Topic 4: Save images in appropriate format

Saving works a bit differently from most other applications. Instead of working with one main file type—such as .docx in Microsoft Word—Photoshop offers a variety of ways to save your images.There are numerous image file types out there so it can be hard to know which file type best suits your image needs. Some image types such a TIFF are great for printing while others, like JPG or PNG, are best for web graphics. But there are many other options such as TIFF (.tif, .tiff), Bitmap (.bmp), JPEG (.jpg, .jpeg), GIF (.gif), PNG (.png), EPS (.eps), RAW Image Files (.raw, .cr2, .nef, .orf, .sr2, and more).

What are some uses of optimisation techniques.
By opening a new document on Adobe Photoshop you choose what size you want image to be then import image. Then shrink image down to the size you want, then export for web and select an appropriate format type.

What are the sustainability concepts appropriate to the ICT industry, specifically for graphic design or website development.
we can be sustainable by Reducing usage of paper when printing out drafts showing to the clients of the briefs. Also we can recycle paper and printer links by saving environment and money we don't over spend money for getting new link every time we run out link and better way saving money is reusing inks by refilling them.

There are numerous image file types out there so it can be hard to know which file type best suits our images. Depending on what we are going to do with the image,
you have to find what best suits to you. For printing, for editing, for websites.
Every single type of format will result in different properties. It's very important, yes, that's really to save in an appropriate format.

It is possible to optimise an image by using software such as adobe photoshop, picmonkey, PIXLR and canva. Other than using software to optimise images the file format can greatly affect optimisation. The main file types are JPEG, GIF and PNG. Depending on how the image is used will depend on which file format is best.

I agree with Bkoss70, that reducing paper usage and recycling paper and ink is a great way sustainability plan in the IT industry

Image optimisation:
This is extremely important for web development as creating high quality images with small file size is a hard balance. Almost all image editing software allow you to save in multiple file types to help with the decision.
These file types are
SVG - Used for vector graphics, this keeps the image from becoming a raster image (pixel based).
PNG - One of the most commonly used image formats, this keeps the image at a higher quality but not degrading (lose data) each time it is compressed/saved. This file type is often small too.
JPEG - Another commonly used image format, this file type takes size over quality. While these images are much smaller, the image will lose data each time it is compressed loosing its quality over time.
GIF - This file type is used for animations or videos to be easily compressed into a much smaller size. Gifs are very easy to send to people and take up very little room compared to other similar file types.

Choosing the right format is very important for your images.

Bkoss70's post is the best way to get exactly what file type you want for your image. You can also choose between PNG-8 (which supports only 256 colors, but is usually smaller in size) and PNG-24 (which supports more colors, but might be bigger). This can all be seen in real time in the 'Export for web' window.

I agree with your post! well there are always so many different ways to save image in appropriate format such as documents in Microsoft word, Photoshop etc. with different file types.

Good morning/Evening Everyone

With file types, you cannot for the life of you do certain things without it. If you want to save a file from a word document, you will need to save it as .doc and if you want to save an image you either save as a .PNG or .JPG and if its animated .GIF. When you are saving its a major priority that you remember things like these, since a corruption might occur, or the file its self is not able to open.

IT industry has been quite wasteful over the many decades has started making progress with it's sustainability plans.  By being Eco-friendly, recycling more components and reusing when it is possible, the IT section of business can make less of a footprint on the earth.

I guess the most important thing is recognising what type of file to use when saving images to obtain the best results.  I really liked using GIFs because of the animation side of things and the fact that they take up little file space, but now I mainly use PNG when saving images because there is little chance of losing data when the file is compressed.    PNG was created as an improved, non-patented replacement for GIFs, and is the most widely used lossless image compression format.

When trying to figure out what the best format is to save your image as it's always important to take different things into consideration like compression and resolution quality. My personal preference is usually PNG because it retains the image at a higher quality. So I'd recommend to use PNG when you need smaller file sizes with no loss in quality. PNG also supports alpha transparency (soft edges) and was developed to be a Web graphics replacement for GIF.
