When I am outside, and truly overwhelmed by the immensity of everything I can see in my natural field of vision, I realize I want a lens that can represent as much of that as possible in an image on a print or a screen. But when I am inside, hundreds of square feet of coffered ceilings just don't call me to the same desire to represent every inch of it I can in an image that will likely be viewed on a phone, or a 27" screen, (okay, on occasion someone will bounce it to their 60" TV screen, too). Once you've seen a few feet of a room's crown moulding, you've seen it all.
The images above are the same shot, taken from the exact same spot, with lenses whose focal lengths differed by a mere 4mm, (18 vs. 14), with the lower number producing the wider shot on the bottom. Undoubtedly, there are hundreds of feet of horizon, many square feet of field & trees, and more sky to go over it all represented in the wider shot. So, there is more stuff in the frame; clouds, trees, grass, rocks, etc., but it is all in a perspective of being further away from the observer, making the details smaller and less distinct, and the details around the edges of the images are a wee bit stretched and distorted. The lens I used was a good one designed specifically for the image sensor on my DSLR, not a knock-off brand, non-optimized design.
So, when thinking about how best to view an interior 3 dimensional space on a flat screen or page, while being able to understand the relationships between the spaces, I am of the opinion that other technologies can be more helpful than simply capturing ever and ever wider and more edge distorted shots. In the second photograph above, the lens perspective is so wide that when I accidentally bumped the hood on the lens while installing it, knocking it slightly out of alignment it therefore featured itself in the distorted edges of the shot. A common mishap with lenses of this type.
Adobe has a Storytelling app called "Slate" that combines text, large and small photos in a flow-by format enabling the use of copy and images in storytelling in a very compelling way. Well thought out photo's by a photographer who has taken the time to walk through the space and understand it's particular flow can be framed, organized and sequenced in such a way that literally walks a viewer through a space as if on a tour, with smaller associated images highlighting features of a room or space embedded in the photo of the overall room combined with descriptive text for all of it. It can be scrolled backward and forward, it works very well on mobile devices, adobe hosts the project on their cloud which the user/author pays to rent space on, and I believe it to be far superior to just 35 distorted, over saturated, over-lit, over-wide images with Ken Burns effect applied and set to music in a "virtual tour".
So you RE Agents and Brokers our there, it's time to get your State MLS technology systems updated to support the kind of marketing imagery that your up and coming buyers are used to seeing applied for their food menus, news stories and other everyday media, or risk looking more and more out of touch, and entrenched in your aging imagery presentations. Mobile and desktop technology are increasingly replacing "being there" in the shopping experience due to cost, travel and time, and this will only increase more and more rapidly as VR technology becomes consumer approachable and more ubiquitous.
Oh, and lastly, try to continue to rely on freelancers. The rapidly expanding firms that hire photographers, underpay them, impose a system and post production process on them in the name of efficiency really just skim off fees to benefit, (out of sight, and likely idle), owners profits. Imaging technology is moving forward much too rapidly for those techniques and processes to continue to be relevant and attractive for buyers for very long. Ask those companies what imagery innovations they are funding with the profits from their fees. Freelancers can innovate, flex and upgrade their smaller gear kits faster, and they only have to train themselves on new processes instead of a shop full of techs in some far off place. Technology is democratizing the application of skills and crafts and decentralizing innovation. But in spite of technology, Real Estate, due to its relative economic magnitude and personalized emotional response, remains a relationship based business.
