I need help with taking pictures....

Ok so I just posted but wanted to post a separate post with some pictures I took today. I LOVE taking pictures sooooooo much, my family teases me, lol...My mom says we would have no photos if it weren't for me, lol. I always say ok do this and do that and have everyone posing and talking to each other, I love to get casual, natural pictures. BUT, I am a horrible picture taker, though I don't have an expensive thousand dollar camera I do have a pretty nice one. I have no clue how to work all the extras, I just know how to turn it on and snap a picture. Somebody, anybody, Please Help! LOL...I need to know where to go to get picture taking tips and what nots. I want to learn soooo bad! Are the pictures all the wonderful photographers out there edited alot? Is most of the prettiness of the photo done on the pc? I have no clue but I want to know! What am I doing wrong? Now I like to take fast pics, alot in a row, but it seems the more I take quickly the blurrier they are, why is this? Most of the time the pictures are taken in good lighting, so why is the lighting in the picture always terrible? To bright or to dark? I just don't get it, I am so envious of those who can take a good photo. Like for example Etsy, those selling their goodies take the most beautiful pictures of their items, I hardly see a bad photo of an item on etsy, now I know all selling on Etsy have not taken photography classes, right? So how do they do it? Is it a must to have a super expensive camera? Ok so I am rambling on, lol...Now for some pictures so you can see my dilema for yourself....


Ok first up is a picture of my twin sisters...


Here is a picture of my aunt amy mocking me, lol...They were all teasing me about my photo taking obsession, lol...Now see why is this picture so cloudy looking?

Again here is my auny and brother teasing me, lol...They crack up laughing when I say hey talk to each other so I can get some pictures...But how fun are these in the moment photos?

Here they are being nice, haha...JK...

Here is my Momma and the twins, now see how off the lighting in this one is? Is it just me? Hmmm...

Well that is just a few of the MANY MANY pictures I took today, I think my card had over 400 on it by the end of the day, lol...

Thanks for reading and looking!! Any picture taking tips are much appreciated!
