For this exercise we must first photograph the same image making two different exposures. One exposure should be perfect for the landscape and the other perfect for the sky. After processing without trying to make any significant compensation, combine the two images.
I have photographed my house as I knew it would be an easy image to get. The first shot has been exposed for the house.
The second exposure has been made for the sky.
I thought that I would give photomatrix a try and so downloaded a free trial version. I was able to merge the photos but as you can see, the clouds had moved between exposures so the image is not a direct fit. Practice and further research is required here to be able to successfully process the image. The exposures had 3 f stops between them.
Part two of the exercise requests that I either take the same image or shoot a new one and combine with a different sky, either new or an existing photo. I have chosen to use the same image of my house which I have cropped and have then taken a different shot of the sky. I have also decided to try and combine them using photoshop this time.
New sky image.
I have combined the shots by using the polygonal lasso tool to select around the roof of the house and have then been able to cut and paste onto the shot of the sky. I was careful to create a layer so that I would not effect the original shot. I actually found this easier and than the method I used for the first part of this exercise. I think that with practice I will improve with the technique. I tried to take into account the direction of the sun when it cam to taking both images as this would have an effect on the end result.
I do feel that the second part of this exercise is more dishonest as it is two completely different photos. The first part was more acceptable as it was a near identical image with the only difference being the exposure.
