Closeup digital nature photography is the practice of taking photograph pictures where the image capture by the digital camera would be a life-sized or larger when printed on a standard "4x6 inch" print.

There are many potential something that needed to be use as a subject or an object for this type of photography in nature. Taking some time to find the right subject or an object would not only produce good and great photos, it might also change the whole way you really look at the world around you. The image result as a result of you get from the closeup digital nature photograph is a pictorial representation of the olden days' phrase "stop and smell the roses".

Furthermore, the most exciting and interesting part of closeup digital nature photography is finding interesting subjects or objects. Flowers and houses are popular among the photographers, just as the insects and other animals like the pupils and cats. And these mostly look pretty good and good to look at most of the time, since there are many more gift and elements of nature that could be photographed and that would look pretty good and beautiful.

If you are to take a walk down the street and look around, you are to notice and bound to come around so many beautiful and nice things you have never seen or spend time to look at before, and this would look nice too when taking as closeup digital nature photography.

The most important thing to be considered about the piece of equipment when taking the closeup digital nature photography is its capturing lens. There are some special and unique lens that are there on sale at the market and several alternative scope and techniques for getting a high quality closeup digital nature photographs.

Photograph the accordion like underside of the mushrooms growing in your front lawn or the texture of a leaf hanging on the tree in the yard. The grain on the cut end of a wooden fence also begs to have a closeup taken of it. Take time to "stop and smell the roses" and you will begin to see the world of nature as a bountiful opportunity for closeup digital nature photography.

Apart from buying a special lens, use of extension tubes , reversing your lens and using a bellows attachment are all good and very productive options.

Learn How to Succeed With the Most Difficult Task in Jewelry Photography

Managing the challenge of narrow depth of field in highly reflective surface environment

By Avi Roth

In the field of commercial photography, be it in motion or static, every category presents a challenge of its own. With jewelry photography, an object of highly reflective surface (HRS), the challenge is amplified due to its relatively small size captured mostly in close-up environment with shallow depth of field, surface complexity (specular), and limited ways of lighting due to space restriction between the lens and the object. Jewelry photography demands knowledge and experience to overcome the compounded difficulty of controlling reflections and limited depth-of-field (perceived sharpness) in close-up jewelry photography.

In addition to the problems mentioned above, the success of reproducing and obtaining a high quality digital image of jewelry will depend on the equipment used in the reproduction process. There are basically three types of camera systems one can employ:

a. Digital SLRs like Canon, Nikon, Olympus, Sigma with good sensor resolution (6-14 MP)

b. Medium format cameras like Hassleblad, Rollei or Mamiya with a larger sensor digital back (11-39 MP)

c. Large format view cameras like Sinar or Toyo with live video studio solution (11-39 MP)

The purpose of this article is to discuss some of the principal challenges posed by the complexities of reflective surface reproduction, particularly in digital close-up photography. Below I will present some solution to these challenges from the lessons learned and experienced in my daily practice and from my own research as to what is the best, fastest, and simplest solution to an otherwise complex assignment of jewelry photography.

Jewelry surface (HRS)

The most difficult task of all HRS digital captures is jewelry. In essence all jewelry objects are built with reflective qualities of various degrees and can be compared to mirrors. Mirrors are objects with good specular or diffused reflection; that is, image forming qualities. Imagine pointing your lens towards a mirror at a close distance. What will you see? Exactly, yourself holding a camera and your surrounding area. Jewelry objects in essence embody three kinds of mirrors: flat, convex and concave determined at random by the jewelry’s very shape. Curved mirrors magnify or shrink images therefore distort the reflected image. Most jewelry objects typify spherical mirrors structured in an interesting relationship of concave and convex surfaces.

Solutions:

Understanding the basic reflective properties of mirrors can be helpful in solving some basic problems related to jewelry photography because of their common reflective properties.

a. Jewelry reflection has no physical existence. Conceal the camera or choose a shooting angle for the jewelry to reflect a controlled surface such as a white board or soft box.

b. The location of the camera/lens matters in terms of how and what will the jewelry reflect. Use longer lenses to extend the working space between object and lens.

c. When light strikes the jewelry surface the angle of reflection equals the angle of in incidence. Place your light source indirectly to the angle of reflectance.

d. The reflection on the jewelry is half the size of the reflected image - the jewelry is always halfway between the reflected image and the reflection. Creating and placing the jewelry inside a large soft tent enables the application of various light sources to minimize and control unwanted reflections.

e. If the jewelry surface is flat and perfectly shiny, specular reflection will result. If the surface is rough, diffused or distorted reflection will result (bending) Place the jewelry in a light zone of several loosely arranged large white panels, and by modifying their position relevant to the object will enable the control of light source there by controlling unwanted reflection.

Overall Sharpness:

A narrow depth-of-field (DOF) can create spectacular effects when photographing insects, flowers, etc., but in jewelry photography if the entire image does not appear in full focus, the image becomes an unusable one. Unusable in the sense that some parts of a ring or bracelet needed to provide useful data for the purpose of presentation will be unacceptably less sharp than other parts. For example, the front part of a bracelet (focal plane of the lens) is in sharp focus; but as we move towards the back region the loss of sharpness becomes unacceptable (blurred). DOF and image sharpness changes with sensor size. Smaller digital sensors obtain maximum sharpness at wider apertures (f:8-f:11) while larger ones at (f:11-f:22). Capturing small objects like jewelry via close-up photography presents a problem since only a very narrow portion of the object relative to the focal plane will be acceptably in focus. One way to extend depth of field would be to take images using a narrow lens aperture. This solution has a serious disadvantage. Small apertures bring more light diffraction, degrading the image resolution. This is one reason why many consumer digital cameras (with very small sensors) won't let you stop down past f:8, while studio solution sensors are often stopped down to f:32 and beyond.

Solution:

The application of double exposure solution or photo stitching in jewelry photography partially solves the limitations of shallow depth-of-field. The technique known as "focus stacking" is another. Using double exposure when limited depth-of-field is available is a powerful technique to help photograph and present jewelry.

Depth-of-field determines what part of the jewelry has the sharpest focus and its amount. Unfortunately, at larger apertures depth of field limits attention to a particular focal points i.e. the top of a ring, while minimizing details at the shank. A greater depth-of-field would presents all the elements of a ring sharp at once, relatively equally. Depth-of-field is determined by the following: lens aperture (ƒ-stop), lens focal length and your distance from the focal point. In jewelry photography, of these three the aperture has the most influence and the least modifiable. Therefore to increase depth-of-field and achieve total sharpness over the entire image, move farther away from the jewelry by using a longer lens.

1. Capture two images, first focus slightly below the ring top, then a second focused lower at the center.

2. Bring both images into two separate layers in Photoshop to combine the two into one sharp image.

There are of course other solutions such as the Helicon Focus. This program is designed to manage the shallow depth-of-field problem in close-up imaging. It also aligns the images that change their size and position from shot to shot. This function is especially important with close–up jewelry photography.

However, the most pragmatic answer to the depth-of-field challenge is the large format studio camera. These cameras such as Arca Swiss, Linhof, Sinar, Fuji, Calumet or Toyo have expandable bellows, tilt and swing capabilities, and are allowing the capture of high-quality images with extended depth-of-field beyond the optical limitations of the lens.

Hello my tech frnd..could u help me out frm viuses..detail bellow?

i hve win2000 professional OS in my PC . yesterday a porn site opned when i was surfing on net..and i am seeing some .exe files in location of "cwinntsystem32" the files lke this...CACLS,DEBUG, CIPHER, COMP, COMMAND, CHKNV,, DISKCOMP, CLSPACK, DFRGFAT, DEFRGNTFS, DDMPRXY, ETC... PLZ CAN U TELL THESE files are viruese...if yes..then can i remove frm deleting those files..

I have a legal and moral obligation to keep my pc 100% clean. And I use an antivirus/spyware program out of Beijing, China.
http://www.filseclab.com -- This program has kept me 100% clean for the past nine years.
Twister Anti-Trojan Virus is absolute state of the art technology that has a real time scanner
that really works. Will scan your memory on start up and continues to run in the background
while you use your pc. Plus this software uses very little CPU resources.
Some examples of how great this program is. If you open a webpage and there is a virus or
spyware embedded in the webpage the scanner will catch the virus in a second and clean.
If you download any type of file including music or a zip file and there is hidden embedded
virus in the file the download will stop and the Twister will clean and stop the download.
I had an experience where the software I download the company used another installer other
then their own. The installer had hidden embedded virus in the installer program.Twister found it and cleaned, plus ended the installation and traced it back to the installer software.
(I wrote the original software company and they now use their own installer).
What is really great is that you only pay a small one time fee for life. You will get frequent
large signature updates,excellent support and they never charge you for any new versions.
There are many other features as auto downloads, and the ability to fix all type of problems with your registry or windows.
The chinese don't believe in the annual fee or paying of new versions like most of the other software companies want to be paid over and over for the original purchase.

I use Zone Alarm free firewall (http://www.zonealarm.com). As a backup even though I have ADSL.I use ewido antispyware / malware. www.grisoft.com --Ewido was purchased by AVG. Ewido is free and will protect you from rogue dialers.
