The year was 2003 when I purchased my first DSLR, spent ₹ 1.75 lacs on the 6mp camera body & another ₹16000/- for 2 Compact Flash cards of 512 mb each. Thankfully the existing SLR lenses were compatible. It was the time of transition from film to digital technology for professional photography . With film cameras editing was taken care of at client’s end, there was no real need of laptops/computers at the time and location of shoot.

This was also the time of shooting with both technologies, film as well as digital, the clients were not sure about the output and quality of digital cameras. The camera which I was using, Fuji S2Pro, had the option of clicking in TIFF mode besides JPEG, RAW processing was not common as editing software were not very advanced unlike today.

On a 512mb memory card, there was a possibility of storing only 28 images, each file size being around 18mb, lesser than a film roll with 36 exposures and almost double than medium format film rolls. Two memory cards were always insufficient for the days shoot considering exposure bracketing.

Buying more memory cards was not a cheap option and laptops were not inexpensive either.

As a standby during that time I requested my friend to bring the Digital Photo Copy Cruiser by Alera Technologies from USA, it was never launched in India and I paid around ₹10000/- for it. I read about this product in an international photography magazine, not much of information was available on internet during those days.

This product was revolutionary which enabled the copying of digital photos directly from camera memory cards to CD without a computer. Each CD can store 700mb data which was more than sufficient for one memory card of 512mb.

This device with two memory cards and lots of blank CDs became an integral part of my camera kit bag and served my purpose for many years till the time memory cards started coming with higher storage capacity and became affordable.

Photos from memory cards could be added to the CD in multi-session format so the full capacity of the CD could be used, though I never used this feature . It could also be used as a USB 2.0 36x CD recorder when connected to a computer. The Digital Photo Copy Cruiser supported the following Digital Memory Card formats: CF Type I and II, SD, MMC, SM, MS, MS Pro, and Micro Drive.

I read somewhere that this device became very popular with intelligence and detective agencies as it didn’t leave a trail since no computers were used to transfer the images from the memory card resulting in utmost secrecy.

The technological advancements in last fifteen years or so has made a tremendous impact on photography, cameras have become much more affordable resulting in democratisation where more people are able to pursue the craft either as hobby or profession. The initial days of transition from film to digital was a great learning experience, things were changing at a rapid pace as compared to present. It is now the time again to concentrate on the art of photography rather than worrying about the changing technology.

Canon Speedlite 470EX-AI Review

New products, new models  are launched almost every day, most of these are either result of remodelling of the existing range or some improvements in the previous ones. A technical breakthrough is not very common, to come up with something innovative and unique decides the future of technology. The innovation opens up avenues for advancement and improvements and further opens doors for more innovations. 

There are various models of speedlites available for the photographers, some are dedicated ones manufactured and marketed by camera companies and some are sold by third party vendors. Most of these camera flashes are identical in nature, these are “kind of standardised” and offer default features. 

The new Canon 470EX-AI can easily be called a revolutionary product which is breaking barriers. A true innovation which will change the way speedlites are designed and used. AI stands for Auto Intelligent and is actually intelligent enough to make flash photography extremely simple even for amateurs.

 

Photograph below is taken without flash in extremely low light situation resulting in noise.

Camera EOS M50 , Lens: EF-M15-45mm f/3.5-6.3 IS STM, 45mm, f6.3, 1/16sec, ISO 6400

Direct flash whether in-built on the camera or external speedlite though light up the subject but cause unpleasant shadows.

Bouncing the light either using white ceiling or white walls using external flash is widely used by photographers to evenly light the subject. Using bounce flash is complicated, need experience and expertise. Canon 470EX-AI, world’s first flash with an AI Bounce function, has made this process extremely simple, press of a button on the speedlite invokes the intelligence and makes flash photography a cakewalk. 

Besides working as a normal external flash with all controls typically present, setting it on  F(Full)-AI.B mode totally changes the way this speedlite acts. After composing the scene in the frame and pressing AI.B button, the speedlite performs a few operations- measuring camera/subject, and subject/ceiling distance, the flash head swivels in multiple directions to formulate the ideal bounce flash angle and automatically sets for optimum flash output for bouncing the light, no more unpleasant shadows. While changing the orientation of camera from horizontal to vertical or other way round, pressing shutter release button twice realigns the flash direction and gives the exact same result.

When the subject-camera distance is changed, pressing the AI.B button will repeat the process and recalculate the ideal angle for bouncing the light and optimum output.

In AI.B Semi-auto mode, photographer can set  their own bounce angle settings and the flash can automatically maintain its angle even when there is a change between horizontal and vertical camera orientation. By pressing the shutter button twice the flash head automatically moves into the preset angle and position.

In the photographs below the mode chosen is S, Semi Automatic and the flash head is pointed towards wall on the side, once on left side and next on right side. The flash head automatically rotates towards the set angle when camera orientation is changed from horizontal to vertical. With the light bouncing off the wall on side, there is a nice play of light and shadow on the face.

When it is difficult to autofocus on the subject in low-light or when contrast is low during viewfinder shooting, the infrared AF-assist beam built into the flash is automatically emitted to help in autofocus. With this flash mounted on the camera, focusing in low light conditions will no longer an issue. All these photographs have been clicked in low light and there was no issue in focussing on the subject whatsoever.

As mentioned before, the M (Manual) mode will make the speedlite like any other normal external flash, the flash head can set in the desired angle manually  irrespective of camera orientation. It is only in S (Semi) and F(Full) Auto Intelligent Bounce mode the speedlite takes control of the situation and sets the angles according to the distance between subject/camera and subject/ceiling.

Canon 470EX-AI is meant for both professional photographers who are seeking more automation as well as for amateurs who are clueless about flash photography. The speedlite is most suited for covering events, clicking portraits and even products where the subject get evenly lit with nice soft bounced light.

All the Portraits above are taken with the mirrorless camera from Canon:

Canon R Full Frame Mirrorless Camera

The wait is finally over, as expected Canon has come up with a full frame mirrorless camera. Canon introduced crop sensor mirrorless cameras around four years back but did not aggressively promote these till EOS M50 was launched sometime back. With the competition increasing in full frame mirrorless category cameras, Canon has come up with EOS R system – Reimagining future. It is almost after 30 years after introduction of EOS and EF mount , a major change is being brought in with the new R mount.

Continuing with the philosophy of selling cameras which provide excellent image quality, ease of use and durability, the magnesium alloy body with the patented grip and placement of buttons makes this camera not only durable, easy to handle but good looking too.The diameter of mount remains the same at 54 mm but the distance between the mount and sensor plane has come down to 20 mm which in future will help in designing better quality compact lenses with wider aperture like f 1.0

The programmable ring on lens to control exposure and touch bar with multi functions on the body are the new, unique and innovative features offered, both of these will make clicking photographs faster with more ease.

Powerful image stabilisation (IS) effect of upto 5 stops

The algorithm to detect camera shake is an evolution from that of EOS DSLR cameras. This IS system acquires camera shake data from both a gyroscopic sensor in the lens and image data from camera’s CMOS sensor. The Dual Sensing IS system can accurately detect and compensate for low frequency (slow) blur that used to be hard to detect with gyroscopic sensors alone. As a result, camera-shake blur is reduced by the equivalent of a 5-stop faster shutter speed.

Combination of optical and electronic IS systems greatly reduce blur caused by low frequency camera shake. When a compatible lens is attached, the camera’s combination IS system uses both the Electronic IS for movies( in the camera) and optical IS in the lens, to significantly improve the performance of 5 axis camera-shake blur compensation.

Right now four R mount lenses have been announced but with the adapter all EF and EFS lenses can be used. The battery remains the same as in 5D & 6 D series, LP-E6/LP-E6N and so does the memory card. All these features are added advantage for photographers who are already using Canon DSLRs or new users who are planning to buy one and want to buy the R mount camera as their first body or an extra body.
