Question: Underwater Pictures? Does anyone have any idea as to how this camera does underwater? I'm unable to find any reviews in regards to this subject.
Document: There are several options. Along with everything on the dial, you get underwater, florescent, sepia, black and white, cloudy, day, night, and the list goes on. Changing the ISO is also quite easy. If you aren't knowledgeable about camera options, you'll soon find that when changing the flash strength, you can get better pictures depending on the lighting of the room or outdoors.
I'm sure you've read the reviews of this camera and how it's heralded for great image quality.However, one thing none of the reviews mentioned is that it has a very loud zoom motor. I like the vari-angle LCD for stealth shots, however the very loud zoom motor makes you awfully conspicuous. I'm not exaggerating either.In my opinion, the LCD is too low resolution also. It makes it hard to tell what's in focus and what's out of focus.
The reason that I'm writing about the Electronics Club in this review is because I am unable to leave feedback anywhere else. We spent too much time trying to be nice and give them opportunity to help us. I guess that's why they've totally ignored our e-mails, as we can't give negative feedback any other way.

Many of my pictures are blurry, fuzzy & look out of focus"The same happend to me after paid over 300dls. I got this!!!!. Have you seen the sony camera comercial about the face detection features? that is exactly what happen to me, I shot the pic to my subject,and the subject is blurry.But ooh!!
I use the camera on almost a daily basis. The 10 megapixels produce excellent pictures and prints. Pictures that I have downloaded for training come out perfect. I would reccomend this camera to anyone that wants an easy camera from taking the picture to processing it.
Also, the optical viewfinder is not located exactly where the picture will be taken, it's off to the side. So when taking pictures close up make sure you don't look into the optical viewfinder. This effect is mitigated the farther away the subject is.Just as long as you take these into account before buying, you'll be very happy with this. I like the higher ISO performance, it's very clean when compared to other compact cameras. The flash is powerful also.
These are the kind of photos I have always wanted to be able to produce. My people photos do sometimes have red-eye, but I don't mind editing it out. That's part of the beauty of a digital camera.As for battery life, I've taken hundreds of pictures and lots of videos and I'm still using the batteries that shipped with the camera.
I have had this camera for almost two years and I still love it.It allows me to take great high quality pictures and video. The level of detail in the photos is fantastic. I've posted pictures online from our trips and adventures and people are surprised to find out that it is a point and shoot and not a dslr. The videos come out great too and the sound is fantastic.
If you're looking primarily for an outside-use camera, then this one is very good, but if you take a lot of indoor shots, then you may want to look elsewhere. Not to be too negative, overall I'm pleased with the picture quality of the camera, but here are a few things I found to be both good, and not so good, about the A640. Good-to-great is the high quality outdoor pictures it takes.
This camera is awesome. There are just so many options to play with. I love the fact that you can flip the screen out and take pictures of yourself. You can also take pictures from your computer. Hooking your camera straight to the TV and watching the picture and videos you made is awesome. I'm very statisfied, and the price was outstanding. 10 MP is overkill for me, but it's nice to have it there. The hard black plastic body is very strong and scratch resistant.
Answer: I've used it with a housing and am pleased to tell you that the quality of my photos are amazing. Near macro shots come out crisp, however, any long distance, panoramic attempts will not be satisfactory, not enough light from the on board flash. I've taken some video of clownfish, and find my self going baack to it over and over again.The housing buttons are easy to master and work well. It is quite sturdy and has held up well. I have to admit, I am still surprised how well the small self contained flash works, very little back scatter and deep color saturation.
