I took my Sony RX10IV camera to look for tadpoles at Huntley Meadows. It’s really hard getting a picture of a tadpole breaking the surface. I thought some tadpoles had expired, they didn’t move much, but prodded by other tadpoles they moved soon enough. To emphasize the shape of the tadpole, I converted the pictures to black and white and really raised the contrast and sharpened the image. Murky water can be a problem.
