I have played with Photoshop as an analysis tool to use the scanner as a densitometer in previous posts. This should provide a means of objectively evaluating the results. In this case I selected a larger area in each photo and measured the mean and standard deviation. These I used as proxies for brightness (mean) and contrast (std dev). I plotted these against ASA ISO from above.
Finally I cropped and adjusted using Auto Levels in photo shop the ISO 10 and ISO 25 results.
|ISO 10 No Levels|
|ISO 10 Auto Levels|
|ISO 25 No Levels|
|ISO 25 Auto Levels|
