These five images are of a Meadow Fritillary, Brown Argus and Small Copper looking directly into the sun's glare at about 10am. I noticed some similar shots on the internet and decided to experiment when suitable light was available, ie not in the UK. I took them last week in France.
I raised the exposure to between +0.3 and +1.0EV. Failure to increase the exposure results in very dark images. I also changed the metering to Centre Weighted, ie metered off the subject.
I was pleased with the results as the sun is shown bursting through the translucent whites though still retaining some colour within the insect and the flower (mint).
