AGAIN, lazy bum sign in. It is all in adjustment list at the right hand side panel in Photoshop.
I just play around with them, every effect is written below the photos. But the portrait photo (Yup, my beautiful mom with fan.) I actually used multiple tools in adjustment lists, which I can't really recall, since it is last semester's work for photography class (Depth of field). And that time I learned that we should select the layer properly before we use the tool. I made a mistake by forgetting to select the background(as in the photo) instead of using the effect layer before I use burn tool. That is why the effect can't apply on it. (Blur newbie mistake. LOL)
By the way, for your information, burn tool... in my understanding is a tool that darken your image, when you put your photo or paper on top, remember, ON TOP, not right in the fire, you will start to see the photo or paper starts to turn yellowish, and by the time past by, it will turn into brownish.
That is why this tool is called as burn tool.
The other photography assignment from last semester, sunrise. (Great hazy days, this is the 'best' photo I can get in that condition.)
I used the burn tool to make the yellow colour in the bottom more obvious. (Okay it looks weird but... I tried my best. Learning process.)
And yeah, my favourite tool - contrast. The lecturer advice that do not go over 55. It will be too over edited.
That's it. Thanks.
