Shooting Tack-Sharp Images
I. Shutter speed - Shutter speed is probably the first thing most of us think about when shooting tack-sharp images. Our first lessons in SLR photography are how camera shake and movement can ruin a picture if your shutter speed is too low. For more information on shutter speed and what your minimum shutter speed should be, check out our article Shutter Speed Guideline – The Reciprocal Rule.
II. ISO - The second thing that may come to your mind is your ISO setting. While ISO speeds up the process in which your film/sensor absorbs light, it also adds grain to your image. This grain destroys detail/sharpness in the image. The higher your ISO setting, the more detail is destroyed. New professional DSLR cameras such as the Nikon D700 and the Canon 5d Mark II (and higher models) can shoot at much higher ISO settings while retaining much of the image detail. However, with the proper lighting, it is usually best practice to shoot at the lowest ISO setting possible.
III. Lens quality - The quality of the "glass" (lens) contributes to image sharpness, contrast and saturation. For the most part, professional series Nikon and Canon lenses produce sharper images than cheaper lens models or third party lens manufacturers. However, this generalization does not apply to all lenses, and some tests for select lenses have claimed better overall sharpness from third party manufacturers than their Nikon or Canon counterparts. Does this mean you should buy third party glass? Usage and budget are important factors; but keep in mind that cheap glass, in general, will already put you at a disadvantage when trying to create tack-sharp images.
IV. Image area - In composing your shots, keep in mind that different areas of the image will be softer (less sharp) than others. The center of your frame will always be your sharpest point, while the image will only get softer as you continue to the edge of the frame. While shooting your subject off-center for composition purposes is often necessary, it isn't in your best interest to compose shots carelessly because you are relying on cropping the image down in post production. In general, areas away from the center will be less sharp relative to the center at wider apertures (F1.4, F2.8, etc), while areas away from the center will have similar sharpness as the center at smaller apertures (F8, F11, etc).
V. Aperture setting - Aperture is probably the last thing you would think of when it comes to obtaining tack-sharp images. However, it is one of the largest determining factors of shooting tack-sharp images. We all know that aperture controls your depth of field. However, did you know that shooting the exact same shot with the exact same focal point will yield different levels of sharpness on your focal point at different apertures? For example, if I focus on the nose of a face at F1.4 and with the exact same exposure value and composition, shoot the same face at F4.0, the nose will actually be sharper in the image shot at F4.0. This is simply because each lens has a "sweet spot."
Shooting at your lenses sweet spot will improve sharpness, contrast and saturation. Now you may be thinking, "well how do I find the sweet spot on my lens?" There are several rules of thumb, but the most prevalent is that your sweet spot is around 2 full stops above your lens' minimum (widest) aperture. Depending on the lens, this will be in the range of F4-F11 or so. Keep in mind though, raising your aperture too high (small) will result in aperture diffraction, another phenomenon that will reduce overall clarity. For more information on diffraction, read our article Avoiding Aperture Diffraction.
One last thing, before you go shooting all of your images at your "optimal aperture" setting. Keep in mind that composition always rules! If blurring the background to make the subject "pop" is part of your look and composition, then shoot the lowest aperture possible! A well exposed composition shot at F1.4 will still be plenty sharp for any purpose, it just may not be considered "perfectly tack-sharp." However, we should always think of composition first, and when appropriate keep your aperture within its sweet spot.
Last but not least, Digital Photography Review has an amazing widget that allows you to check out the sweet spot on pretty much any lens.

Barbados Green Monkeys
These green monkeys are so cute and do they ever loooove mangoes. I have a huge mango tree in our backyard guarded from two-legged thieves by a large Akita dog.
However she is no match for tree swinging four-legged green monkey thieves. The whole family comes (daddy monkey, mummy monkey with baby clinging on underneath and some toddler monkeys) making their way across an open lot tightrope walking on the power cables and then leaping into the tree.
They come at breakfast and tea-time to feast on our fruit, choosing the nicest ones, taking one/two bites and then dropping the half-eaten rest into our garden sending our poor dog into a frenzy.
Actually the dog too is quite fond of mangoes so my husband and I can only get mangoes late in the season when both sets of animals have had their fill!

Sea Island Cotton
http://www.coastcaribbeanimages.com/photographs.cfm?PageAction=Details&PhotoID=8772
Caroline Sameul recently captured and submitted some lovely pictures of the local Barbados cotton found growing as a shrub in the St. Joseph area of Barbados. Of course this is not uncommon in the tropics but it is amazing that cotton is something we use every day, yet we hardly think about where it comes from. Cotton is a soft, staple fiber that grows in a form known as a boll around the seeds of the cotton plant Gossypium, a shrub native to tropical and subtropical regions around the world, including the India and Africa. The fiber most often is spun into yarn or thread and used to make a soft, breathable textile which is the most widely used natural-fiber cloth in clothing today.

vibrant underwater photography by Lucy Agace
Underwater imaging is considered an especially challenging area of photography, since it requires very specialized equipment and techniques to be successful. Despite these challenges, it offers the possibility of many exciting and rare photographic opportunities. Lucy has captured unique moments of the golden tail eel and arrow crab side by side. In addition to the vibrant colours and contrasts of the different reef and sea urchin. This last submission has some breathtaking imagery of an orange sea horse close up, as well as pink shrimp in anemone and the wonderful face of a spotted eel that it appears it is staring right at the photographer.
