When to go
Best time
Morning, Mid-day, Late afternoon
As long as the weather is overcast, you'll be able to photograph the Roman Baths during any month. I suggest visiting in March or May for a moody England effect.
Visit the baths in the morning as early as they open to beat the crowds. In the midday and late afternoon, you can also find similar lighting conditions.
Field tips
As this is a historical site, please be respectful of others while they visit The Roman Baths.
Using a wide-angle lens (18mm) will allow you to frame the beautiful surrounding architecture.
Try to wait for the mist to gloss over the baths to evoke the feeling of what the Roman Baths were like thousands of years ago on a foggy day.
Incorporate the visitors in your shot to add a human element and to create a sense of scale.
