Reply Constance Reber 4 years ago Hi J,

I did enjoy this lesson and spent a lot of time on it, as this is new information for me. I will split my lesson nhận xét sessions into smaller chunks for now though since, lượt thích an old tệp tin cabinet, too much new front load causes random files khổng lồ fall out the back!

I did have significant difficulty following without frequent rewinds as the control panels are small và blurry, especially following along with a split screen (I use windows và have a large desktop monitor).

I would vày much better with a separate window on your screen that shows the editing selections as (or more) prominent than the sản phẩm results. I have the latest versions of Adobe & a strong machine, but my control options vary from yours at times, which is another reason why clear directions are imperative for those of us who are unfamiliar with 3d controls on PS. Sidebar: my tools are set to default & yet my selection marque only offers a 2 chiều vertical or horizontal line without any scrolling rectangles (used to lớn select render area). So, I just used the lasso (which looks different from yours too).

In this lesson, I really liked that there is not any background noise & that your voice is easy lớn understand.

I am a subscriber now!
