KEEP PHOTOS IN LEVEL WITH BUBBLE LEVEL

Some times is difficult to keep your photos in level and this isn't your fault at all.You can try to expand your tripod legs but still you notice that your photos are 1 ore 2 degree of center.
What can you do in these cases?
There are two solution in these case:
1.You can buy a good tripod with a build-in bubble level-you can find different types from different brands.The best one that I could find online is the type shown in the photo.It is called the Slik PRO 700 DX.It is highly ranked for:Photo Enthusiast, Amateurs, SLR Cameras and Backpacking but the problem is that it cost 100$-140$.If you can't afford one or if you already have a tripod and you are pleased with that one even if it does't have a buil-in level,you have the second solution:
2.Cube Hot Shoe 3-Axis Bubble Level-It does not cost to much so I think everyone can buy it.It costs somewhere between 11$.It is useful and fits in any hot shoe of dSLR cameras or in any advanced digital camera like the canon G9 or canon G10, every photographer can shoot photos more accurately and check the angles of their camera seconds before taking that shot whether you are on uneven ground or just drunk.It can be used in horizontal shoot but also it can keep vertical level in the that exact position, making your photos straight and true.Your camera will look a little strange with the bubble level but it is not uncomfortable,as it is very light near 20 gram and its dimensions are: 2.5 x 2.5 x 2.5 cm.

PS:The only thing you have to keep in mind when using bubble level , with the tripod or Cube Hot Shoe 3-Axis Bubble Level is to center the bubble between the inside line pair,as it indicates level.When it touches one of the outer lines, it means the level is pitched at a 2-percent grade (about ¼ inch per foot of run), the slope required for waste lines, sidewalks, and rain gutters to drain properly.
