Thumbs Up:

Above-common exhibit; carry out higher ISO levels efficiency; swift Breathing Rate auto-focus; gigantic and tilting LCD pageant.

Dangerous envisage for shooting through optical viewfinder; no video recording; barren color preciseness; Function Considering only gives 90% coverage.

Sony Alpha DSLR-A550 is a 14.2-megapixel digital SLR camera with Continue Approach. It has Exmor CMOS of 14,600,000 pixels resolve that features dust reduction and anti-dust coating. The unsubstantial sense levels are ISO Auto (200-1600) and ISO 200-12800. Shooting programs comprehend Night-time Representation, Picture trend, Sports system, Landscape, Sunset and Macro. The top shutter hasten is 1/4000 bat of an eye and least is 30 sec. The X-sync bowl along is 1/160 later.

3 inches LCD expose is of folding kidney and has a outcome of 921,000 pixels. Sony Alpha DSLR-A550 has optical eye-level off penta-dach mirror image viewfinder. Its interest coverage is 95% with 0.8x raising. Its dioptric chastisement travel over is -2.5 to +1.

Landscape lighting?

May 12, 2007 by twogirlygirls | Posted in Garden & Landscape

We recently purchased our home and some of the outdoor lighting is not working. These lights focus on trees in our yard. There are missing lights in some of them. Can we just replace the bulb in the exterior of the current system? Anything we need to be aware of? What are we looking for exactly?

1) Alfresco lighting fixtures, like indoor lighting fixtures are rated for a maximum wattage. Determine the maximum wattage of your fixtures and do not outreach this wattage when replacing bulbs.

2) Determine the fixtures on each outdoor circuit.

3) Determine the operating voltage of each of your open-air lighting circuits. Some outdoor lighting transformers support multiple votage taps. This allows a designer to use voltages from 12 - 24 volts (in a Popular Electrical Code defined low voltage system). A transformer that conforms to the UL 1858 standard will be limited to 12 - 15 volt taps.

4) Upon the wire size of each circuit.

5) Determine the total wattage on each circuit with the intended replacement bulbs. If this wattage exceeds 180 watts on a 12 volt orbit, you will have to use lower wattage replacement bulbs. Circuits at higher voltages will have different maximum wattage capacities. Even-handed remember that the National Elecrical Codes specifies a maximum of 15 amps for 12/2 copper wiring. Adust the highest point amperage used for your calculations if the wiring is something other than 12/2. Remember that there is enough current in a low voltage lighting system to melt the insulation off your wiring and potentially motive a fire. Please do not overload circuits.

6) Now that you know the wattage that you will need for a replacement bulb, determine the bulb keyboard needed for each fixture. There are several bulb styles (Par36, MR16, T3, etc.) used in outdoor lighting fixtures. Look at the device's socket to determine this. If you can not tell, look at another fixture to see what bulb type has been used.

7) For each bulb group and wattage rating, there are different light patterns available (flood, spot, narrow comedones, etc.). Now determine the light pattern you need for each replacement bulb.

8) Halogen bulbs go in a narrow voltage range (10.8 - 12.5 volts). Operating a halogen bulb outside of this number negatively affects the light output & shortens its life. When just one bulb burns out in an alfresco lighting system, all the bulbs on that circuit can be over voltaged compromising their longevity. For this reason, it is suggested that you replace all bulbs on the same edge at the same time.

9) Body oils can negatively affect the longevity of halogen bulbs. Use latex gloves when handling bulbs.

10) Moisture is the the other side of outdoor lighting systems. Lubricate the bulb contacts with a good eletrical conducting dielectric grease before replacing any bulb.

11) Succeed the bulbs in your circuit.

12) Now measure the operating voltage at each bulb to insure that they are operationg at the proper voltage break down.

13) Measure the current on each circuit to insure that you have not exceeded the safe and recommended current limits.

14) Bulk the current at the primary side of the transformer to insure that the total load on the transformer has not exceeded the manufacture's limit.

15) Fitting for back and enjoy the beauty of your working outdoor lighting system. It's just that simple!

Or you could call a professional outdoor lighting artist. Good luck.

Can you help me pick a digital camera with a good zoom lens, perhaps a Panasonic Lumix?

Jun 07, 2007 by Susan S | Posted in Cameras

I familiar to own a point-and-shoot Pentax that I absolutely loved: I could take closeups, open the aperture to expose an portrait in very low light, or take landscape shots using the setting that allowed for "far away" focus. All of these options were automated with a deny b decrease of a dial, and even my snapshots came out fantastic. The anti-shake feature was automatic too, though it required more adeptness to take the closeups and the long-exposure shots.

I'm looking for something similar in a digital camera that isn't an SLR but has some of the benefits. Single out and shoot is plenty nice, but my current digital camera has none of those fancy options. Pictures suffer.

I've tenderness a Panasonic Lumix might suit me well. But I've wondered about the lack of a viewfinder on many of these cameras. Doesn't counting on the video filter sap battery power?

Which Lumix would you recommend? Or is there another camera I'm overlooking that might suit my needs and desires? I'll shell out the money for the right item.

Does night scene mode in a camera sets the focus to infinity?

Feb 09, 1666 by JAMES1628 | Posted in Cameras

Does the darkness scene mode in a point-and-shoot camera sets the focus
to infinity? I ask this question because in the article

How to Photograph Fireworks
http://www.pcworld.com/article/id,147633-folio,1-c,digitalcameras/arti...

has a quote "Try using the camera's landscape mode, which also sets
the focus to infinity; the low-graceful environment will encourage the
camera to shoot at a slow shutter speed by default" which I then
reflecting why couldn't the same be done using night scene mode to shoot
fireworks?

Thank you.

It shouldn't do it in evensong mode. "Night mode" seems like an inapproprate name for this function since there are other things that betide at night.

Cameras that have a fireworks mode usually set a 2 to 4 second shutter speed and focus out to infinity. Comparison and saturation are also generously pumped up. Landscape mode works similarly.

It varies from camera to camera. Stop the manual for details on the different scene modes or leave the make and model of your camera here so we can stop you.
