Overcast days are great days for taking photographs. There are no harsh shadows and the sky will take on a gray or sometimes almost a white appearance whether you are taking color black and white photographs.
It is still best to have the sun, which you cannot see, at your back. But even shooting into the sun will not give you any problems. If you are using a camera which automatically sets your exposure, you will want to aim it at the subject and not up into the sky. Otherwise, the sky, which is still bright, will tend to give you an under exposed photograph.
The two scenes with this blog, one in color and the other in black and white, were taken on the same morning. probably within an hour of each other and about 15 miles apart. in Nova Scotia.
The color Pastel Boat Harbor scene provides a soft rendition with the water reflections of both the boat and the building in the background. This was the second photograph taken that morning and you can see just a bit of blue sky breaking through in the upper left hand corner.
The black and white “Barrel Factory” was taken earlier and the sky here is void of any contrast or clouds.
The old wood in the building, wood shingles, and certainly all the birds on the roof, make this a very interesting scene.
