This photoshop lesson was our 4th online lecture of the year. Sadly, I didnt write a post on last weeks lesson...I was there but my brain wasnt...it was still drunk. Anyway, the jist of it was using the web to search for specific information on a person, and how to do it stratigically. (C.A.R.R - Computer Assited Research Reporting.)
So, lecture four, Photoshop. I have used before during my graphics class, but was never taught properly. Theres far too much to learn! Steve showed us some helpful tips for using imagery on the web.
To decrease the size of an image for the web:
- Go to image on the top option bar, select mode and use RGB format for using images on the web.
- It is important to make the image as small as possible to download on the web. So to decrease the size of the file, select image size in the image option, and by making the width smaller, this decreases the amount of pixel dimensions. These need to be as small as possible.
- When saving, use JPEG option for web, click save. An image options box will apear, use a quality of around 4/5 (medium) to compress it for a smaller file.
- This important criteria will save alot of time downloading an image from a website.
Other helpful tools on photopshop to create a high quality image, are:
- The rubber stamp tool. This tool takes colour from other parts of the image and duplicates it. Good to hide bits you dont want in your image.
- Brush tool. This basically paints colour on to your image.
- Magic wand. This can delete whole chunks of the image you dont want. It automatically selects th areas as you click on part of the image.
- Lasso tool. This is the magic wand, but in freehand form.
- Image-> adjustments -> levels. This means you can play around with the darkness of the image.
- Image->adjustments -> curves. Can make the background lighter/darker.
- Colour balance -> play around with levels of RGB colour.
- Hue/saturation -> special effetcs.
- Rotate canvas -> Flip image (just be careful if text is used.)
