It happens when the AF area is aimed at a part of the picture which has no contrast (white wall, sky, etc.) I don't know your camera but some have a special setting for when you are following a moving object. If you have this feature it should keep tracking the part of the picture you focused on originally...

When I look at the subject everything looks ok but after the picture is taken some times it looks out of focus


You need to remember to allow the camera time to focus. Press half way down on the shutter. That causes the camera's focusing system to start. Then, after about a second continue pressing the shutter for the image capture.

Bad pictures on my Digital Camera


A digital camera is a wonderful device - it's just not as good as the human eye yet.
Some things to watch out for:

Spots in the picture - Shiny surfaces reflect your flash back to you.
Picture is dark - Bright Window behind your subject - . Use backlight setting.
Bad focus - Subject is not in the middle of the picture. (Use focus lock if you have it)
Colours don't look right - Sunlight in a building with overhead fluorescents.The camera does not know to use the fluorescent light setting. Set it.
Picture is clear but dark on an overcast day - sport setting is ON or the ISO is too fast. Use auto, 100 or 200.
Flash won't flash and subject comes out dark - light behind subject. Set the flash to 'Always' for this picture.

Do's and Don'ts
Don't drop the camera. USE the hand/neck strap.
Don't store pictures on your memory stick - make copies as soon as you can.
Don't make changes to pictures with your computer while they are on the memory stick. Work with copies on your computer.
Do not allow rain to land on the camera - rain easily runs inside.
If you use rechargable batteries - have two or more sets. Use one set until they are used up, then switch. Charge the low battery only. This maximizes the battery life and provides the longest operating time.
Clean the battery contacts in the camera two or three times a year with 99% pure alcohol and a cotton swab. It does not hurt to clean the ends of rechargeable batteries at the same time. Don't touch batteries on their ends.

Some of my pictures are blurry using a cannon rebel 3. how can i fix this problem?


There are several possible causes for blurry pictures.
1) Camera motion. If everything is blurry, it's most likely because the camera moved while the picture was being taken. Make sure your shutter speed is fast enough if you're handholding the camera (longer lenses require faster shutter speed). Alternatively, put your camera on a stable surface, such as a tripod or a tabletop.
2) Subject motion. If the subject is blurry but the background is sharper, then the subject may have moved while the picture was being taken. Use a faster shutter speed. Raise the ISO if needed. There are limits, of course. If you're trying to photograph a fast-moving object in the dark, you probably won't be able to.
3) Improper focus. If the subject is blurry but something else in the picture is sharp, then the camera probably focused on the wrong object. Move the focus selector to the subject you want in focus. Alternatively, center the viewfinder on the subject, press the shutter button halfway to lock focus, then reframe and shoot.
Without any more specific information as to what and how your pictures are blurry, I'm afraid the above is all I can give you.

Nikon D90 Self-Timer does not work when flash is engaged.


The answer to your question can be found at...

All but the very best flashes can not recycle atthat flash rate. For burst mode, you probably want to use focus modeAF-C or AF-A.
Morris

Page 73 in the manual; If the flash fires in L or H mode (pg. 65), only one picture will be taken each time the
shutter-release button is pressed. The shutterrelease may be briefly disabled to protect the flash after it has beenused for several consecutive shots. The flash can be used again after ashort pause.
The flash can take several seconds to recharge andduring that time the shutter is disabled. NR will also reduce thenumber of frames per second that you can take, and of course yourshutter speed has to be fast enough to allow for 4.5 fps.
In AF-S the shutter won’t fire unless the camera has achieved an in-focus state and the focus is locked.
In AF-C the camera continually focuses, but that isnot the same thing as being in focus. As you move the camera or yoursubject moves, the in focus state will come and go, but the camera willattempt to continuously re-focus. BUT, the shutter will fire even ifwhen the AF system has lost the in-focus state and the picture is outof focus.
In the D90 manual it indicates that the AF-A modewill only fire when the green in-focus light is on, just like in AF-S.The problem is that you probably won’t get 4.5 fps unless both thecamera and the subject are stationary and no time is lost between shotswhile the camera re-focuses.

Pictures are blur


Hi,

Your pictures are blurry because the camera did not focus properly on the subject.

First, turn on the camera in any picture taking mode (or video mode), then look at the screen or viewfinder. There should be four white corners in the center of the camera display. This is your targeting area.
---------------------------------------------------------------------------------------
1. Aim the camera at your subject so this center area is directly on it.

2. Press the shutter button lightly, not all the way down. Wait for a second or two WITHOUT RELEASING YOUR FINGER. If the white corners turn green, keep the finger on the button and press it all the way.

(Once the screen flashes black, a picture is taken and you can release the finger).
----------------------------------------------------------------------------------------
If the targeting area turns red and blinks, then the camera has not focused. You can to try to focus again by following step 1 and 2. If a picture is taken when the targeting area is red, then the picture will be blurry.

If there is no targeting area, then you can still focus by aiming the camera at your subject. Now follow step 2. A green box will appear on the subject, then a sharp picture can be taken.
-----------------------------------------------------------------------------------------
The red arrow that flashes means that the pictures or videos are being written onto the memory card.

Also, try to be steady when taking pictures, because slight hand movement can cause blurry images too.

Page 25 in the DMC-FZ7's english manual will also explain how to focus.

Bad focus when tacking pictures


I had the same problem and disabled the hand grip and full time autofocus. Works perfect now. I must have been doing something wrong with the hand grip in the act of shooting. In fact I sent mine back to the factory and it still wouldn't auto focus. It was my problem. I feel like a slice of cheese for sending it back.

The subject is very blury or out of the picture


You are expecting too much for any auto mode. When shooting under low light conditions, the camera may take longer to achieve focus lock. If the subject is moving too, it will take even longer to lock focus. Try using manual focus for the conditions you described.

Cannot focus on a particular subject


If the camera is having a difficult time auto-focusing, you can try the FOCUS LOCK feature. This feature allows you to focus on another subject roughly the same distance from you and then move the camera back to the intended subject and take the picture without losing focus. First, turn the camera on and locate the Autofocus Target Mark in the center of the LCD. The AF Target Mark resembles an open and close bracket [ ]. Position this AF Target Mark on a subject roughly the same distance away as the subject the camera is having trouble focusing on. Press the shutter button halfway enabling the lens to focus. While holding the shutter button halfway down, aim the camera at the original subject and press the shutter button all the way down.
