On the picture of the oat field it would benefit from better composition. On landscape photos pay attention to where the horizon is at. Often times it can help by putting your horizon at one of the "rule of thirds" positions in the photo.

Continue to study and learn about composition as well has the different features and settings on your camera. Keep experimenting and learning. Get creative in your subject matter and approach. Look for contrasts, textures, leading lines, etc. Make sure your photos have a central point of interest that the eye is led to. All of these are general tips. Above all keep shooting and enjoying the wonderful world of digital photography.

Pets and flowers make good subjects, both for beginners and more advanced shooters as well. So go ahead and practice on your beautiful dogs. One portrait tip for both people or animal shots is do not shoot down on them, Get on your dog’s level. Do not cut off ears tips or paws in a body shot. Learn to see good lighting, and utilize it in your photography. Take a class if possible, or join a local club or group for mentoring and feedback. Visit the library for books on the basics. Learn how exposure is formed by using ISO, shutter speed and aperture. Read and understand your camera manual to get the most from your gear. Look at good images in books and magazines, pay attention to the lighting and composition. Observe with a keen eye. When shooting, think about the light and what you are trying to show your viewer. Pay attention to your surroundings and backgrounds, and shoot to simplify and direct attention to your subject. Here are a couple of links for beginners:

Have fun with your new camera. (BTW, take care of it, always wear the strap so you won’t drop it. I hope you appreciate that not many 15 year olds have a Leica!) Continue to learn and practice. I will look forward to seeing you progress. Best wishes and happy shooting!

Great that you are learning and getting used to the camera but please don’t fall into the same trap that it seems virtually every teen does and just go around snapping everything you see.

Think about what you are taking.
If they are just for your own pleasure then do what you want but as soon as you put them in public and ask for opinions then make them good photographs.

Look at and study shots which are done by successful photographers in the fields you are interested in.
Check out http://www.photo.net – go to the galleries

^My photography

u need a shop front, and 1-2 large format printers, and the photo processor either from Kodak or Fuji, for Fuji, its around $25000-$30000SGD for the machine itself. the price is not accurate because i got this price from my partner not too long ago.

if you want to be the best, provide the best service with the best equipment, fastest delivery and superb quality. and never use 3rd party papers for your printers please…

hope that helps.
