in the bag.
Manfrotto’s Bumblebee Messengers feature a secure silent quick-access flap. When shooting in quiet environments (e.g. during a ceremony), apply the NoiseFree Velcro silencer to keep a low profile. The broad front organizer keeps everything on hand. There are two bungee cord straps to hang a small tripod, monopod or selfie pole, which are also protected by the front flap. The Bumblebee Messengers can hold a gripped DSLR body when you take out the laptop from its compartment.
All the bags of the Bumblebee collection come with a DuoFace sun/rain cover to protect from rain, reflect sunlight and keep the gear cool and dry all day long.

Image quality results have been added to the Sony a9 page.
You will like recognize that these results are not from the standard Canon EF 200mm f/2L IS USM test lens we tested the Sony a7R II and most Canon cameras with. The plan was to test the a9 with the same lens, but unfortunately, our FotodioX Canon EF Lens to Sony E-Mount Camera Pro Fusion Smart AF mount adapter is apparently not compatible with the a9 (known adapter-compatible Canon lenses did not work on the a9). So, we went with plan b, testing the a9 with Sony's premier FE 70-200mm f/2.8 GM OSS Lens at a low-distortion focal length.
Keep in mind that the lenses used in these comparisons are different:
Sony a9 vs Canon EOS 1D X Mark II
Sony a9 vs a7R II (vastly different resolutions)

Photomatix Pro Version 6 adds a new rendering style option, corrects perspective problems, and gives more control over color.
Brighton, United Kingdom – HDRsoft announces the release of Photomatix Pro version 6. The latest version of their software application that helps photography pros and enthusiasts create HDR (High Dynamic Range) photos in a large range of styles, from realistic to artistic.
Key benefits in the new release include:
Photomatix Pro merges photographs taken at different exposure levels into a single HDR image with options for automatically aligning hand-held photos and for removing ghosts or visual artifacts when moving objects are present in the scene. Merged images can then be adjusted with a range of precise controls and settings or with one-click presets. Photographers can quickly get the look they desire from natural-looking results to painterly images, from surreal and dreamy photos to ultra-realistic images with increased details.
Photomatix Pro can also be used to enhance a single photo to boost its shadows and enhance its highlights. The program includes a plugin for Adobe Lightroom for users who want to integrate Photomatix Pro into their Lightroom workflow.
"What's unique about Photomatix Pro is the full range of styles it offers to render HDR photos, and version 6 makes this even better," said Geraldine Joffre, HDRsoft Managing Director. "Unlike other apps which rely on one HDR rendering algorithm, Photomatix comes with several. Each algorithm can give an entirely different look with enhancing tones and details or fusing multiple exposures together. Photographers will find it useful to have several alternatives for processing HDR photos as things change with different subjects or lighting conditions."
AVAILABILITY
Photomatix Pro 6 is available now for $99 USD for a single-user license. Customers who purchased Photomatix Pro 5 will receive a free upgrade. Earlier versions of Photomatix Pro can be upgraded for $29 USD.

When a unique weather pattern arrived with numerous little rain storms showing on the radar, it seemed like a good time to go trail running with the lightweight Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens. After photographing some distant storms from a high vantage point, I took a direct hit from one of them. But, that was good news. Rain storms make rainbows and this one delivered superbly.
Also delivering superbly was the Sigma 100-400. While a telephoto zoom may not seem like a first choice for landscape photography, this focal length range is excellent for that purpose (and many others of course). And, using a telephoto lens for rainbow photography is often a good idea.
It was a good night for a run with the camera. In addition to some intense rainbow images, I brought home a large number of nice dramatic sky images including at sunset – and got some exercise.

Image quality (results from 5Ds R, 1Ds III and 7D II included), vignetting, flare and distortion test results along with specs, measurements and standard product images have been added to the Zeiss 15mm f/2.8 Milvus Lens page.
I expected better from this lens. It has the same optical design as its predecessor, but ... it is not performing quite as well as the Zeiss 15mm f/2.8 Classic Lens I owned and loved for years. Typically, if we think a lens is not performing optimally, we test another copy. But, this is the third copy of this lens we have tested and this one has the most-equal corner performance – it is the best of the three.
