now u really got me excited !!! haha

anyway, handheld twilight or anti motion blur does what? lower the shutter speed and pump ISO not too high ?? i try google but see niothing on this..

Both HHT and AMB use frame stacking algorithms on 6 images taken rapidly by the camera to subtract away random noise artifacts caused by high ISO as well as increase the overall resolution in the final image. Before Sony incorporated this into the WX1/TX1/TX7/HX5 cameras, this could only be carried out during post-processing with software like PhotoAcute. you can read more about frame stacking technology from PhotoAcute's website.

For HHT, the camera will try to use the lowest ISO possible to shoot in low light conditions.
For AMB, the camera would try to set the shutter speed high enough to freeze motion by adjusting the ISO. If AMB is used in bright conditions like sunny outdoors, the lowest ISO could be selected by the camera with the added advantage that motion could be freezed sufficiently that a decent picture could be taken even if you jerked the camera when pressing the exposure button. No camera, DSLR or P&S, I know of could take a picture while the camera is being shaken... try it at one of the Sony showrooms for yourself and be awed.

what is the difference between the Sports mode (under Scene mode), and the AMB mode ? both freezes the action through different means. I believe the Sports mode uses a fast shutter speed to freeze action. When should you use one mode vs the other ?

The Sport mode is quite strange when I try it out at night in my room.... It seems to apply a ND filter across the scene and set the ISO to 800 and shutter speed to 1/125s regardless of the light conditions. The result was under exposure in almost all the test shots. I would probably need to check this out tomorrow in bright outdoor conditions to see if it behaves similarly.

Actually, another Scene Mode option is more relevant and that is High Sensitivity in which the ISO is automatically set to a higher value so that a high enough shutter speed could be used by the camera to take a shot in dimmer environment.

However, in both these Scene modes, the camera only take 1 shot and that's that. In AMB, the camera takes 6 shots very rapidly and stacks them to reduce noise and increase resolution. In this way, the resulting final image is much better as far as noise and details are concerned.

Therefore, AMB is always my preferred choise. The only disadvantage of AMD and HHT is that you can't take several shots in rapid fire succession as it takes several seconds to post-processed each shot in-camera. So maybe the Scene modes are for people who need to take shots in a rapid fire manner and HHT and AMB are for those people who can afford the time to take one shot, wait for it to post-process before taking another shot and so on.

Sports mode is continuous focusing.

thanks. That is interesting. Didn't know that.

According to the user manual, the Advanced Sports Shooting mode...

Allows you to shoot subjects with fast movements such
as sports. While the shutter is pressed halfway, the
movement of the subject is predicted and the focus will​

be adjusted

It however can't be used in low light environments as the lowest exposure setting supported is 1/125s at f/3.5. Any lower, it would just take an underexposed image with the exposure setting fixed at 1/125s, f/3.5. That's why when I tested it out last night in my room, the shots were all under-exposed. Another thing is that the AF Illuminator which helps the camera to focus under low light conditions will not work in the Sports mode.

Comparing the use of the Sports and AMB modes in a brightly lit room in the daytime, I find that the AMB mode might take the same shot with a higher ISO than the Sports mode but with a faster shutter speed and with lower image noise.

If you have the HX5, why don't you try it out for yourself instead of asking others here and in dpreview when some of the people replying (especially in dpreview) don't even have the camera and yet gave replies so authoritatively on features that are so unique to this series of Sony cameras.

ah, another wide reader of forums. Currently I'm overseas without my camera. Will be overseas for another week. In the meantime, I'm getting feedback on the modes so that when I reach home, I can try out the various "hypothesis" and see if they're right. Don't worry, I will definitely be trying it out, so that when the action occurs, I can dial in the right mode the get the pics I want. I'm getting ideas for the various testing to be done, how the camera sets iso values, shutter speeds, aperture in low light, bright light in these 2 modes. Thanks for your feedback. Would have loved to bring my camera along on my trip, but wife wanted to play with it.

I assume the sensor is same with WX1. the main drawback of HX5 is f3.5, but it also provide a longer zoom , HDR and iPan mode. Wonder how would this do better than WX1 in day light condition.

 

[TsQ]

if only they hv a S and A mode .. than perfect !!

 

[Dennis]

You have to be aware that even the M (manual) mode which allow you to adjust shutter and aperture only allow 2 aperture settings when adjusting although the range of shutter speed is available.
This may sound bad to many but is actually acceptable by me in a compact point and shoot camera.

Hey thks for the info.. I mean, coming from canon S series user and a dslr.. its kinda cut the fun even for PNS to hv 2 aperture setting in M mode...

i guess they just want user to use their auto mode... so no point for a full manual features.. well thats a fair assumption

I nearly for this camera until i see not A or S mode.. so holding it back.. but the pana sweep thing is really really cool

 

[Dennis]

The M mode is kind of redundant. This camera is good for it's low light capability and sweep pano. Sony probably thinks that you won't use it but is there just to make the spec.
Having 2 apertures in this P&S actually makes sense due to the deep depth of field for small sensor and the already small aperture on the lens it won't make much of a difference for all the aperture in between.

[torak]

The sweep pano is really cool! How does the camera do panos even though there are so much movement in the background?

guys please keep the equipment forum from degrading into a rojak picture posting forum k?

Pictures posted here should have technical value and not just everyday snapshots.

 

[zoomzoomzoom]

Tried this camera. Really like the form factor but the LCD screen is horrid. The pictures taken cannot be reliably viewed from what are displayed from the LCD screen.:dunno:

I am considering getting this camera. I thought the images posted do tell a story about the capability of the camera. IMHO, they are sure snapshots but they demonstrated its intended point quite nicely...

I guess the pano shots is video footage, a internal programme will adjust the motion blur. I do use my videocam for super pano image but I use photoshop to stwich the footage.

if i'm not wrong...the panorama corrects movement by using face detection technology to identify moving subjects?

Are you just guessing or you read/researched somwhere? if latter, can advise where, i am curious also.

Like the previous poster, I have tried the video grabbed method, but failed miserably! and I have no success in taking pano with 'unstill' people......
