During the class, we had a recap on the past lessons such as the different file formats and color spaces. We went back on how png and gif files can support animation and transparent backgrounds and jpg can not. PNG has a bigger color capacity than a GIF. PNGs were uncommon during the early days because the old browsers did not support transparent backgrounds, hence only becoming known with the development of technology. JPG/JPEGs on the other hand are lossy compressions because they are supposed to be portable files.
I learned 2 new things which are about file sizes and another cool photo editing technique. From the past lessons on color spaces (sRGB, AdobeRGB, CMYK), we discussed the differences between 8, 16 and 32-bit images. These are the number of bits per channel. Saving a photo as a JPEG creates and 8-bit image. 8-bit images alone roughly has a range of 16.8 million colors. Imagine how much more 16 and 32-bit images would have. Having a wide color range means more realistic photos. Bigger bits, however, is going to make other filters/features in the photoshop unavailable for use.
Finally, the best part I learned that day is the infamous masking trick. This process involved layering the photo with a mask and using stamps to reveal the photo underneath or create various tones and cool effects. I had such a blast and went wild with this technique. Here are some of the photos I edited --- not much professional, but hey, I'm still a beginner:
