Per Channel Adjustments in Photoshop

Every panel has a pop up menu so you have in this case the option of resetting if you just want to start again there is an auto button here and I must be honest and save my opinion of auto has changed quite dramatically in the last couple of years because before I used to just be very blunt to say don't use anything with the word auto in it because who the heck is auto and what does he know how is he going to adjust my photo back for me but they've made some significant changes to the way that the auto function works in the last couple of years so I would now say it's worth a try and click on it to see if you like it or not it's I wouldn't rely on it extensively because for example in this case I clicked auto and it took the highlight triangle moved a little further than I would because to me I'm already seeing some pretty nice highlights so but at worst you can always say well that's what it wanted but I'm still pushing this back because again that's the bands of unjust malaria is not...

hing is ever a well I don't have any choice now of you know I have to live with what it is okay yes question for somebody online do you do the full level and then each channel second or do you just start with the channels that I would say that again, that's a personal preference, I think most people, if they're going to use channels, they just start there, but even that you might look at and say, well, now they've done that. Let me see if it makes any difference or not. A lot of these the reason I'm showing various methods is everyone has different methods, they kind of like to say, this one works better for me. I'm more happy with the results, we have to always remind ourselves do that a lot of this thing is all about perception because technically values can be a certain number, but a certain point it's, like, do I like this or not? And of course, part of the challenge here is were making judgments of whether we like they're not based on a monitor and if I'm no, I'm going to put this on another monitor like my portfolio online. I'm ok if I'm going to print this that's a whole different thing because what you see on the screen is not I'm going to get on your printer most times unless you have a very high end model that's been very count, carefully calibrated and everything else actually, I just mentioned that for one other. Moment cause I mention this to a few people in the past and people have seemed to find it valuable I worked on a laptop almost exclusively so I tried putting on those fancy little calibration things on here didn't work so much because the technology of thes lcd monitors on a laptop don't really aren't the same as it is a technical monitor but one thing it did happen though is when I was going through this calibration process one of things that said is now change the physical brightness of your monitor so these two gray boxes look the same and I was going lower lower lower lower I could not believe how much I had to turn down the brightness to make the match and I suddenly had this one of those lightbulb moments where I realize all those times I'd be were complaining saying my printer was too dark the real problem was one monitor was too bright so that's like the simplest way without going into heavy duty calibration and I'll tell you right up front you'll hate it for the first three weeks because every time you look at your mind that's some dark and what I do is if I'm doing something like browsing around the internet I'll put my brightness back up again because I hate looking at web pages that air so dark but once I started doing that when I made prince they suddenly looked so much closer because we're looking at this thing that's, backlit, that's projecting light in our face, or comparing that with ink on paper it's never going to be the same, and anyone who says, well, I want them to match, you have to make your life better by setting yourself up, so we'll be a closer match. One of ways to do that is to change the monitor brightness and then use some of these methods that arm or based on what the history, graham says. Not just what you think, and you can also do a quick test and say, I'm going to do a test print and see if I'm closer and things of that nature. Another quick question from alfred myers and then a couple other people also want to know the answer could adjusting the levels on the different color channels, abuse for correcting white balance and order? Does that affect white balance in general? It does affect white balance and one of the the things that I find still a little odd to consider in today's version of photo shop, which, however, whatever number it is now, because now the sec twenty fourteen we don't really know what that is it's like, I don't know fifteen or something who knows is that there's not just a tool and photoshopped called white balance tool it's in cameron's and light room so my answer is very simply, that's one. The reasons I use the camera all filter from within voter shopping is like, just open it and as you'll see, click on white belt. So answer the question. While you can let me say this way, it will affect the white balance. It's hard to make an educated adjustment, is just it will affect it as you're doing it on that per channel basis.
