Advantages of SLR vedio

March 13th, 2009

Nikon D90 is the world’s first SLR camera which can record video. And then I will tell you why it is a big step in camera history.

 

One of the great advantages about having a digital SLR with video is that it can capture motion and sound when a still image just won’t tell the entire story.

I’ve taken hundreds of photos of my son dancing around the living room to music, and a few of them do capture the essence of his performance.

But there’s one thing missing: the music itself.

With the video option on the Nikon D90, I was able to grab some still images of him jumping about, and then quickly switched to video mode for full motion and sound.

Clearly, some subjects will benefit more from video capture than others (landscapes don’t DO very much).

A second benefit of capturing video with a digital SLR is somewhat less obvious.

Since you are able to change the lens on a digital SLR (something you can’t do with a standard video camera) you can capture some VERY interesting shots.

This is especially true when you use specialty lenses: extreme wide angle, extreme telephoto, or macro.

For example, with a macro lens, you’re able to get up close and personal with even the smallest subjects. Imagine being able to capture your very own nature documentary (Ants at Work) right in your backyard.

Or, maybe you’re really into surfing.

With an extreme telephoto lens attached to the camera (and a really nice tripod) you can capture the action as if you were sitting right in front of the wave.

 

Nikon’s new AF-S DX lens 35mm f/1.8G

February 23rd, 2009

It seems we are waiting for a long time,Nikon finally announced the new 35mm lens which is designed for modern cultures photo sensor (DX). This lens is

perfect for Nikon beginners camera such as Nikon D40, D60 and advanced camera like the Nikon D90, D200 and D300.

 

The focal length of 35 mm is close to full-frame 50mm camera, a classical focus for the photographer. Mechanically, this has been equipped with AF-S Silent

Wave Motor (SWM) to ensure fast and quiet AF operation.

Mounted on a camera in DX format, the fixed focal length, the rapid opening of the lens offers photographers a range similar to the focal length of 50 mm

traditional - allowing photographers to capture images at a focal length of similar to the naked eye in the field of view.

The AF-S DX NIKKOR 35mm f/1.8G is the first single focal length of a normal picture angle developed exclusively for Nikon DX format. It is compact and

lightweight, which gives the model of reproduction of high-performance single to a single focal length lens at an affordable price. This lens is most

suitable for portrait and landscape shooting.

It will be a good news for users of D40 and D60, because these cameras have lens AF-S for the operation of auto focus. Most of the old Nikon equivalent focal

length prime lenses do not have this ability AF-S.

Every coins has two sides.Unfortunately, this goal is only compatible with DX format camera, which means that the D3 or D700 owners can not use it for the

full-frame or have poor image quality particularly in the corner of the area. But this is not a big deal since just launched the new Nikkor 50mm AF-S f/1.4G

recently for full frame users, in addition, full-writers can use the old but reliable AF Nikkor 35mm f / 2.

This will be sold at $ 200, which is less expensive than most of the goals except the Nikon 50mm f/1.8 and 18-55mm VR kit lens.

Improving your photography skills

February 3rd, 2009

To be a doodg photographer,there is much to think about–the right equipment, the right angle, the best subject, etc.All you need to do to instantly improve your photography is follow these ten simple tips.

Something that can really make or break a photograph is the lighting.The golden hour is one hour after dawn and an hour before dusk.The reason for this is the sun is very low in the sky, giving a very diffuse, even light, which lights objects from the side, instead of overhead.

Consider the angle or the shot. If the emphasis is down a hillside, adjust the camera’s angle accordingly. If emphasizing height, angle the camera upward. If taking a picture of long, flat land such as a farmer’s field, make sure to position the camera to take the bulk of the field in.

If you’d really like to improve your skills as a digital photographer, why not challenge yourself with these improvement-based assignments?

The world is a cavalcade of color, why not challenge yourself to capture a fraction of the range of colors in all their magnificent splendor and awe-inspiring beauty? Change some colors while you’re at it. Why not learn to change a bluebird to red, sepia or black and white? Capture skies that are NOT blue, clouds that are not grey and the earth in several different colors of the rainbow? Can you capture rainbows in vivid detail? See the world in all its colors – or in your own.

The trick is to get the best shot possible and it can take a little practice. As long as a person can hold the camera steady and in the right place, the photographer should be fine.

Canon EOS 5D Mark II VS Nikon D700

January 8th, 2009

We are used to seeing a new models coming into the market just for several months or for longer-18 months. But this time, for Canon EOS 5D Mark II, we have been waiting for nearly 3 years! At this time, Canon didn’t disappointed all of us. It seems Canon EOS 5D Mark II is a perfect camera.

The new EOS 5D Mark II has changed most except sharing nearly the same body and AF system as its predecessor. The sensor’s been boosted to 21.1 Megapixels, matching Canon’s flagship EOS 1Ds Mark III at a fraction of the price, the maximum sensitivity increased by three stops, continuous shooting accelerated from 3 to 3.9fps, the viewfinder coverage slightly broadened to 98%, and the screen greatly improved in size and detail to a 3in VGA model. There’s now also Live View, AF micro-adjustment, support for quick UDMA cards, an HDMI port, a new battery with accurate feedback and numerous processing tricks including Highlight Tone Priority, Auto Lighting Optimizer and Peripheral Illumination Correction. And oh yes, it’s also the first Canon DSLR to offer movie recording, and in nothing less than the 1080p format.

As mentioned in my blog several time before, Nikon’s D700 is the company’s first ‘affordable’ full-frame DSLR. Compared with The Nikon D700 features quicker 5fps continuous shooting (or up to 8 with the optional battery grip), a considerably more sophisticated 51-point AF system, a popup flash, on-demand grid lines in its optical viewfinder, a virtual horizon facility and in-camera correction of chromatic aberrations. In all, both Nikon and Canon have produced stellar DSLRs at prices that we would have considered unbelievable five years ago. Nevertheless, the Canon 5D Mark II and Nikon D700 are probably the best overall DSLRs in the market in terms of cost vs. benefits.

Just as I have said, both Canon EOS 5D Mark II and Nikon D700 are the worth buying DSLRs in the market in terms of costs and benefits. So it’s hard to decide which one is better. I think all depends! Here below I listed the features of both cameras and maybe it will help:

Olympus E30 VS Canon 50D VS Nikon D90

November 24th, 2008

The price gap between the upper-entry-level Olympus E-520 and more expensive E-3 has always suggested there is room for a mid-range DSLR to sit between them. Olympus has announced the E-30, a new 12.3 megapixel Four Thirds Standard DSLR camera that is positioned between the pro E-3 and consumer E-520 models to compete with the Nikon D90, the Canon EOS 40D, and the Canon EOS 50D. It has more AF points than the 50D but less megapixels and lower color depth, a better viewfinder than the D90 but weaker ISO settings and a smaller (albeit rotating) screen. The Olympus E-30 will be available from mid-January 2009 and retail for $1300 body only. If you are interested in Olympus E-30, and feel confused between Canon50D,Nikon D90, here is a specs to help you to choose.

Nikon D90-is it worth to buy it?

November 4th, 2008

The new Nikon D90 DSLR camera has just been announced for a few weeks. It definitely will be one of the hottest selling SLR cameras this Holiday season. The new Nikon D90 is among the first D-SLRs to be able to capture high-def video, being able to capture video with any lens or any setting defined in the camera which in itself is a breakthrough change in the Digital SLR.  It offers a movie function, allowing you to shoot movies in three different motion JPEG formats: 320 x 216 pixels, 640 x 424 pixels and 1,280 x 720 pixels. Now you can capture life’s moving moments with added drama by using many of Nikon’s NIKKOR lenses, including the AF DX Fisheye 10.5mm f/2.8G ED and the Micro-NIKKOR lenses. The shallow depth of field can give your movies a more creative and emotional impact. An additional benefit is the D90 image sensor, which is much larger than a typical camcorder for higher image quality and exceptional high ISO performance during low-light shooting.

Good points:
Big Live View viewfinder and detailed screen
First DSLR with movie mode
4.5fps shooting & 11-point AF
Great handling and ergonomics
Fair Priced

The Bad:
Resolution not a big step from D80.
Remote & RAW software costs extra.
Video Recording needs lots of storage space and is limited in length to protect the CCD chip.
No Autofocus during video recording.
It is a SLR camera, therefore it does not fit in your pant pocket.

For Whom:
There’s no doubt the D90 should be short-listed by anyone shopping in its price-bracket, and should its features match your requirements, you’ll be very happy with it. Existing D80 owners should however think very carefully about whether it really offers them an upgrade, or whether stretching to the D300 – or indeed waiting – is a better bet. The Nikon D90 is a great gift for anybody who wants to seriously start taking high quality photos with SLR technology.

How and where to find cheap digital cameras online

November 3rd, 2008

The days only buying digital cameras from the retailers are gone. Now many people choose to buy them from the Web. There are many kinds of disposable cameras on the internet. There are also many sources for disposable cameras online, such as eBay, DigitalRev. So knowing where and how to find a cheap place to buy a digital camera is very important. 
 
The best place to start in your search for cheap digital SLR camera is the internet. There you can find a wide variety of cheap digital SLR cameras and many other good deals. Most of them are discountable. Just remember that a discount disposable camera may or may not have a flash, and may not have the limited perks and options that are usually offered with disposable cameras such as processing with a CD. Typically they have 27 exposures each. Apparently some companies use generic (often reused) disposable cameras — these are not as good as new unused ones. When looking , worrying too much about the exclusive features of each of the brands should not concern you too much as most of the digital SLR cameras have similar features.

For beginners in photography, it is highly recommended that you read a lot of books and take a lot of pictures before you begin your search on the internet. This will give you a good knowledge of some important things such as the lens, focus, and face detection, whether to use digital zoom or optical zoom, find out the ISO sensitivity you need for different shots along with the lighting, stabilization features, and the mega pixels you need for a particular project.

Many digital SLR cameras are as cheap as ordinary cameras. But most of these models do not come with all the key aspects like dust control and image stabilization, do not, however, disregard these cameras for those reasons as they do also produce high quality images. These are especially good for beginners.

So, when you want to buy a cheap digital camera, don’t just go for the first thing you see that is a well known name brand. First look at the specific details like the ISO sensitivity, mega pixels, zoom functions and more to make sure that you are getting the quality you want, and also be open to some relatively unknown name brands because if you find the correct specifications, you may get a cheaper camera that is still of great quality. Also look at lots of digital camera reviews and price comparisons from various online and offline sources. Then do different online shop to find the best for you.

Buying digital cameras with Dust Control

October 29th, 2008

Dust spots on your D-SLR’s sensor appear as tiny black specks on the image. When photographers change lenses, dust can enter the camera and lodge on the filter or protective glass that covers the sensor. These dust spots can show up as dark blotches in subsequent shots. A camera with Dust Control Systems will prevent dust from settling on your camera’s sensor which is exposed to the elements every time you take the lens off. This technology is only found in interchangeable-lens DSLR cameras, such as Canon 450D, Canon 50D and so on, where it is a virtual necessity.

Olympus was the first camera manufacturer to install dust-reduction technology in its DSLR cameras, with a special Supersonic Wave Filter (SSWF) system that vibrates the filter in front of the sensor to dislodge dust. The dust collects in a tray below the sensor, which is cleaned when the camera is serviced. Other manufacturers have followed with similar systems - but they may only be included in one or two models.

Some manufacturers combine the vibrating filter with anti-static materials in the camera’s mirror box, while Canon adds a Dust Delete detection/removal system via software. Only Canon’s system deals effectively with dust that becomes ‘welded on’ when a camera with dust on its sensor is moved between low and high humidity.

Listed below are a part of the latest digital SLR cameras that include dust control systems.

About Wedding Photography

October 28th, 2008

Taking professional quality wedding images is a big challenge to new photographers. Any digital SLR body combined with a decent lens (see below) is a good start. Most professional wedding photographers, however, use a set of three zoom lenses: a wide-angle zoom, a wide-to-tele zoom, and an image-stabilized telephoto zoom. Most professional wedding photographers recommend that for small sensor, Canon 40D or 50D, Nikon D90 or D300 are good ones;for Full frame cameras, they suggest Canon 5D, 5D Mark II, Nikon D700 or D3. If you are serious about photography, try to buy a DSLR. That way you will be able to purchase separate, high quality, lenses. A resolution of at least 6 megapixel is important. The flash unit is as important, if not more important than the camera. I have a really old Canon Point & Shoot digital camera - but it has an external flash shoe. With it, I can take indoor bounce-flash photos that have incredible lighting; no one would guess they come from an old digital camera. When buying a digital camera, make sure you get a quality external flash that allows you to rotate the flash head vertically and horizontally.

Camera with Image stabilization option and ability to handle high ISO is essential. Camera should be responsive and auto focus must be fast and accurate. Lenses with a large maximum aperture of f/2.8 or larger are extremely valuable for weddings. The wide-angle zoom lens makes it possible to photograph in confined spaces, such as the bride’s dressing room or a packed dance floor. The wide-to-tele lens is wide enough to take a group photograph, but still long enough to take a three-quarter portrait of a couple without the unflattering effects of wide-angle perspective distortion.

Flashes and Accessories

1. 2-3 500-800 w/s monolight heads
2. 2-3 “speedlight” on-camera TTL flashes
3. light stands for each flash
4. umbrellas/softboxes for each flash
5. flash triggering device (radio slaves, optical triggers, or PC cords)
6. hand held flash meter

Wedding photos are a challenge to take, simply because of the flurry of activities that go on and the wide variety of lighting conditions that may occur.  But do remember that while wedding photos are challenging to take, they can be very rewarding. Especially when you see the couple smiling and reminiscing about how wonderful their wedding day was.
