My lessons from this exercise:
1) My preference remains with record images in raw format supplemented by tiff or jpeg as a second choice. I am still of the opinion that raw format offers slightly more flexibility and choice. However, this exercise proved that the value of raw format is the highest when the lighting conditions are challenging. It is less obvious when the lighting conditions are standard.
2) It might be easier and faster to process raw files in
Adobe Lightroom though the Photoshop raw converter has similar tools to those available in Lightroom (recovery, black, clarity).

3) I have noticed some slight variations in how the colours are reproduced in JPEG/ raw images. These variations usually more obvious when the lighting is tricky and when some extra adjustments are necessary.
4) Raw images seem to reproduce the colour more accurately.
5) The exercise was a valuable opportunity to look critically and objectively at how different formats perform at different lighting conditions and how the image quality is affected.
6) Using a well-defined workflow helps to become more consistent in addressing any issues / differences and achieving consistency in practice.
7) This exercise also demonstrates the importance of using a well-calibrated computer system whereby each component has specified gamma values for its input and output. This would mean that where an appropriate gamma correction is applied for the system, the output would accurately reproduce the image input.
