Question: How to use Color Accent? The manual isn't very clear... once I set the dial to C for Custom, what do I do to access Color Accent?
Document: My favorite is probably the portrait setting, although the color swap and color accent are really cool too. *It should be noted that this camera burns through batteries like c r a z y. I had it for a month and decided it would be best to buy some rechargeable batteries. So i bought 8 AA batteries and a charger from Radioshack. Now i always have another set charged and ready when i've burned through my current set.
This is my third camera in the A-series. Like its preceders, it takes crisp and clear pictures full of vibrant colors. I absolutely love the Color Accent feature, to turn all but one color black & white, which creates a professional effect of accenting one color. The zoom is also fantastic - I used the 16x to photograph some trees in the distance, and it showed a squirrel on one of the branches that couldn't be seen with the naked eye, without losing any quality.
This wonderful camera is like two cameras in one. You can set it to auto and anyone can use it as a point-and-shoot model capable of some very nice shots. If you happen to like to use manual settings and apply an artistic eye to your shots, it is very good at this as well. I have just started trying to take more artistic shots and this camera is very good for this purpose and has many helpful features.
This camera does some amazing things. I love it. Not as sleek as the other cameras but i don't care. I'll take it with me where I can. I love the color accent features and takes great videos. Sometimes the format isn't compatible and can't upload to youtube but w/ a couple tries I get it. I love this camera. It was dropped a few times. I am determined to replace it w/ the exact same one. I've had it for a year and a half.
don't fight it. you will look around, drive yourself crazy and incessantly read reviews. there's always going to be something bigger and better but for the price, this is a sweet little (not so little i guess) camera. i'm still figuring out all of the functions, but the macro mode, color accent, and stitch assist are very neat and make creative photography a snap!
I have been quite pleased with the A630. It takes really clear pictures with vivid color. The camera is packed with features...more than I've been able to learn in the few months I've had it. I am quite happy with the battery life too. In all, I have no complaints with this camera. Overall, a good buy.January 2013 edits: for the last 2 years, I have had significant problems with the flash.
The camera has a function so that it can take panoramic pictures(it holds part of the previous picture on screen so you can line it up), it takes large video for a camera, you can set it to turn everything into black and white except for one color--and can even make said color(say, blue) turn into, red, or any other color you like. It takes pictures fairly quickly even when using the flash. I'm impressed with the battery life.
I have had this camera for several months (my first digital). Overall, the clarity and color of the shots are great. My big complaint is that most of the time the red eye reduction doesn't work, so I waste countless hours with a photo software taking the red eye out. The troubleshooting portion of the manual states that the subject should be looking directly at the red eye lamp. That's not very easy when taking pictures of children.
It will pull the photos off neatly in to a folder, and even delete them from the camera for you if you want. This is another nice plus. Who needs those silly bloated custom applications that come with these cameras? (And BTW, I am a computer software engineer by trade. )I first tried an A550 (also a nice cam) and exchanged it at the store for this A630, because the 550 doesn't have the manual exposure controls I needed.
This camera has met every need of our family in our picture taking and videos.Pictures are crystal clear. Typical easy off load by cord or memory card of pictures and videos to any computer or photo program. We have 4 computers with a different photo program on each one.You do have to read the manual. This is not an out of the box, point and shoot camera.
Answer: Go to the SCN mode, there you can click left or right on the wheel to see different specialty settings, such as fireworks, underwater, etc. One of your options is color accent. To pick which color to accent, click display. Then focus the little square in the middle of the screen on the color you want and click the left button. You can also change the tolerance by clicking up or down. Also try color swap, it's in SCN and is quite fun.
