If I am shooting larger items, I try to set up outside and use my flash. Most likely, you can just use the "P" mode (that stands for Professional!

) and your camera and flash will talk to each other and determine the best exposure.
However, if it is a cloudy day or shadows, I will first take a pic of the area without the flash with my shutter speed set at 1/250 on shutter speed priority.
Then I switch the camera to Manual and set the shutter speed at 1/250 sec. I adjust the f/stop to what the camera indicated when I took the test shot.
Then turn the flash on and set it at +1/3 exposure compensation. Take a shot and see how it turns out. The flash should create the correct exposure with a little extra to fill in the shadows. The background will be exposed just the way you took your original shot in shutter speed priority. You can alter the background, say make it darker by increasing the f/stop 1/3 or 1/2. That will make your subject pop!
I also use flash when shooting projects indoors such as the miter saw stand construction. I either use direct flash or bounce it off the ceiling or the wall.
If possible, run your pics through a photo editor to tweak the exposure, contrast, and cropping if needed.
Hope this helps,
Mike
