These days everyone seems to be a photo editing expert but it doesn’t mean that the programs for such tasks are easy to get your head around. Transforming colored images into black and white is likely to be an essential skill you’ll need to learn. This tutorial is based on GIMP a photo manipulation program which basically acts as the free version of the costly Photoshop software. I feel that this program has a far simpler interface for beginners.
Once you have retrieved the image you would like to edit from your digital cameras or the internet, your best bet for cementing these techniques is to stick on the kettle, boil yourself a tea and simply try out the different methods of achieving B&W images to see which works best.
I myself am no manipulation expert but these are the three methods I have learnt by experimenting with GIMP and my Dell laptops own editing program that came packaged with it.
Grayscale:
(Right click the image - Mode - Grayscale)
This is the most popular method for creating B&W images, though it works less well with images with low green channels (read as; less green colouring). The grayscale method supposedly mimics the human eyes sensitivity to different colours.
Desaturate:
(Right click the image - Colours - Desaturate)
Unlike Grayscale, the RBG channels in Desaturate mode are not remixed to different percentages, so different results should occur. Images transformed to B&W via this method tend to have more ‘noise’ (or blur) which can be desirable or undesirable depending on what you want for you image.
Channel mixer:
(Right click - Components - Channel Mixer - Monochrome (tick box))
Flexibility is the main attractive trait of this method. Once the monochrome box has been selected, you can trial different levels of the red, blue and green channels. Experimenting with these levels will affect the contrast and noise of the picture. Working out which percentages of each work best is all part of the fun!

Buying digital cameras for kids is a great way to teach kids about technology and help them to express their creativity. There are many models available, from digital cameras made specifically for kids to more adult styles which are suitable for older children. The model you get will be determined by the age of the child and what they will use it for. What follows are some factors to keep in mind when choosing a digital camera for your child. By the way, you should seriously check out the GoPro HERO, it is really good. Here are some GoPro HD HERO reviews.
One of the first things to consider is how easy the camera is for a child to hold, point, and carry unless you’re buying one that is especially made for young kids. Depending on the age of your child, you may want to consider getting a more adult style camera. It is important to make sure your child can properly handle any camera that you buy. It wouldn’t be good to get a bulky camera that the child won’t be able to carry around. It’s also best to choose as simple a model as possible. The more features the camera offers, the harder it will be to figure it out. In many ways, choosing a digital camera for kids is similar to choosing a starter camera for adults, with the additional consideration that it has to be easy to hold. When choosing digital cameras for kids, you have to consider your budget. While you should do this when you buy anything, a child’s preferences can and do change rapidly so it’s especially important to keep your budget in mind. If the child has no photography experience or is very young, it doesn’t make a lot of sense to spend too much on a digital camera. This is not only a risky investment, but if the camera has a lot of advanced features, your child will neither appreciate them nor know how to use them. A child will actually get more out of a simpler, lower priced digital camera that is easy to operate. Young children who have an advanced understanding of technology, though, may benefit from a more adult model of digital camera.
Among the other features you should look for in digital cameras for kids, a USB cable can be very useful. If you want to be able to share the pictures you take, print, store or put them online you’ll need this USB cord. You won’t find this feature in many toy cameras but almost every real camera will have one. No matter the age of your child they will want to be able to easily transfer pictures from one device to another. As technology advances, it’s likely that most digital cameras on the market will come with a USB cable, but it’s something you should make sure of when shopping for digital cameras for kids. You may find a camera that requires you purchase a USB separately.
There are various factors to consider when you buy a digital camera for your child. You want a camera that is well made and durable and simple enough for kids to figure it out. You can foster a lifetime love of photography when you find the right camera. As you search for the best camera for your child, keep these suggestions in mind to help. Last but not least, be sure to check out this GoPro HD HERO 960 review.
