Eos 7d Weatherproof
Canon 7D, Canon EOS 60D or Sony SLT A55, which one is better for shooting movies?

and what is the best editing software? Thank you. and what is the weatherproofing? I read the Sony doesn’t have it. Does it make a difference?

Hey,

Weatherproof body means it’s less likely that anything is going to wrong with your camera when it rains. 7D and 60D are professional bodies, A55 is not.

Canon eOS 60D and 7D have the same sensor, so they have the same image quality, noise performance and video – which is Full HD at 24/25/30fps and HD at 50/60fps. Sony A55 is not that good.

I recommend you to go with 60D or T2i (which is a smaller 60D).

What is the concealment of the USM or approach?

The most common method of sharpness of an image in Photoshop is to use USM or the Unsharp Mask filter. The blur filter mask has its roots in traditional print and darkroom is to increase the contrast on the banks of detail. This contrast enhancement is an increase in perceived sharpness.

USM How do I use?

Before go too far, we will show there is no set of instrument settings for all occasions. Many beginners think that you can use only an amount of USM for all images, but is generally not possible. The amount of sharpness to make a basic picture of the image.

Of course, if you regularly images of the same basic size, for example, for the gallery on the Internet is possible that a number of sharpness of most of the time, because the size of the image! To determine the amount of USM necessary, it is preferable to look how we want to use the image.

Internet

On the Internet, where the image is displayed on the screen, usually resize the image to produce a reasonable size on the computer screen. To view the resolution screen "the image displayed in the image format is not relevant dialog Photoshop (This is only used for printing), only information that is important are the pixel dimensions of the actual image. Now, most monitors display a screen resolution of 96ppi (pixels per inch) and the most common sizes are 1024×768 pixels or higher screen. Therefore, if you want a image to fill half the screen on a 1024×768 screen width should be 612 pixels. This would produce an image a little over six inches width of the screen.

So, change the size of our image (and keep a copy!) To 612 pixels wide. Now, we apply USM. Because this image is only intended to be viewed on a computer screen just use your eyes to determine the amount of sharpening. Set the preview USM verified visually. If you get a halo around the edges of the back, you've gone too far!

It's easy As you can see the results immediately, just use trial. If your screen size is bigger than 1024×768 adjust the figures their own screen and you have absolutely no control over the screens of others. Just stop thinking about the size that you want to see image on the screen and use pixel size to get (or used to calculate 96ppi inch screen). All this is done for you by using the PS dialog Image size does not need mathematics.

If you present your photos online, libraries, or for use in products Printed should follow the guidelines established by the site you send pictures. Most commercial sites have a very detailed help to guide you.

After making a few simple tests you need to learn everything you need to know about USM photos to the Internet without worrying so much or little I use. Incidentally, it is also their preferences for visual images on the Internet!
