Can I make it fail?
Sure I can. At least I can set up situations that play to the strengths of one tool or another.
Here is an example where auto white balance is handed a pretty easy target to assess given the assumptions of the awb system. AWB here is far from perfect, but it is closer than either of the other tools.
By the same token I could hand pick a few special unique situations where the somewhat more targeted angle of view of the Color Parrot puts it at a disadvantage over a wider angle of view.
Overall, however, this tool has been designed around our understanding of how the typical live event photographer uses their equipment and goes about their day.
We believe The Color Parrot produces the best overall results in these situations.
