1. Fireworks Season is approaching and there are many techniques you can try! One is using the double exposure setting available in Nikon cameras - set for 3 to 5 exposures, ISO 200, auto gain on and single exposure mode. Shoot when bursts are at their peak. This is an alternate to the old bulb technique with the black card over the lens between bursts.
2. Another is Shooting Separate Fireworks Bursts then blending in Photoshop - Use a tripod, a cable release, zoom tele lens, camera on manual with shutter speed around 4 sec, aperture at F11. Manual focus to infinity. ISO 200. Do a test shot and evaluate it and adjust as needed. Take a background image first before the show at a wide angle to use as your background image. Then lasso the individual bursts in Photoshop onto a new layer above your background and blend with lighten. Move individual bursts as needed to line up as you like.
3. Use Black & White to add Drama - especially for dull scenes. Then adjust the shutter speed to slow the movement of water in seascapes to really add drama.
4. Try Intimate Compositions for Seascapes -
The vastness of the ocean invites the photographer to shoot the grand seascape using a wide or ultra-wide lens. But a telephoto can be used to create intimate compositions from coastal scenes, specially if you have rocks. Try different focal lengths to search for a composition you haven't considered, use a long exposure if needed to create an abstraction and you'll have a new photo.
5. Get Close -
Because wide-angle lenses take in a bigger angle-of-view than other lenses, using a wide-angle lens at the same distance from your subject will render that subject smaller than it would otherwise. To compensate for this, you'll have to move closer to your subject. Don't be bashful about getting close, particularly with super-wides.
