soufiej, which programs do you think would be easiest to use? I have tried a few of the online editors and the software edit the camera came with. I find the software editor is useless. It doesn't do much in the way of editing anything.
The photo of the star ordiment I used a website editor program called Pixlr. It was decent but I found it didn't have very many settings.
As others have mentioned, much of the issue here is white balance. You'll really want to shoot in RAW to be able to correct white balance issues later with an editor program.
Personally, I use Photoshop Elements 10 for all of my editing. It doesn't play well with Canon's .CR2 RAW file format so I have to use Adobe's converter to get everything into .DNG format before editing but that is very easy to do. Once there, Elements is easy to use. It really isn't that hard at all. 99% of the stuff you'll want to do is very easy. When you load a RAW photo, it'll automatically open in a dialog with a bunch of adjustments for white balance, sharpness, lighting, and color. After that, you click to "open" it in the full editor. From there, you can easily fix red eye (pick the red eye tool, draw a square around the eye, boom, done), delete unwanted objects (click the healing brush, draw over the problem area, boom, done) and so on. It really is very easy to use and can generate fantastic results. If you need a guiding hand to use it, I recommend Scott Kelby's book "Photoshop Elements 10 for Digital Photographers".
NOTE: Elements 10 is not the newest version of the app, it's just what I have. It can probably be purchased dirt cheap or you can use the newest version by subscribing to Adobe's services.
I readily admit to be an old codger when it comes to image processing systems. Simply reading the above post makes my head hurt and my thoughts turn to,
"WTF?!!!" . The idea I have to use a program to move my photos' data to another program is, IMO, absolutely the beginnings of insanity. The , "It's just that simple", and the, "Bingbang, whalla polloosa, I can generate fantastic results", sounds like one of the twenty two minute with commercials home improvement shows which are everywhere I look on my satellite TV's viewing options. Sort of like, why do I have "Amercia's Top 250" package of channels when a full 125 of them are about nothing other than redoing old houses, old cars or old recipes or watching old TV shows I've already seen forty years ago?

I end up watching six channels - when the darned thing works. Several years ago I had a "tech" from D---------k walk out without finishing the install because he couldn't understand the way the thing worked. Fortunately, I sold the system, I talked the jargon, I knew the way the system should operate and after he aligned the new dish up on the roof and ran the wires through my attic, I did get the system up and running. But, still ... ?! Why???!!!
While my advice to the op was to read about the various options she might explore, I fully understand just reading the dozens upon dozens of dozens of search engine blurbs which describe these dozens upon dozens of the various options is like reading some weirdly written mystery novel filled with high tech jargon and serial intrigue which never has a payoff. Sort of like "24' where everything is so unrealistically simple and filled with such leaps of logic as to be comical. Then you make your pick, load it and it's sort of like watching "Resurrection" where you wait and wait and wait and wait and none of it ever makes any sense and you always find yourself asking, "Why did I waste another hour?". When will something actually happen on that show???!!! How do you OK a program without a story? This makes no sense to someone who grew up on "The Dick VanDyke Show" and "My Mother the Car". I begin to think I should be like Barney and only need one bullet.
And, while I fully understand the sincere desire to provide information to the op, such a response can, IMO, be taken as having been written in some foreign language and encouraging me to climb to the top of the nearest mountain and jump off, most especially for an op who asked, "Why are my shots yellow?" So, Tabe, I'm not saying anything about your response, just considering the fact taking a photo is no longer a function of just getting things right in the camera. Even that is impossibly complicated nowdays for many of us who grew up with $10 point and shoots which didn't even allow for a wild hare decision to use 200 ASA film.
I'm just now returning to photography after a long lay off generated primarily by my frustrations with computer software and their absolute necessity for turning out an image I can hold in my hands. And that's all I really want, a photograph I can hold in my hands and not be forced to view on my computer monitor. Years ago I could take that photo and put it in my wallet. Now I have to have even more bing bang zoom software, usually duplicates, just to move it to my smart phone which doesn't share the same operating system as my laptop. WTF?! Personally, I don't even want to share
anything over "social media". Who would care that I saw a robin today? If they do, I'm more concerned about them than I am about most everything else. When I had a telephone with a cord and a rotary dial I never once told anyone I saw a robin today. Why is that big news today? Why does it need to be shared with twenty "friends"? They're just going to delete the thing anyway. What is the point?
And, quite honestly, when I load an image processing program into my computer for a trial run - as I did yesterday - I am somewhere between, "Why did I do this again?", and throwing the whole darned thing into the trash or against a wall. When I read comments such as your's, Tabe, I think, "Yeah, this is simple ... for a six year old who knows nothing but computer stuff", and, "Why is the idea of getting a photo I can see so @%*^**&#!!*& difficult nowdays?"
Personally, I absolutely and from the bottom of my soul detest sitting in front of a computer taking what I consider to be a"good shot", extracting that data from my camera, transferring it invisibly and possibly not so successfully to the computer while hoping against hope the data actually operates as data and shows up as an image and then facing the absolute necessity that I spend another (largely wasted) amount of time first deciding on
which software to download (get the one that doesn't have the virus attached or you'll be spending a lot more time and a lot more frustration) just to try, while learning what seems to be a completely weird and darned near incomprehensible menu system that doesn't do what I want it to do and continues to tell me I must do something to something which I cannot find on my computer before I can "fix" that good shot. If it was a good shot, why must I "fix" it in the first place? That has always been the ridiculousness of "digital" photography to me.
I can think of little as torturous in everyday life as reading about image processing programs. Except, actually trying an image processing program.
Trying to find the basic "help" files as I download a new possibility and wading and wading and wading through all the stuff that doesn't assist me one little diddly bit because I don't know and don't want to know what the hell a "brush" is. And I certainly don't want my good shot ruined because I experimented with a brush. Paying a monthly fee to do this? What is this, some kind of Catholic limbo I've stumbled into which will only allow me to emerge from the other side and into the promised land once I've paid for an entire lifetime of petty sins?! Then there's always, no matter which software I am trying out, Adobe or Java or Windows popping up yet another screen in the middle of the process insisting I download yet another revision, update or security blanket to their program before I can progress and, then, once the download is completed, finding out the image I had been "fixing" has somehow disappeared, never to be found again and certainly never to be "processed" again from the same point. So, after finding the "photo" data once again, I begin again with the entire $%%#@(**& process hoping just this once I can get to the point where I can actually print out a tiny little 4X6 sheet of paper. Something to actually look at and to call my own, not some group of invisible, magical data points in someone else's software which I can only see with the aid of a computer. And, what? I find I have not yet calibrated my monitor and my printer to the "correct" RGB standard. Or I shot in Jpeg because that's what my camera selected for me rather than what I wanted. And everyone on the forum is telling me I need to shoot in RAW because that's what makes me a good photographer.
WTF?!
THAT"s what makes me a good photographer?!
*&^&*^&%$%$#@@#%&*%$$%^#@!!!!!!!!!
But, I can't because some other BS has prevented it from happening and I have no ^%%&^$#@* clue as to what it is or how to get around it.
I really, simply have no real idea how consumer photography reached this point where I can't check all the things I need to check with my camera (four, maybe five tops), aim and take a photo which I can actually call my own and not the work of some geeky genius who wrote the $@!((*& processing program. Between everything the camera now does which actually prohibits and discourages me from getting a correct group of data points (crimeny, it's just 1's and 0's for goodness sake!) , to all the work I must do before
AND after I transfer the data into a computer, I am astounded photography beyond a simple smart phone snapshot kept only on my smartphone is still seen as worth the effort by so many people. And why I suspect a lot of rather pricey DSLR's are going to end up gathering dust on a shelf in a backroom closet.
".DNG"?!
That alone sounds like a band I wouldn't listen to.
(PS: This was posted using a Google Chromebook. No, it's not a "real" computer because all it does is allow me to get on the internet. But it does so in one second from the time I open the cover and it loads websites in about two seconds, at the most, from the time I click on a link. If I had tried this on my Windows based laptop or PC, I would still be waiting for either of them to reach the point where I could even open up a browser.)
