I’ve just tested the Tamron 18-250mm f/3.5-6.3 lens on my Canon EOS 7D camera and now I am writing this Tamron 18-250 review to give you the result.
This lens is also available for Nikon (with built in motor), Pentax, and Sony cameras. Tamron also made an upgraded version of this lens, called the 18-270mm VC for Canon and Nikon DSLR.

This lens is an upgraded version of the Tamron 18-200mm lens. If you have read my Tamron 18-200 review previously, you know that I recommend that lens for a budget super zoom lens.

This new lens is a bit different compared to the previous one. The build quality and finish of the lens clearly reflects the update. This lens now feels more solid and sturdy when compared to the old version of this lens.

In terms of optical quality, it seems that they are still sticking to their old 18-200mm formula. I found very minor difference between the two lenses in terms of optical quality.

The zoom ring is updated in this lens. It feels more solid and has a zoom lock mechanism to prevent zoom creep. This makes it easier to transport the lens. Many travel photographers will find this function helpful to have during their vacation.

Just like the old version, I found the autofocus fast but a bit on the noisy side. During the review, I find it hard to photograph discreetly. This might be a bit of a downside if you are into street photography.

Also, the small aperture at the telephoto end makes the autofocus hunt in low light. There is a simple solution for this: switch to manual focus. It will take time to get used to, but it will be worth the effort.

In terms of cost, it is more expensive than the 18-200mm. If you are looking for a budget super zoom lens, the Tamron 18-200mm lens is still the best option.

In terms of optical quality, this lens has low chromatic aberration and vignetting. However, I found the barrel distortion to be rather high. Note that all of those can easily be corrected during post processing using any software.

In conclusion, this lens is fine for general photography and travel photography. This can also be a fun to use lens for any professional photographers to use.
However, keep in mind that this is not a professional lens, so do not expect professional performance from it.

Men and women alike have a proclivity for jewelry. Especially in a country like India where each state and each region has its own different style of jewelry. Looking at the fondness of people (especially Indians) to buy jewelry, many entrepreneurs have started selling jewelry on World Wide Web. Buying jewelry has always been considered best to be done by physically checking out the item. So how can these websites promote their product?

There are various practices, business and web based, one can apply to promote sales online. Business practices include giving guarantee of genuineness of the product, giving time based warranties, having the facility of returning the product if not found satisfactory, assurance of money back etc. web based practices include having a well-designed website which is interactive, easy to download, easy to navigate and understand and also making use of jewelry photography. Jewelry photography is a challenge for even experienced photographers as jewelry tends to reflect 99% of the light it gets. It is very necessary to have perfect lighting, non-reflective surfaces and to switch off the flash.
Important elements of jewelry photography

There are certain key elements to be kept in mind while photographing jewelry; these are:

* Continuous natural daylight lighting:
To evenly reproduce the colors in jewelry and not to end up with glares and hot shot if shot with flash.

* Diffused lighting:
To eliminate shadows and hard spots and reflections.

* White Balance adjustment:
To adapt your camera to the lighting environment used to photograph and not to be misunderstood as having a white balance.

* Depth of Field & Focus:
To get a sharp, focused and clear image.

* Shutter Speed/Exposure time:
To control the lightness and darkness of your image.

* Stable camera mounting (tripod):
To ensure proper use of tripod and that your camera is stable to avoid a blurred photo

Types of jewelry and how to photograph them

Just clicking a piece of jewelry does not complete a job of jewelry photographer. Each type of jewelry, be it white gold, silver, platinum or precious and semi-precious stones, have a certain way to be clicked which will yield best results. Based on jewelry type here are certain tips to be kept in mind while clicking them.

* White gold, silver and platinum jewelry
White gold, silver and platinum jewelry tend to reflect more due to their natural properties. Silver is a natural mirror and reflects almost all of the light thrown on it. Few factors ought to be taken into consideration while doing a jewelry photography shoot of this type.

* Avoid white background: white background makes this type of jewelry appear dull and unnatural. Such type of jewelry should be photographed using dark backgrounds.
* Dark backdrops: more and more dark with a tinge metallic backdrops should be put to use while photographing such type of jewelry as the dark background is in contrast to the jewelry and it creates a three-dimensional look.
* Use lightbox: In order to deliver accurate lighting and reflections in silver jewelry photographs, you need to have a diffused lighting source within a closed environment.
* Expecting reflection free photographs is a futile effort: expecting reflection free photographs is impossible as silver, white gold and platinum are natural reflectors. All jewelry photographs of such type of metals are clicked with the reflection of either camera lens or their own reflections. The jewelry photographers make extensive use of editing software to make these photographs reflection free. They also make use of diffused lighting and enclosed lighting systems.
* Precious and semi-precious stones

While photographing jewelry with precious and semiprecious stones photographers seldom use fluorescent lights. Generally halogen lighting is used as it provides a warm light environment providing with an optimum view for stones such as rubies, pearls, opals, amethysts, and emeralds. It is not necessary that all such stones should be clicked using halogen lighting, the photographer should try shooting these stones under both fluorescent and halogen lights and compare the results. Whichever gives better result should be chosen. Proper care should also be taken to adjust camera’s white balance to the lighting to get better photographs.

Other aspects of jewelry photography
Besides taking precautions for the type of jewelry and lighting, white balance there are certain other aspects to be kept in mind while photographing jewelry, they are:

* Position of the jewelry
Correct positioning of the jewelry is essential to get a professional jewelry photograph. When shooting photographs, the jewelry photographer has to remember that the customer wants to get the best shot possible of their jewelry, as the photographs are the ones that are looked at and judged, rather than the actual jewelry. Thus, ensuring jewelry photography is done from correct angles and perspectives are the key to successful shots.

There are many accessories such as ring stand, watch stand and pendant stand that one can use to hold jewelry items while photographing them. Deciding which ones to use depends on the type of photograph the client wants, or simply the photographer’s preference. Jewelry accessories can help one to position earrings, pendants, rings, diamonds, loose stones, and other jewelry pieces in varied angles and positions, in order to capture them from the desired perspective.

* Make the jewelry sparkle

Diamonds and precious gems at jewelry stores do not sparkle as intensely as under the sun. While the sparkle is needed with the assistance of halogen, and fluorescent lighting, it could be illuminated better.

New technological advancement has created a distinct opportunity for the jewelry photography business. A scientific breakthrough in light-emitting diodes (LED) has produced lighting that matches the full spectrum of the sun. As a result, jewelry can now be displayed with maximum radiant potential.

* Cleaning the jewelry

High polished jewelry can easily get dirty with the simple touch of fingers – which usually leaves fingerprints, or from the dust in the surroundings. Today’s digital cameras can capture even the most insignificant details found in the jewelry, including dust and fingerprints. Therefore, it is important that jewelry should be cleaned thoroughly before jewelry photographer clicks them. Here are certain tips to clean the jewelry:

* Wear gloves while handling jewelry
* Make use of gem brush to brush the jewelry
* Use specialized jewelry cleaning liquid.

Jewels as a subject for photography is a challenge even for experienced photographers as so many minutest details are needed to be kept in mind while photographing like reflections, shadows, lighting areas, cleanliness of jewels etc. if there are stones in the jewelry it makes the task even harder. Although it is a tough task but not impossible if certain things discussed in the article are taken into consideration.

Photography enthusiasts will be able to dive beneath the surface of the Indian Ocean as LUX* Maldives launches the first Underwater Festival from 14th and 20th May, 2012.

D product photography is captured special photography equipment and software. Firstly; items are photographed by revolving camera, which captures the item from every single angle in case of 3D or round horizontal axes in case of 360 photography. The photos can be also taken by rotating item in front of steady camera and the whole process of capturing the images is controlled directly from the PC. Once you have series of photos in your PC, the second step is subsequent conversion of pictures into 3D or 360 presentation. There are more possible solutions of conversion “” but the most frequent are these two types of solutions; the Client-Server (On-Line) Solution or Stand-Alone (Off-Line) Solution. After the selection of the suitable viewer of your 3D presentations and uploading source images on a server, the final implementation is finished almost immediately. All the 3D viewers” windows have possibilities of customizing its size, background, borders, graphic details and many other features which enhance the graphic attractiveness of the images. The 360 degree or 3D product photography fit your websites perfectly and improves the general graphic appearance of your e-shop.

This new interactive way oft photography offers possibility of detailed product examination which may eventually avoid subsequent complaints or goods returns..

Flashlight photography is an emerging technique being pursued by photographers. Using a flashlight in photography allows a photographer a new avenue of imagination and creativity for the photographer. When used correctly, LED flashlights can mimic natural lights and create effects not possible in photo imagining and manipulation software. LED lights allow the light source to be directly controlled by the photographer’s vision. The following are some basic equipment tips and techniques.
The Right Camera
The single-lens reflex camera, or SLR, uses a mirror to accurately reflect to the photographer the same scene that the camera does. The digital SLR, or D-SLR, has the same capabilities as the film SLR, but uses a memory card instead of film. Either type of camera is great for flashlight photography because you can adjust the shutter to a long speed, which is perfect for LED light techniques.
LED Light Tips and Techniques
It is helpful to use a lot of LED lights to get a good quality picture. LED lights tend to be on the small side, and don’t give off a whole lot of light. But don’t worry – LED lights are fairly cheap and you can get dozens of them for just a dollar or so.
LED lights are wonderful hard lighting sources, because the light of LED flashlights is extremely focused. A photographer can use the LED flashlights by placing one or more flat on the ground in order to light up the bottom of an object or some other specific focal object. If you need LED lighting going upward, stack LED lights on top of each other in tripod fashion.
Another way to use LED flashlights is to use self-adhesive Velcro to make a hook strap that wraps around the lens of your camera. Allow two extra centimeters slack for attaching some loop Velcro. Connect the loop side to the hook side with the adhesive side facing outwards. Next, attach the LED lights to the adhesive side one at a time until you cover the entire strap, and voila! You now have your very own LED lighting source for pointing LED light directly at objects, and you hardly spent a dime.
Natural Photography and LED Lights
Combining LED lights with other flashlights, natural light or camera lights can achieve interesting experimental effects. Try using a flashlight held in front of your camera flash with no direct sunlight. The combined lights can add a natural warmness to your photo, making your photo interesting and unique. Another experiment is using different white balances through different colored gels or color filters in front of white LED lights. This technique can simulate several white balances of natural light. LED lights can also be used to “paint” light across an image by using a slow shutter speed and sweeping the LED flashlight across the scene.
Using macro techniques, where the lens to subject distance is much closer than usual, LED flashlights allow the photographer to mimic and/or enhance night shots. This method can allow an aesthetic white balance in spot lighting photography sessions.
