Capture The Perfect Flower Macro

by Natalie Johnson


If you appreciate the subtle beauty of a freshly bloomed bud or want to preserve the memory of that bright and bold gift bouquet why not try putting your photography skills to good use and capture a delicate floral macro?

Begin by finding the perfect specimen and if possible place it in an area with great soft light, for example in front of a window that is shielded with a sheet or net curtain. If the plant is outside either move it to a shaded location or find a way of diffusing the sun’s rays with a piece of fine material if the light is particular harsh or the sun is at a high position in the sky. Shoot with your back to the light (without blocking it) or from the side, so that the light falls gently and delicately on the flower head’s crevices and petals, effortlessly eventuating texture, colour and the intrinsic detailing. An overcast but bright day will undoubtedly harvest optimum captures, but if you need to ‘add’ extra light utilise a reflector to lift details from the shadows.

Next set the camera onto a tripod or if you are lacking one try using something as a stable substitute to support it underneath. Using something like

will be extremely useful here, especially when shooting immoveable or smaller specimens as the accessory is relatively dainty and low to the ground as it doesn’t have a restrictive centre column like a tripod does.

In terms of glassware a macro lens or extension tube will reap stronger images, otherwise experiment with focal length you have at your disposal and use your distance to influence the composition, determine how close you can get to secure a lock. Some people prefer the simplicity of auto-focus, whereas others surmise that manual offers greater creative control, either way decide what you want in focus, lock on to it and then recompose.

If you are using a point-and-shoot device, opt for the camera’s macro mode and ensure that the flash is deactivated. DSLR or hybrid users should switch into Aperture priority and experiment with the lens’ aperture range to alter how much detail is captured. For a crisp centre and softly blurred petals or background opt for an aperture of between f1.8 and f4 depending on the strength and range of the effect you want to generate. If you’d rather keep the flower head’s details crisp use a narrower aperture such as f18 or even f22.Depending on the colour of the flower you may find you’ll need to employ exposure compensation to balance the scene.

Stand above the flower and shoot the subject from various angles, then lower the lens in stages to the same level as the flower and shoot again, finally fall beneath the flower head and shoot up at its delicate underbelly.
Review your captures onscreen to determine what appeals to you or what you would like to develop. If you want to tweak the captures in an editing suite it is advisable to shoot in RAW so all of those vivid details and colours are naturally replicated.

If you would like to repeat the photo session at a later date, try experimenting with various lighting techniques, lenses, gels and include elements such as water for that heightened level of interest. Shooting a flower macro just after it has rained, or before snow or frost melts, can really exaggerate the specimen’s beauty and lends itself to creating a more dramatic photograph.

Tripods - When Do You Need One?

Tripods - When Do You Need One? 
 
By Sheila Crosby
 
With very rare exceptions, the main subject of your photograph must
be sharp - not necessarily the whole picture, but certainly the
subject. Even if you want the subject blurred, to give a sense of
movement, then the background must be sharp. And you'll get the
sharpest photographs by using a tripod.

There are three ways your photo can be unsharp: either the focus is
wrong, the camera moved, or the subject moved. Here's how to tell
the difference:
 
    * If something in front or behind the subject is nice and
sharp, then the problem is poor focus. For example, your baby is
blurred, but the carpet underneath is sharp.
 
    * If the background is sharp, but the subject is blurred, then
the subject moved. Sometimes you can do this on purpose to give a
sense of movement, but that's outside the scope of this article.
 
    * If everything is unsharp, then it's camera shake. Serious
camera shake will leave everything streaked in the direction you
moved the camera, usually vertically.
 
This article deals with how to avoid camera shake.
 
Most of the time, you can simply hold the camera in your hand.
Obviously, this is much quicker, and gives you time to grab a shot
of that yeti before it disappears.
 
The great disadvantage of tripods is that they slow you down.
Perhaps the clouds move while you're setting it up, or the sun
sets, or people waiting for you have time to get bored.
 
The great advantage of tripods is that they slow you down. You have
time to see the coke can in the foreground, and move it, before you
take the shot.
 
So when should you use a tripod?
 
    * The longer the focal length of the lens, and the longer the
exposure, the more time the camera has to wobble. You will need a
tripod if the shutter speed is longer than the reciprocal of the
focal length (e.g., 1/60th for a 50mm lens, or 1/500th for a 500mm
lens).
 
    * The bigger the enlargement, the more obvious any camera shake
becomes. If you're hoping to make a 24" x 16" enlargement, you need
a tripod.
 
    * If you're hoping to sell your photos for stock photography,
you need a tripod.
 
    * Macro subjects -- anything over 1/4th life size -- always
need a tripod because you're so close to your subject.
 
    * Negatives bigger than 35mm are wasted unless you use a
tripod. Besides, plate cameras are too heavy to comfortably hold by
hand.

Different tripods suit different situations.
 
    * Flimsy tripods are a waste of money. It's not a bargain if
you never use it.
 
    * Heavy tripods are fine in a studio, but not for hiking up a
mountain.
 
    * Some tripods have a hook and the bottom of the center column
so you can hang a weight there for greater stability. This is great
for taking landscape photos in a gale, but you rarely get gales in
a studio.
 
    * Some tripods open up considerably taller than others. Check
the height with and without the center column raised. (And check
the stability of the center column, too.)
 
    * Some are easier to adjust than others.
 
    * And of course prices vary widely. But bear in mind that a
tripod might well last you 25 years.
 
 
ALTERNATIVES TO TRIPODS
 
    * Monopods (Also called a unipod) These are easier to carry
around, and faster to point, but less effective. They're popular
with sports photographers, who tend to use long lenses but
obviously can't spend five minutes setting up each shot.

    * Table tripods These are small (about 6" high) and therefore
extremely portable. They're not much use for landscapes unless you
can find something to stand them on, like a rock or wall. (I once
used the speakers at a rock concert. Don't. Speakers vibrate!)

    * Clamps These are also small and portable, but you need to
find something to clamp them to. I have a combined table tripod and
clamp, and over the years it's proved very useful.

    * Beanbags You can buy photographic beanbags, or make your own
from anything that isn't so full that it's rigid. For example, you
can use an old sock half-filled with rice. You can also take an
empty sock on a hike and fill it with sand or gravel before use.
That way you don't have to carry the filling around. 
 
I use a bag of peanuts. One of these days I'll be stranded on the side of a
mountain in the mist, and I'll be very glad of those peanuts.
(Kendal Mint Cake doesn't make a good lens support.) The big
disadvantage is that you need something to put the bean bag on.
Sometimes there's a nice convenient wall, just the right place and
height -- just not very often. Sometimes you can park your car and
use the roof - sometimes. Failing that, there might be a lamppost
that you can push the camera against.

    * The car window If you haven't got the right kit, or you
haven't got time, wind the car window down to the height you
require and rest the lens on that. It's not nearly as good as a
tripod or beanbag, but it's better than holding the camera by hand.
Just remember to turn the car engine off and ask any passengers to
sit still.

 
IF YOU HAVEN'T GOT A TRIPOD
 
This is definitely second best, but it's inevitable that you'll get
caught without a tripod at least occasionally.
 
   1. Use as fast a shutter speed and as wide a lens as possible.
 
   2. If possible, get into position to use yourself as a tripod,
for example with your back and feet against rocks and your elbows
on your thighs. Warning: bystanders may snigger. If this isn't
possible, plant your legs a little apart, like a sailor, and tuck
your elbows into your ribs.
 
   3. Hold the camera to your eye and compose the picture.
 
   4. Take a deep breath and then breathe out.
 
   5. Squeeze the camera top and bottom to release the shutter. If
you just press from the top, the camera will move down a millimeter
or so.
 
These tips should enable you to take consistently sharper photos.

Shutter Speed Basics

Sutter Speed Dial picture
Shutter Speed for Beginners
I’m sure you know that one of the most important key elements to getting beautifully clear photos is not only shutter speed but also knowing and having a sense of the artistic. But the artistic imagination of the photographer is different from other arts; since you have to think in split-second increments. You can’t study a photo you haven’t taken yet like a painting, working on it gradually.
Shutter speed is one of the first things in digital photography that you must understand if you want to advance your skills. It can make you or break you as a digital photographer.
First, the shutter speed number refers to the speed of the rotation of the shutter inside the lens, measured in rotations per second (RPS). With photography, shutter speed is the time during which the shutter is open during the photo event to allow light to hit the film or image sensor in a digital camera. So, in combination with adjustments of the lens aperture (which is just controlling how wide the lens is), the shutter speed controls how much light the camera will record.
The basic rule is that a fast shutter speed demands a larger aperture to avoid under-exposure, while a slow shutter speed is offset by a very small aperture to avoid over-exposure. Slow shutter speeds are often used in low light conditions. Fast shutter speeds also give clarity to a moving image, and the fastest can freeze motion in mid-second.
Say you’re snapping a moving car. This example I’m talking about here involves a car on a regular street, going at a reasonable speed. To freeze the motion of the car as it passes you, you will need a shutter speed of about 1/2000. That means that the shutter has opened and closed so fast that you can’t imagine – one two-thousandth of a second. This is done a lot in sports photography, but even a simple subject like kids playing or your pet (who isn’t too good at staying perfectly still, unless they’re asleep).
But sometimes you want blur. You might want to capture the motion of a Ferris wheel, the flow of traffic in an intersection, or a subject with a surreal, dreamy, or action-oriented look. In that case, a shutter speed of less than 1/500 would be what you want. An old trick which many novice photographers use is to use ultra-slow shutter speeds to capture lightning. Go to a high space during a lightning storm at night, far away from city lights, and set up a camera with the shutter open and wait for a flash. Now close the shutter – the job is done for you by nature instead of your camera!
If possible, getting a single-lens reflex digital camera is the ideal. This will allow you to control the shutter speed alone without affecting the adjustment of the aperture.
Shutter speeds are a built-in invitation to experiment. It helps if you take several shots of your subject with different settings, noting each one on a notepad, then using your notes to compare the relative effects that each setting had.
