The Stitching Process

After importing the images into photoshop and merging them all into one, I have started stitching the image together. The main tool I am using for this process is layer masking, painting transparency and opacity over the overlaps of the image. 

As you can see from this image, every layer has a layer mask. By using different brush opacities, sizes and softness, it is possible to create a "blend" over certain surfaces. 

This image shows the colour shift between the two layers. This is the best I can get the colours to match (even though it's pretty bad) However, before this it was extremely different colours. I used the Colour Match tool (Image > Adjustments > Match Colour) and selected the previous layer to match the colours from. However, it has created this pixellated effect which makes the panorama look amateur. This is still the best I can get the colour shift to match.
