A Picture is Worth a Thousand Words
Where to begin...
In order to make the best use of this network, I feel it is important we address everyone's needs, I mean from the novice to the expert. That is why this networks are so cool, because you can share what you know and learn what you don't know, painlessly. It is my hope, we all share our resources and learn from each other. I will post the very basics and I will try to find the best resources for the expert user...and if you are one..Share...Share...Share. We will all learn, and at the end, our students are the winners. I think that is the Goal, the main Goal. Let's all share our ideas and questions and together let's try to answer them to achieve the best result.
I know Digital Images can be a challenge for some, but can also be very easy for others, so with that in mind, I want to make sure we cover the basics about it and maybe you might have a question, or a resource to share, a comment to add, a "best way to do it", a lesson plan you have tried, that you want to share, about those Basics.
We have sometimes questions about files, picture files, how are they call? which one is better? where do I find them? how do I download them? true, valid questions that I hope we can answer here.
What kind of file should you use for your photos?
Overall, TIFF and JPEG are the best file formats for photos:
* TIFFs are ideal for archiving photos. Unlike JPEGs, TIFFs can be edited and resaved without compression loss, meaning quality stays high. If you want to restore old photos or print enlargements of the photos you scan, you'll appreciate the level of detail TIFFs provide. The downside is the size: TIFF files are extremely large and take up a lot of storage space.
* JPEGs are optimal for posting and transferring photos online, since they can be saved as small files. However, the reduction in file size can mean loss of image quality. Another thing to note: JPEGs don't always stack up to formats like GIFs or PNGs when it comes to line drawings or images containing text, so be sure to select a format appropriate to the item you're scanning.
Two other formats you'll see are GIF and PNG:
* PNG files typically offer greater compression and a much wider range of color depths than GIFs. They're good format for line drawings, while JPEGs are typically better for photos. PNG images are not as widely supported as GIFs or JPEGs.
* GIF files offer flexibility: You can reduce the file size of an image without degradation as long as your image contains 256 colors or fewer. Thus the preference for using JPEGs or PNGs for photos, which typically contain a much wider spectrum of colors.
One easy way to make sure your image will always work for any occasion is to save the file as a large TIFF. Then you can easily save as/export to a more appropriate lower-resolution format like JPEG, GIF, or PNG.
