I had the opportunity to visit Hudson River Park in New York City today. It offers terrific views of the city. After a fruitful daytime visit, I look forward to visiting the park for a night shoot. As it was, this location provided the perfect opportunity to show how telephoto lenses compress the image. While wide angle lenses makes the background seem further away. The first picture was taken with a 24 to 105mm lens at 24mm's and the second was taken at 8mm. Despite both of these lenses being relatively wide you can see way more compression in the first image. So, if you want to make the background seem far from the foreground or you want to show more of the background, use a wider lens. If you want to unclutter the background as to drawl more attention to the foreground use a longer lens. This is even more pronounced in the 3rd and 4th images. The 3rd was shot at 35mm's and the 4th at 8mm's. The 1st and 2nd images were taken from the same spot and the 3rd and 4th were taken from the same spot. I hope if nothing you enjoy the images. The 1st and 3rd images are featured in my fine art store. They can be purchased here.
