Canon’s HDR In-Camera Review

After several years waiting for the Canon 5D Mark II’s successor, the last year it appeared the mark III. The substitute camera has enhanced Focus System, Video and fps, and more things… They have been included new features as in-camera multi-exposures and an HDR Mode too. So if you don’t know, cos you don’t follow me on Facebook, this is my new camera.

I am going to preliminary review (less than 10 days with my new toy) the HDR in-camera.

How to use HDR with Canon 5D Mark III:

The EOS 5D Mark III has a new button on the left-rear of the camera, called the ‘Creative Photo’. Marked with an icon of a paintbrush, it’s a short-cut to three commands related to image control on the EOS 5D Mark III: Picture Style, Multi-exposure mode, and HDR mode. Pressing this button, scrolling to the HDR icon and pressing the SET button instantly brings-up the full HDR Mode menu.

Another option is to select AEB in the shooting menu. Then, they are until 7 exposures available for shooting, more than 3 for HDR mode, but the camera doesn’t generate an HDR picture. Just let you to process the files later using third-party HDR software. HDR Mode shooting cannot be combined with BULB mode, so you need to set manually the exposures or do it automatically using SW like Magic Lantern or hardware like Promote Control.

Or you can select HDR Mode in the camera’s Shooting Menu > Select Bracketing to +-1/+-2/+-3 are available(-+2 by default).And an AUTO option,when the camera reads dynamic range and on its own makes a determination of the exposure compensation needed for three bracketed shots > Choose the Image Effect that you want in the finished picture ( I select ‘Natural‘ by default) > Select Continuous HDR if you want to have several HDRs, not only one (‘1 Shot On‘ option enable).

Another settings are:

– Select your camera to save files as RAW without compression.
– Set Aperture Priority Mode.
– Set other parameters in the camera like ISO or aperture as you wish.I usually select AUTO ISO for handheld exposures.The camera has the ability to automatically select the slowest shutter speed used before it starts increasing ISO in AUTO ISO mode and it does this based on your focal length.I select ISO 100 when I have the camera on a tripod.

The camera captures 3 consecutive shots at a fast fps rate (+2 EV , 0EV , -2 EV with default settings) and generates a JPG file with the processed HDR image. The camera software aligns the images (with Auto Image Align menu option activated), but doesn’t resolve ‘ghosting effect‘ due to objects in motion in the scene.The final HDR image has slight even if there was essentially no camera shake or movement during the bracketed shooting sequence.

Finally, we can compare the results of HDR images generated by the camera and another ones processed using Lightroom, Photomatix and Photoshop. The Canon HDR images have blue hues and more cropping than the processed HDR images. The shots were taken with Auto White Balance, so I think that if you compensate it in the camera you can get a best result. I corrected WB in Lightroom previously to HDR processing in Photomatix. Besides, I processed lens corrections ( chromatic aberration and lens distortion ) in LR5 Beta. Saving the exposures with LR presets as TIFF 16-bit files. To generate an EXR file, I used HDR Pro in Photoshop, selecting 32-bit mode and to avoid disalignment, choose the 0 EV exposure to avoid ghosting and correct camera shake for the hand-held exposures.

In conclusion, HDR mode in camera is useful to have an idea of how will be your HDR image and to know if you exposures cover all the dynamic range of the scene, but the cropping inside the camera, the problem with alignment and ‘ghosting’ do that it will be better to process yourself the images.

Multi-multiexposures. We, photographers, love Photoshopping

If someone has wondered why I use HDR the respond is – as I commented a few days ago with a photographer buddy through Facebook – maybe, ‘cos we are crazy and we love editing pictures.

In fact, he was telling that he had problems manual blending the lights and shadows of a metallic tower structure. I suggest him blending it automatically using Fusion Mode, for example, in Photomatix and later doing little changes with the exposures manually in PS.

But on the other hand, from a technical point of view, the use of multiexposures techniques is due to the limitation of cameras. The human eyes can see more tones than a camera sensor. And scenes like night-shots have extreme highlights in the bulbs, for example, and dark in the sky. So it is necessary to cover all dynamic range to use DRI or HDR.

And we can go far away, and do it more complex with something that we can call with a new ‘term’ as multi-multiexposures. I am going to explain it with some examples:

HDR/DRI Pamoramas or Vertoramas: a composition of several images horizontally or vertically overlapped between them, taken 3 or more exposures for each one. Processing them individually and merging them later with a panorama edit program. Someones prefer another workflow – as you wish – each one has its advantages and disadvantages. See Klaus Herrmann.

HDR/DRI Time lapse. It this case, we combine images at different time but focussing the same spacial elements, so we capture how some objects are moving in the scene, for example the clouds motion and how the light changes in the scene in the static elements, for example the ground.

Stars trails. A composition of trails generated at different time intervals. For example, each interval for a bit of curve generated from an exposure of around 30s with interval of 5 s with the following one. Later, all exposures can be stacked with a special program like StarStaX, in order to generate curves (stars lights trails).

Full control of DOF. To clarify the situation, the example can be marina shot with artificial lights at blue hour. The approach can be an HDR or DRI to cover the scene but the problem are the boats on the foreground. As a night-shot, to get more sharpness and less noise, it is usual to shot with a small aperture, around f11-f16, and low ISO, around 100-400. But then, the long exposure time does that the boats near the photographer are moved and as consequence we have objects with blur. Then, to get them with sharpness you can shot with a wider aperture or increase ISO. You should take a compromise between reducing DOF or increase noise in a little zone … just the boat. That depends on your camera. Changing aperture to change the focal plain. So if you combine these images, you have the same result as in macro photography when due to little distance to subject only a little zone of the photo is in focus and you can blend different shots with different focus zones to get the overall image in focus.See Daniel Cheong.

Digital Art. Another option can be multiexposures for photo montages when you want different images to do a composition or transparencies or matte-paintings (see Giuseppe Parisi).

Boats At Portree Harbour

The Isle of Skye and its surrounding environment are from my point of view, the best scenery in Scotland. If you have only the opportunity to be a few days here, you should go to the Eilean Donan Castle and to cross the channel until this isle. I know that I didn’t see the overall isle, just a few sites but it is amazing to visit the Kilt Rock Fall, the Storr, the Dunvegan Castle, … and other ones that I didn’t see like Elgol, Cullin Hills …

The main town in the island is Portree. The current name comes from the Scottish Gaelic ‘Port Rìgh’, that can be translated as ‘king’s harbour’, possibly from a visit by King James V of Scotland in 1540. The older name appears to have been Port Ruighe(adh), ‘slope harbour’.

In the picture, a tipical panorama from the harbour, with the green mountains on the background in contrast with a silver gray sky and the usual transient light.
