We love to show off our work, but the pictures are dark and/or fuzzy. Here are some quick suggestions for improving your shots:
1. Invest in a digital camera.
I was always picture challenged. Getting a good picture of a window treatment was a gamble that I often lost. An inexpensive digital for your workroom/design studios is a deductible business expense. The cameras have come down in price over the years and come with enough mp and zoom for what you need in taking pictures in a room and posting on the web.
2. Fuzzy pictures.
Prop the camera on the top of the ladder. Or on another piece of furniture in the room. Invest in an inexpensive tripod. They have table-top models that are small and portable.

Learn to press the button smoothly. Sometimes we jerk the camera when pushing the button.
3. Dark pictures. Overcoming silhouettes.
I believe all cameras come with a flash feature. Make sure it is one you can control and is not completely automatic. When taking a picture of a window, the camera picks up the light coming thru the window and adjusts the aperature to that amount of light. In doing so, the lense does not stay open long enough to lighten the details of the treatments inside the room. It is very simple to override this.
First, force the flash. Set your camera for the flash to go off regardless of the light in the room. In smaller room settings, this will be satisfactory.

If that does not work, it is because the flash is only effective up to a certain number of feet. In larger rooms, it is not enough to lighten a second story window or a wide angled treatment. Therefore, you need to fool the camera into thinking there is not a lot of light coming thru the window.
Point the camera to a dark corner of the room.
Press the button 1/2 way. You can hear it whirr as it reads the light and sets its parameters.
Point the camera at the window, without releasing the button, and take the picture.
If you pointed to too dark a corner, your picture will be whited out and heavily over-exposed. Try again, pointing towards a less-dark corner.

If you pointed to a corner that was not dark enough, you will still have some silhouette issues. Point to a corner that is a little darker.
The beauty of digitals is that you can see the results immediately and take another picture, making educated adjustments.
4. Avoid the zoom if possible.
I have found that using the zoom will bring something in the distance up much closer, but it also impacts the image quality. When taking pictures in a room, avoid using the zoom. Simply move in closer to get the details.

And definitely focus on the details.

5. You can't take too many pictures.
Especially with a digital. Today's photo software makes it very simple to sort through the pictures on your computer or the camera, delete the bad ones and select the good ones. But, be sure to discipline yourself to edit the pictures within a day or two. Don't let them stockpile into a job that is too overwhelming.
