You can reduce the contrast by taking the photo when the outside ambient light is equal to the inside light... Sunset or around there depending on the direction the window is pointing. You should also try using multi point exposure an then adjusting the highlights down and low lights up in Photoshop. I am not familiar with the capability of your camera but my D800 would get both inside and outside perfectly... But it has a full sized sensor. Good luck, you are on your way. JD
