Welcome

Welcome to StillMotography Plus! As the world of imaging has changed, growing numbers of image-makers, whether professionals with clients or enthusiasts, want to generate both stills and motion content. If you are shooting stills and motion with your camera, you have entered the world of Still-mo-tography and you are quite possibly a stillmotographer!
In the two and a half year life of this blog, the universe of cameras capable of capturing stills and motion has grown tremendously. While the Nikon D90 and the Canon 5D MarkII HDSLR cameras may have kick-started “stillmotography,” the number of cameras that have been introduced that are capable of delivering stunning stills and motion clips is astonishing and we’re talking about going way beyond the traditional DSLR. Our name change from HDSLRS-n-Motion is recognition of the expanded universe of not only cameras, but of products which can be of value to the Twenty-First Century image-maker. Welcome to a brand new world!
So Please come back often and check us out at www.stillmoplus.com!

HDSLR Camera Accessories: White Balance Aids and Remote Controller Options

White Balance: The Foundation of Color Accuracy and Creative Editing
A white balancing reference aid can be an invaluable tool to take along with your HDSLR for use before and during motion capture. The reasons to custom or manually white balance your HDSLR video footage are the same as for doing it for still work: It allows you to make the decisions with respect to your color accuracy rather than relying on the camera to do so, and enables you to maintain greater control and consistency throughout your shoot. Setting a custom or manual white balance can reduce the need for some color corrections during the editing process. Additionally, accurate color capture is an excellent departure point for creative grading. While white balance is often spoken of in terms of color accuracy, it is as much about a pleasing appearance and /or the look you choose to create. If you are just beginning to shoot video and are editing with software that has limited color correction options, setting a manual or custom white balance may become even more important.

There are two ways to achieve in-camera custom/manual white balance:  The incident or reflective methods. The incident method of white balancing  involves placing a neutral "filter" over the camera lens and shooting a reference frame from the position of your subject, to measure the light and color of light hitting the subject. Popular aids using the incident method include Expo Imaging’s Expodisc and the Brno BaLens cap. The reflective method involves shooting a neutral gray or white card, and capturing and measuring the color of the light reflected by the card from the subject position back to the camera sensor for the reference frame. Products such as WhiBal, Vortex Media’s White Balancing Reference System, and a host of other 18% grey or white card-type products use the reflective method of measurement. Whichever method you use, the reference frame is used to set the custom white balance (you should refer to your camera manual for specific instructions as to how to use the reference frame to set the custom white balance).  As lighting conditions change, you should repeat the process for the best results. Is one better than the other? It really comes down to a matter of choice. Choice also extends to product price-points as there are white balance aids available at a variety of prices.

While there is a lot to be said for using products that have been manufactured to be color neutral or expressly to warm, cool or produce other specific results, there are people who use items like coffee filters and translucent plastic lid caps, as well as simple white paper or fabric to white balance. A word of caution, about using some of these products: White paper and fabric often contain brighteners or bleach which reduces their neutrality, and can result in color cast, so be careful.

Remote Controller Options for Canon’s 5D MarkII, 7D, Rebel T2i, and Rebel T1i Cameras

Do not underestimate the ability to stop and start the video functions of your camera via a remote controller. The benefit is that to the extent you do not have to touch the camera, you reduce the potential for causing camera shake. And with options from Canon that retail for under $30, the remote controller units should be essential for HDSLR shooters. The Canon RC-1 and the RC-5 (as well as the newly announced RC-6 remote controller) are capable of starting and stopping  camera video recording. The main difference between the RC-1 and RC-5/6 is that the RC-1 can be used for instant shutter release or a two second delay for still shooting while the RC-5/6 only has the two-second delay for stills. For stopping and starting video, you set the camera drive to one of the timer release modes. With the RC-5/6 you are ready to start your video by pressing the release. With the RC-1, you simply slide the switch to the #2 position and you can start and stop video recording by depressing the release button.  There is no delay when the controllers are used for video work.  Now the one drawback to the Canon remote controllers is that they require proximity and/or line of sight to the camera’s Infra-Red (IR) lamp on the front right side. I indicate proximity because depending on the camera model and the placement of the IR lamp,the start-stop can sometimes be activated if the controller is close enough without actually  having direct line of sight; but I would not want to take a chance or advise users to count on proximity working in the majority of situations.  Always strive for line of sight.

In order to address the proximity issue, Long Island-based Switronix has developed the Flex DSLR remote, the base of which can be mounted to a tripod or stabilizer. The Switronix unit uses a flexible gooseneck to allow the remote optical trigger to be placed in front of the camera’s IR sensor. The ability to position the optical trigger in this manner results in flawless wireless stop-start of the video functions without having to hold a remote controller in your hand.  While the Flex DSLR which sell in the vicinity of $150, is expensive relative to the Canon remote options, many users, especially those using the cameras for professional applications, will find it an attractive and viable solution.

So there you have it-- some additional items to consider adding to enhance your HDSLR motion capture experience. Feel free to click on the product insert below to get more information on some of the products mentioned in the entry as well as a few others which are noteworthy. Please note that the white balance products in the inset utilize the incident method of measurement. A separate entry on white balance aids which use the reflective method will be posted within the next few weeks in our companion blog www.hdhd411.com.

HDSLRs: The Ranks Continue to Swell

I have expanded the exhibit of cameras that was included in the inaugural issue of “Outfitting your H(d)SLR” to include the newest members of the class. The models have increased from two in the fall of 2008 to twelve today (including the Panasonic GH1 which is technically not a HDSLR.) That number will continue to grow as the interest in multi-media collateral for personal and business applications continues to grow. I have to admit that I was surprised that Sony released new DSLR models over the last several months without video capability.

But before we get to the chart, let’s look at a few statistics:

• Social networking continued to gain momentum in 2009 with nearly four out of five Internet users visiting a social networking site on a monthly basis

• During December 2009, 86.5 percent of the total U.S. Internet audience (up from 79% in April) viewed online video.

• During December, 134.4 million viewers watched more than 13 billion videos on YouTube.com (97.1 videos per viewer) versus 107 million viewers watching 6.8 million videos (64 videos per viewer) in April 2009.

• 44.9 million viewers watched 423.3 million videos on MySpace sites (9.4 videos per viewer) in December 2009 versus 49 million viewers watching 387 million videos (8 videos per viewer) in April 2009.

• The duration of the average online video was 4.1 minutes in December versus 3.5 minutes in April, 2009.

What is clear is that the demand for video continues to grow.

In terms of the chart, I have included the Panasonic Lumix DMC-GH1 because although it is not a DSLR, there are aspects of the video implementation which are superior to some of the HDSLR offerings in the market, and its price (which includes a video optimized zoom lens) makes it competitive to some of those offerings as well.

The H(d)SLR Evolution – Beyond the Stills and (e)Motion


I was very excited with the announcements of the first HDSLRs nearly a year and a half ago. The promise of being able to capture some quick video clips while shooting stills was so alluring. During this period I have been shooting still and motion, I have not only shot clips as part of still projects, but ventured beyond. I asked myself if I was just getting caught up in the film making juggernaut or was there something else going on. After a lot of examination, I concluded that my thought processes and use of stills and motion was a natural evolution, which happens with availability, exposure and comfort. Do I consider myself a film maker or aspire to be one? Not by any stretch of the imagination, but I do find myself thinking about my work differently: I now consider motion capture as a part of my normal shooting options. Motion capture is also something clients looking for stills do not even know they want–until they see it.

While HD video is a feature which I showing up on a growing number of new DSLRs, it is still in its infancy and therein lies the problem: Whose baby is it? Is it for the enthusiast who is buying the camera primarily for still capability to capture personal images? The inclusion of HD video on entry and some mid level products from Canon, Nikon, Panasonic, and Pentax, would suggest that it is. Is it for the budding film maker? The changes that Canon in particular has made since the introduction of the 5D MarkII in frame rates and controls, says it is. The huge number of accessories available from manufacturers to make Canon, Panasonic, and Nikon HDSLR offerings more “movie maker” friendly, suggest it too.
And of course, the inclusion of video capture on the “professional” photojournalist and sports big guns from the big two DSLR makers suggest that the motion capture has professional overtone for even these primarily still shooters. It seems that the HDSLR is everyone’s baby!

The challenge for some HDSLR users is figuring out how to use this capability without taxing their budgets and intestinal fortitude as it relates to getting their motion work from the camera to the Web or small screen. This may describe the people who want to use the video capability without having to get into the intricacies of codec and wrappers or can warrant/justifying spending a “king’s ransom” to make their camera more video friendly. The good news is that they do not have to if they choose not to. They need to be thoughtful with respect to the equipment and software they are considering. They also need to remember before they start shooting that motion capture is about the visual story and sound.

Film makers and aspiring film makers have a different set of challenges. They understand the significance of the story and sound. The film maker is often working with other people with specific expertise and defined roles in the movie making process. They need to make a tool with drawbacks and limitations work for them. Obviously, the limitations pale in comparison to the benefits derived from the larger chip and greater depth of field control that HDSLRs and the lens options offer at a fraction of the cost of traditional movie cameras. How important are film makers to the HDSLR evolution? They are very important, and Canon, cites film makers’ desires and needs as a factor in changes and further development and refinement of their HDSLR offerings.

While the film maker is concerned about camera stabilization, more often than not, the concern is over stabilizing more than just the camera. A host of other accessories and equipment is often used to optimize their capture work. The need to attach sound equipment, focus follows, matte boxes, and monitors among other items. The film maker also has a different set of video editing needs and will usually require substantially more expensive and/or involved software solutions. The use of separate recording devices can add another level of complexity to after-capture work flow as the footage and sound must be synced, and multiple tracks of sound may be needed. The advantage the film maker picking up a HDSLR has over other users is a better understanding of its limitations, as well as what things they will need to make it work for them.

For the camera makers all of this means that they have a lot of markets to address and try to keep happy. A few years ago, the concerns were over dynamic range, improved autofocus, better in-camera white balance, and other things relevant to still capture. Today, in addition to having to address issues related to and improving still capture, the DSLR manufacturers have to address issues and enhancements related to motion capture. It will be interesting to see how everyone’s baby grows up.
