Flash pictures too blue - optio 750z - help?

I've had the optio 750z a short while, and like it overall. However, one problem has been taking indoor shots. With a flash, they are invariably too blue and washed out. really unattractive colors. people look terrible, like under bright flourescent lights. Without a flash, the colors are about right, if ever so slightly warm. But that's due most likely to the long exposure necessary, and picking up the tungsten lights. Outside in natural light, the pictures look good. Since it appears to be mostly a flash issue, I'm assuming it's not white balance? Any ideas?

Since your EXIF shows WB as manual maybe the problem has been pinpointed. I just ran a series of tests consisting of 3 groups 6 shots each. The mode switch was at "P" and all other settings, other than WB, were at default or auto. Group 1 - auto flash Group 2 - forced flash in sunlight (incase the camera checked an EV threshold) Group 3 - flash off In each group I varied the WB starting at auto and ending at manual. The EXIF for group 1 and 2 all showed auto WB, group 3 showed auto WB as auto and all others as manual. So, any time my camera fires the flash the WB goes to auto.

It does look a little less warm than the Fuji image. Why is there so much apparent haze on the o750 image, it almost looks like your lens is smeary or something. Its particularly noticable on the flowers. Have you checked the exif data to verify if the WB is forced to AUTO. I would take a flash photo with WB set to some other setting and see what the exif comes out as. I will try this sometime on the o555 to see what it does. At the moment, I have no other ideas except there may be something wrong with it that needs repair.

I have an Optio 750z too. I find for indoor shots, I set up one of the User settings. In User 1 for indoor shots I increase colour, use spot metering, reduce flash comp, increase EV to +.3, set WB based on incandescant and a few other options. You will need to set it up for your needs . User 2 is set up for low res shots and battery saving when I go away camping and want postcard type shots. User 3 is set up sports shots (my kids)

Try playing with the exposure compensation lever. Turn it down a few notches when you use flash. I do that all the time to prevent over exposure Or you can set the flash compensation in the setup.

Very grainy pictures indoors at night

If you can adjust the ISO sensitivity to a lower number then the graininess will be reduced.

However, by reducing the ISO, you will need a slower shutter speed and a larger aperture. A tripod, table or other support may be necessary.

The "noise reduction" setting on the camera can also be adjusted a step up.

Taking pictures at full resolution and fine compression will also help.
----------------------------------------------------------------------------
Overall, at least try lowering the ISO, and using the flash brighter.

Picture blurry or out of focus.

Make sure your subject is within the camera's range. You should be at least 31 inches away to take a picture without the flash, and 31 inches to 8 feet away to take a picture with the flash. You can take a picture as close as 8 inches in macro mode. When you take macro close- ups, make sure you have adequate lighting (with the flash disabled). Using a tripod will help you capture sharp pictures. Make sure you hold the camera steady after you press the shutter button (until the red light starts to flash), and your subject isn't moving. If you are shaking the camera when you lock the focus, a warning icon appears in the right corner of the LCD. If you want to photograph a moving subject, you can change the shutter speed while the camera is connected to your computer. Try increasing the shutter speed. For more information, see Chapter 6. Make sure your flash is not set to flash off. When you focus on a nearby object, your picture's background may appear blurry. Try changing your focus.

Optio s - flash problem in low light

Read the photo data (EXIF) and confirm what setting the flash was in. It may have been set to off by mistake. For close indoor shots I usually don't depend on the Auto setting, just manually force the flash on to get proper lighting. If you use the Auto setting take into consideration the white balance and the type of indoor lighting you are using.

AWB problem on 555

I noted that situation, but was my fault because i've been using Bulb or tungsten in outdoor pictures...!!! AWB works fine most of the cases except in some indoors where i have to use manual WB. Please be aware that if you have enough indoor light could be a good idea to disable the flash, try and error......

Pentax 750z - Movie Mode - Problem

FedEx just dropped off my 750z a few hours ago(!), so I have only had a short time to play around with it. I did try 1 quick video at 640/30fps, and I did not see anything like what you described (perhaps you could grab a jpeg frame from the vid and post it here so we could see?) My only thought is: What is the speed of the PC that you are playing the vid on? It has been my experince that the MotionJPG encoding that cameras use, while fast for capturing the video can be a dog when it comes to playback. I suggest you either try playing the video on a fast PC (if, in fact, yours is not), or try re-encoding the vid with a more efficient codec. (for that you'll need quicktime pro, or a similar program such as RAD Video Tools which is freeware)

This is normal for the 750z.. a friend of mine has the same problem. If you try to print straight from the camera, everything is too bright. My friend has to manually lower the brighness and raise the contrast on every picture.

Mac drivers for 750z

Oh, there's no problem. I don't have an Optio 750z, but I do have an Optio 30 and it's older. Just tested with an iBook G4 that I just have installed Mac OS X Tiger 10.4.2 in. When the camera is attaced and turned on, iPhoto will open automatically and you have the option of import the images to your computer - you can also mark the "Delete images from the camera". The camera will also appear on the Finder desktop as a removable disc. So, seems to be no need for extra software.
