I learned a lot about operating cameras on digital-photography-school.com. They're a good resource, and they have articles on stuff ranging from theory, gear usage, and post-processing.
In general, make sure that you're exposing properly. I'm a Nikon user, but I'm pretty sure your camera has something the equivalent of an exposure meter inside it's viewfinder. It usually looks like this: <------O------> And has bars around it to show where you're exposed. You'll want to ensure that those bars are lining up to the O in the middle. That's a good start.
One way I've seen people learn is to wade into M mode by jumping into P and A mode. I liked to use A mode when I Started out. this would let me adjust the ISO and the Aperture, but did the shutter for me, so it was one less thing to worry about as I got the hang of changing the different settings. Usually try to keep your ISO between 100 to 400 for most shoots, as this will help reduce noise. I shoot up into the 3200 rarely, but I think I've shot that high only 3 times for a purposed shoot (IE something I was making money off of or intended to show here on dA.)
As for focus, I continue to this day to use autofocus except in rare instances when manual serves better (ie, on my most recent shoot I experimented shooting into the sun for flares, and autofocus would often focus on the flares over my subject.) I think the best way is to build into it slowly, like with any art form.
I hope that's of some help. If you've got any other questions let me know. Always happy to answer. And happy shooting!
semakin besar asa/iso, semakin besar cahaya yg diterima semakin kecil f, semakin sempit depth of field, semakin banyak cahaya yg bisa masuk semakin cepat shutter speed, semakin sedikit cahaya yang bisa masuk. tinggal atur2 ketiga itu aja sih. semoga membantu kk
I remember I was so confused about this too when I first got my DSLR. Try turning your shutter speed down as well as your aperture. Turning up your ISO helps too, but this can sometimes make the picture look more grainy. Balancing these three settings together makes for a good photo.
It's your settings, the camera is not receiving enough light so the result is black. Aperture or focus also controls how much light reaches the sensor so you have to balance it out with your shutter speed, f/stop, or ISO. Here read this ---> [link] . Since your photos are turning out black your shutter speed is to fast (Example: 1/4000 is a real fast shutter speed) you need allot slower shutter speed to allow longer exposure to light (example: 1/30 is a slower shutter speed). But be careful to slow of an shutter speed you can over expose your shot and "blow it out" and it will become completely white, it all depends on situation.

In one basic sentence, each one of those modes has other controls on the camera that control how an image is captured unlike automatic mode where the camera does everything for you.
If you want to use those other modes you need to learn where and how to adjust those other controls that are switched on by using the other camera modes. You can usually download the camera manuals from the manufacturers website. Other than that the question is too general to answer on a forum like this. You need to spend time reading the manual or lots of time playing and working out how the other controls affect how the image is captured in those modes.
In all seriousness, read your manual. It explains the uses of each mode, and the details of what the different functions do. I found that to be massively helpful. It will help you with learning the controls, what the shooting modes do, and some basic photography terminology. I have the previous model, the 1000D, and literally everything you need to know about using that camera properly is in the booklet provided when you bought the camera.
As for those modes, P is essentially for portraits. M is fully manual shooting, and the other three are variations of different styles/levels of optimisation.
Get a book dedicated to the camera you have, it's what I did when I bought my SLR as before then I had no clue how to use one!!! It's been very useful in explaining all what you can do in each mode and how to get the best pictures.
You might have the settings wrong. Try bringing your ISO up to 400, F-stop as high as it'll go, and shutter speed down to about 1/60. And/or use flash. Make sure you're on M. If you're still getting a blank result, I'd suggest taking it to someone, because even if the picture isn't good (wrong settings or being fuzzy or something) you should at least get something. If you can find a troubleshooting guide for your camera as well, that may help. Without the camera in my hands, I'm not sure what else I can say.
