Peterff Loc: O'er The Hills and Far Away, in Themyscira.

Use a tripod and a timer. Surely if you want the shot you're willing to make a little personal investment and experience a little discomfort to make a great image.

You might even get the point and learn a few things about sharpness, composition and timing.

These seem like all grand suggestions. You may also look for nesting cavities in the cactus, insects stuck on the spines, or birds perched on them. Most of all, Enjoy the trip!

Cacti are great subject matter. You are only limited by your own imagination.

What species of cactus? I live in Tucson (this time of year) and am about 6 miles from Saguaro National Park. I suggest that you wander into the desert during the golden hour and see what captures your imagination. Lots of species are blooming now; however, some only bloom at night. A bit of advice: Wear long pants and sturdy shoes with dense soles. Watch where you step (we have lots of poisonous snakes and other nasty critters). And... keep your distance from the Teddy Bear Cholla!

Explore low angle views that make the cactus plant appear both intimidating and majestic.

No problem. I'm sure you don't need a bunch of strangers to tell you how to be creative.

Here is one I took many years ago with an inexpensive Nikon Coolpix L16. Cactus can be fascinating subjects. You just have to really look at them.

What kind of cactus? When you get here you will be amazed at how many types of cactus there are. I love getting up close to the teddy bear cholla and focusing on an individual set of spines (be careful as they are nasty little pricks). The saguaro attract birds so watch for dove, owls, etc on them. They are great subjects at sunrise or sunset, particularly if you underexpose your shot a bit. They are the cactus that most people associate with AZ. A moonrise or set can be beautiful behind a giant saguaro. All of the cactus around here attract animals (some you definately want to keep your distance from) so be aware as you hike around. As with most outdoor scenic shots, the mid day sun is not too good for photography unless you want to expose (pun intended) the harshness of the environment. Be aware of EVERYTHING around you. I was once nearly struck by a rattlesnake because I was intent on getting a close up of a rabbit and wasn't paying attention to anything else around me. Be inventive....it is possible to shoot several different types of cactus in a single frame. And again, be careful as you wander around. As is said around here, everything in the desert sticks, stabs, pokes, bites, stings, or jabs you. But to the patient photographer, it is a beautiful place. There are as many ways to shoot a cactus as you are willing to think of and take the time for. Enjoy your visit.

I live in Tucson and this is a favorite subject for me. Shoot in the early morning when the cactus is backlit, cholla really stands out. Saguaro with interesting vistas behind them. Shoot sunsets through the Saguaros.

Thumb through some Arizona Highways magazines, (especially earlier editions in black and white). Go to capturemyarizona.com, (amateur posting site). Wildflowers might be blooming when you are here. Arizona Sonora Desert Museum near Tucson. Phoenix Botanical Gardens. Boyce Thompson Arboretum near Superior. Organ Pipe Cactus Park National Monument near Ajo. (sounds like ah ho, long a). Saguaro National Park east of Tucson. Go north or east of Phoenix to slightly higher elevations, especially for Saguaro and agave. A bit early for blooms.

Try getting down low with wide angle. Near dawn or dusk with back light, the needles glow. Marco of just about everything.

Too many things, not enuf time. Enjoy.

Go to Havasupai sometime. (Eleven mile walk or mule ride or by Helicopter. Pretty much camping only. BUT YOU WILL NEVER FORGET THE TRIP.
