Nice work. Photo questions: What is the 35mm full frame equivalent of the 10mm lens you are using on that Olympus? Any correction for the wide angle perspective done in post processing or is that as shot? Is that all available lighting, or are you adding lights? Are you gelling your lights to match the available lighting if so? I see a bit of blue/green cast from the window light, but could be anything on my uncalibrated monitor. Have you ever though about actually changing bulbs in the home to all match for better color? Or do you think that would be overboard except on maybe a 1.2 Million dollar dorm, lol? Are you using a really low contrast setting in camera for detail in the shadows and to not blow out the highlights too bad? Shooting raw, I assume, and massaging in post processing? Have you ever tried any of the cameras with special HDR modes for real estate photography?
I tend to shoot wider than most real estate photographers, some of those shots are at an FF equiv of 14mm, though not all. I shoot from between 14-18mm for my interiors. Most of my shoots are in smaller spaces and that 14mm comes in handy, especially for smaller bedrooms and bathrooms. My lens is a 14-28mm ultra-wide FF equiv micro 4/3 on an Olympus OM-D EM1 MkII. I just recently started shooting at 14mm though, previously my lens was an 18-36mm FF equiv ultra wide.
I get my lines as correct as possible in the camera both using the in-camera leveling plus my own additional adjustments, and then correct with Adobe Lightroom's transform settings in post. For this shoot I used no additional lighting besides ambient. I do use a powerful hotshoe METZ flash for other shoots so I can get the window views, but with ceilings this high it was probably pointless so I didn't bother. The light temperature in this place was probably the toughest thing really. Everything is shot in RAW, imported into Lightroom, exported for HDR in Photomatix then re-imported into Lightroom for additional processing - I have a little HDR Awesomeness preset I created and use for every shot, plus tweak the lines, exposure and white balance a bit more mostly. No special settings in camera.
My paygrade is not high enough to change lightbulbs and bring in lots of lighting. The going rate for real estate photography for realtors around here is about $120 per shoot. That includes travel time, on-site and editing. I work for myself.
A high end architectural magazine is probably not going to hire me - my clients are 99% agents with some designers and contractors mixed in. I have shot properties in the millions of dollars but are usually sub 1 million - anywhere from 250K to 1 million. Although this week I shot a 1.65 million dollar brownstone, a 1.25 million dollar 2 family and this 1.2 million dollar loft. Real estate is expensive around here. I live within a few miles of NYC in NJ.
