Quick photo correction in Photoshop | The use of the color space "LAB"

Quick photo correction in Photoshop | The use of the color space "LAB" Thanks for subscribing to the channel https://goo.gl/DWeFvM Good day! On the connection Nakroshaev Oleg and the site Photoshopsunduchok. In this lesson we will work with this photo. It is made in the mountains of Dagestan and has a completely faded, non-contrasting appearance, there are no various colors, that is, this picture casts discouragement on us. Let's process it in Photoshop. I will do it in the color space "Lab". Why in Lab? "Lab" gives us great advantages, because there we have divided the brightness and color or chromaticity. Let's translate our picture from "RGB" to "Lab." "Image" - "Mode", select "Lab". With the picture nothing happened, the only thing we have next to the name of the photo, on the tab appeared the name "Lab / 8" - this means that the picture is in the color space "Lab". Open the "Channels" palette. We have completely different channels here than in "RGB" - we have here the channel "Brightness", "a" and "in". The channel "Brightness" is, just, we have the brightness component of our image and it is completely separate from the chromatic or color, unlike the color space "RGB" and 2 channels - "a" and "c", which are responsible for the color . We will use this advantage. Let's make the brightness channel active and, to see the picture in color, I'll turn on the glaze at the "Lab" channel. We have the "Brightness" channel active, but we see the whole color picture with you and now, so that we do not do it, we will have an impact only on the channel "Brightness". Let's apply the "Shadow / Light" correction to the "Brightness" channel. But before doing this, go to the Layers palette and create a duplicate of the "Ctrl-J" layer. Let's go back to the channels, make the brightness channel active and enable the visibility of the entire picture. Go to "Image", "Correction" and choose "Shadows / Light". See how beautifully our picture has changed. "Shadows" I will slightly increase, instead of the standard 35%, I will put, somewhere around 50% and in "Light" the effect also slightly increase, to obscure the sky a little so that the volume appears there. That's the way. I press the "OK" button. Now, we will apply such a very interesting technique. We will superimpose channel "a" on channel "a", but in a certain mode of overlap. Accordingly, we will do the same thing in channel "c". This we will do with you using the command "External Channel". We make channel "a" active, go to "Image", "External channel". The target channel for us is "a", it is active in our country, that is, all the impact goes to channel "a". Among the channel list, again, select channel "a", that is, channel "a" will be superimposed on channel "a", the mode of overlay is selected not "Normal", but choose "Overlap". Look at how our picture has already begun to play. I will remove the checkmark "View". Here such was, here such picture we with you have received. We have added a red-green color to our photo. Why, exactly, this color? The fact is that the channel "a" answers, namely, for the red-green component of the photograph. Click "OK". Let's switch to channel "c". The channel "в" is active, that is, now all the impact will pass to channel "в". Again, "Image", "External Channel", among the channels choose "in", the overlay mode "Overlap". Let's see what the overlap gave us. That's how we had it, that's the way it was. Look at the sky, it has become more blue and a yellow color appeared on the picture. Why did it happen? The fact is that channel "B" is responsible for the blue-yellow component of the photograph, therefore, we have added blue and yellow colors. Click "OK". Let's go to the Layers palette and see - here we have the original snapshot - see how awful it was, and so that we would get with you literally for 2-3 actions in Photoshop. We only need to translate the photo back into the RGB color space. "Images", "Mode", "RGB" - Photoshop offers us or perform a mix or not. I'll choose "Do not do it." And here we have the final result, already in the color space "RGB". That's how we had it, that's how it turned out. Look, what a wonderful result we have received. The color space "Lab" gives us great advantages in correcting our photo. If you are interested in the topic of the color space "Lab", write in the comments that you want to know more about this color space. If there are enough comments, I will write a few lessons that will help you make a faster correction of the picture than in the RGB color space. Thank you for attention!
