Color, contrast and brightness Review

 

Color, Contrast and Brightness
Some of the most common forms of image editing include cropping (already mentioned on this page here) and changing brightness, contrast and color levels. Image editing opens up many possibilities for the digital photographer.

This is an example of some basic editing of a digital image. Before starting this type of editing on your computer, you will need to have the color on your monitor as accurate as possible.

In this example I will start with an image that was taken under cloudy conditions. The image has no shadows, which is great, the clouds however have created a dull looking image. Also the blue areas in the image are inconsistent with the blue in the other images taken on the day.

This is the original image, although the day was generally clear, there were clouds covering the sun at the time the shot was taken and the flash did not have the range to light up the image and therefore was not used.

I am using Adobe Photoshop 6 to edit this image, many digital cameras come with software that is capable of doing what I am going to do this image.

Firstly I will select the Brightness/ Contrast control.

Now I will increase the brightness and the contrast by a small amount, making sure not to brighten the image up to the point where it looks unnatural or grainy. It’s a good idea to look at the effect that the adjustment has on all parts of the image. Increasing the brightness will brighten up the dull areas and also the bright areas of the image,

Cropping Images Review

Cropping an image means to cut out a section of the image which in turn reduces the resolution of the image. Rather than reducing the resolution of the whole image, a section of the image is instead cut, or cropped, and a new, smaller image that is focused on a certain area of the image is created. One advantage of having a camera with 2 or 3 million pixels is that because the image is larger to begin with (a higher resolution), it is possible to crop a section of the image and still retain enough resolution to allow the image to be used and even printed. Some digital cameras have what is known as digital zoom. Digital zoom is essentially another name for cropping the image and the same basic process is used.Starting with a much higher resolution original image allowed me to crop the interesting part of this picture while avoiding the power lines and the underexposed sections on the image. The brightness and contrast of the image has also been increased slightly.

This is a very good compact camera that operates with ease. It is very simple to use and follow the directions. I would highly reccommend buying the accesory pack for this camera. This will give you a info-lithium battery with charger and camera case. A 32 MB chip is a must also. The 4MB chip supplied is way to small for the camera. The software supplied is very good also.

Digital camera advantages Review

 

What is a digital camera and what are the advantages of owning one?

 

Digital cameras don’t use film, instead they record images on an electric light sensor (CCD), which is made up of millions of tiny points called Pixels. The CCD “sees” what a frame of film in a traditional camera sees through the lens with the shutter open. The light collected by the CCD is then converted into data and this data is then stored on the camera’s memory card. The image can then be viewed on the camera’s display screen, downloaded onto a computer, edited, stored and also printed in photographic quality.

There is no need to buy additional memory to take more photos as you can reuse the same memory over and over again, just as you do with the memory in your computer. You can also view the image you have just taken and if you’re not happy with it you can delete it, leaving space for another one. Once an image is downloaded from the camera to the computer, it is then possible to use image editing software, included with most digital cameras, to adjust brightness, contrast, color levels, sharpen images and even apply special effects. The images can be sent to friends via email, uploaded to websites for public viewing and printed in the same photographic quality that you would obtain from a traditional film camera.

Epson Photo PC 3000Z Review

The Epson PhotoPC 3000Z provides you with all the tools you need to create memorable, lasting images. Picture quality is superb–with Epson’s proprietary HyPict interpolation/compression scheme, the camera’s already impressive 2,048 x 1,536 (3.3-megapixel) resolution is bumped up to 2,544 x 1,904 (4.8 megapixels).

The 3000Z can store images in uncompressed TIFF format, and features three levels of JPEG compression. The 3x optical zoom takes you right into the action, helping you to capture great close-ups. The camera has shooting modes for a wide variety of situations. Macro mode allows extreme close-up photography, from 2.4 to 20 inches. The continuous shooting mode enables you to take pictures at 1.4, 1.5, and 1.6 frames per second for 41, 7, and 3 consecutive shots (depending upon image quality). In interval shooting mode, the camera wakes to take shots at a user-specified interval between 10 seconds and 24 hours and then goes back to sleep.

The 3000Z also offers a movie mode, which records up to 25 seconds of 15 fps 320 x 240 video as a QuickTime movie. Most of the camera’s settings are manually adjustable, from shutter speed and aperture to exposure compensation and white balance. Focus is one of the few functions that can’t be set manually. You can view your images on a television using the video port and included cable.

Fuji Finepix 1400 User Review Review

This is the first digital camera that I’ve purchased, and I am very pleased with it. It comes with most of the features that any novice would want, yet it still quite easy to use. It didn’t even take me an hour to become familiar with it. Also, because it supports USB, you can transfer your pictures into you computer in a second or two.

The picture quality isn’t going to knock your socks off, but it’s fair. In addition, this was one of the only entry level digicams that I found which had an optical zoom. Unfortunately, the camera only comes with a 4MB card. At the highest resolution, it can only store about 12 pictures. I recommend buying an 8MB or 16MB card. Overall, this is a great, affordable entry level camera.

Fuji FinePix 4700 Review

The Fuji FinePix 4700 digital camera delivers high-end features in a camera body that fits in the palm of your hand. With the 3x optical zoom capability, it provides you with a wide range of shooting options, from telephoto to wide angle, with coverage equivalent to a 36-108mm range in a 35mm camera. The lens is fully retractable with a built-in cover to protect it from damage.

The FinePix 4700 also offers 3.75x digital zoom to bring you 11.25 times closer to your subjects. The FinePix 4700 Super CCD (charge-coupled device for image capturing) is 0.59 inches with 2.4 million pixels, producing shots at up to 2,400 x 1,800 resolution. This allows it to realistically depict objects and reproduce colors as you see them without sacrificing speed. Start-up takes only 2 seconds, and the pause between single-frame shots can be as brief as a second. In continuous shooting mode, you can shoot every 0.2 seconds. A motion-picture recording mode lets you record and play back 320 x 240 pixel video at 10 frames per second in JPEG format for up to 80 seconds.

Fuji Finepix 4900 Review

Fuji’s FinePix 4900 is one of a new style of consumer digital cameras appearing on the market. Borrowing features from both film SLRs and point-and-shoot digital cameras, these hybrids offer an extremely potent set of features in a compact package and will undoubtedly steer even more film photographers over to digital.
The 4900 features an impressive 6x optical zoom lens plus a 3.7x digital zoom. Shots are captured on a SuperCCD sensor that generates images at resolutions of up to 2,400 x 1,800 pixels, producing photo-quality prints at sizes of 8 by 10 and beyond. By default, the camera is as easy to operate as a point-and-shoot, but virtually every function is manually controllable. Shutter-priority and aperture-priority modes are available, and the ISO, focus, white balance, and exposure compensation can all be adjusted. A pop-up flash features slow-sync, fill flash, and red-eye reduction, and a hot shoe on top of the camera allows you to use a dedicated flash unit.

Fuji has replaced the traditional optical viewfinder with a camcorder-style electronic viewfinder (EVF)–a tiny LCD display inside the eyepiece. The benefits of this arrangement are obvious: the EVF provides a traditional SLR-style through-the-lens viewing experience, works well even in bright sunlight, lets you hold the camera in the more stable, traditional position, and helps to extend battery life. However, there are some situations in which the EVF is inferior to a traditional optical viewfinder: if you’re shooting in near darkness, it’s virtually impossible to see through the viewfinder, and even in brighter light, the images tend to look grainy and washed out compared to the images in the 2-inch LCD

A few things to add to the review that swayed me to the 4900 over any other digital camera was the 4900’s added feature of being able to use different lenses (wide angle in my case) with the 55 mm adapter ring. With this one can add a wide array of lenses and filters comparable to any 35 mm camera.
The camera also has a hot shoe to add a flash which I have yet to try.
My only complaint is with the rechargeable battery that comes with the camera. It doesn’t last as long as I thought it would or should but I figure I can get about 100 shots without flash and about 50 with flash (I can take a lot of pictures now without worrying about the price of film and developing).
I have found the picture quality has exceeded my expectations and I am very, very satisfied with the 4900.
It is an expensive camera but if your looking for a digital alternative to a 35 mm with all regular 35 mm settings , capabilities and quality, this IS the one!!
