Look at it this way!
Nobody is gonna buy a house sight unseen from a picture. Real estate photos shod just create interest and desire for the property and give the potential buyer I good idea of what the place looks like. If the picture and the accompanying copy are decent enough the buyer will make an appointment with the estate agent and see the house in person.
The potential buyer will not usually worry about colour accuracy or saturation or otere technicalities with reason. So, any criticism I offer will have to do with how what you do affects the viewer. If you are havg issues with certain technicalities as to colour accuracy, contrast, saturation and exposure, you will eventually work these out, For me, the big issue is "staging" and attention to detail.
I realize that you can not change the furnishings but you can make the best of what you have to work with. The idea is not to restyle the entire property but to have the potential buyers FEEL that will be comfortable in that place- shoot it so they can relate to it.
Due to limited time, I just used a detail of one of the rooms in our - want to the colour a bit and to have good "detail shot" shots. I put a fire in the fireplace, cropped out the door and the sofa pillow in the foreground and concentrate on the cozy corner of the room.
In the original shot of the room, I noticed 2 stained glass lams at the edges. If you fully included the in the shot and turned them on, perha exposed for the ambient lig and fill in with a tungsten source, you would have a nice mood shot. Flat lighting causes a lack of dimensionality. It's OK if the foreground is a bit darker- it leads the eye into the room
Make certn pillows are puffed up, and things arein place, remove items wastebasket, etc., and if a door is open, perha ligh and show the adjoining room in the background. Watch vertical lies for off-kilter tilts and distortion. For smaller rooms, you might need a shorter wide-angle lens. Avoid "falling over walls" due to distortion. If you do not have perspective control eons, just keep the camera perpendicular and paralleled and cor the unwanted excess ceiling and floor areas.
There is nothing terribly wrong with what you have done. If you want to improve your work and seek out high-end real estate markets, the aforementioned are a number of suggestions. Thereis a lot of estate photography out there that is rather mediocre but it passes and probably does the job. There is high-end interior work that you see in architectural and interior decoration publications. If you come in somewhere in between you are on the rigt track.
Good luck and much success!
