If you are looking for ways to make some extra cash in these hard financial times, then this could be the solution for you. If you own a digital camera system and can edit images on your computer (using software like Adobe Photoshop or Apple Aperture), you may have all the skills you need to make a good second income. Do you have a passion for taking photos and sharing them with others? Then you might be able to make a good second income with digital photography. And, if you are interested, you may even be able to make a new career with your photography skills. Many of the top pro photographers began their careers taking photos for friends and family. They had a real passion for the creative potential of photography, and enjoyed taking photos whenever the opportunity became available. If that sounds like you, then you too may be able to start a new career, or at least make a good second income.
Some of the technologies and features can be confusing, and a question most beginners ask is what file format to use. Less expensive compact cameras do not have too many options regarding file formats, other than JPEG and the ability to take lower resolution images. Cameras today are typically ranging in the area of 9-14 megapixels. By allowing you to use say a 3 megapixel option, you can take many more images, but they cannot be enlarged nearly as much as taking an image at 12 megapixels. In the OLD days, just a few years ago, 3 megapixels was considered high resolution for most digital cameras. The Nikon Coolpix 990 was state of the art, advertising you could create a beautiful 8x10 print from just 3 megapixels! Wow, how times change.
The higher end compact cameras and virtually all DSLR ( Digital Single Lens Reflex) cameras, will allow you to select either RAW or JPEG. Note, when shooting in the RAW format, the camera will always use the maximum resolution of the sensor. Although you can get very good quality images shooting at high res. JPEG option, you will lose many of the editing options when processing these images on the computer. It is always advisable to shoot in RAW format, to give you the maximum flexibility when editing your images on the computer.
There are many options for editing your RAW images, on both the PC and Mac computer systems. In most cases, the camera maker will supply some software for your computer, and there are numerous software companies producing software for editing RAW images. Two of the most common include Adobe Photoshop Lightroom and Aperture from Apple.
If you go to the blog mentioned at the bottom of this article, you will see some sample images taken from an editing session using Aperture. You will notice on the left side of the first image, many of the editing options available when editing a RAW file. You can more easily restore detail in both highlights and shadows, because the RAW file retains every piece of information that was captured at the time of taking the image. With JPEG, you lose image data, because JPEG files are compressed, and hence, some data is lost when the file is created. This data can never be recovered. It is gone for good.
In the second image in the blog, you will see a drop down menu in the Adjustments pane, and the Sepia Tone option is about to be selected. The third image shows the resulting Sepia Tone image. Now, while this can be done with a JPEG file, the beauty of the RAW format is that the original file is never lost. The software just makes these adjusted images to Proxies of the RAW file, so you can always go back to the original RAW file anytime.
Another advantage of shooting RAW files, is that you will always have the maximum amount of data available for enlarging your images and making great quality prints. Even if you need to print an 8x10 photo from just a small area of the file, you will usually have enough detail to do so. Remember, you can always create smaller files from your large RAW files, but you can not create large files from a small JPEG image, and expect to get a good looking print.
If you need to email your files, the software will also allow you to Batch Process a whole folder of images, creating a small JPEG file from each RAW file automatically, saving you a lot of time and hassle. Then, for anyone that needs a larger version of the emailed file, it will be an easy task for you to provide such an image.
These days, the price of memory cards has come down so much, that cost is no longer an issue when buying cards. You should always take your photos at the highest resolution your camera will allow. Memory cards of 2gig and 4gig are now so cheap, you can purchase several and have always have a spare with you. So, happy shooting and have fun taking photos.
