Sony dsc t77 software

You can read details of this test here. Low light. To get brighter images at any of the darker light levels, the camera required almost the highest boost of sensitivity, at 1, Thus, you'll need the flash for any night shots with the DSC-T How bright is this?

The one foot-candle light level that this test begins at roughly corresponds to the brightness of typical city street-lighting at night.

Cameras performing well at that level should be able to snap good-looking photos of street-lit scenes. NOTE : This low light test is conducted with a stationary subject, and the camera mounted on a sturdy tripod.

Most digital cameras will fail miserably when faced with a moving subject in dim lighting. For example, a child's ballet recital or a holiday pageant in a gymnasium. For such applications, you may have better luck with a digital SLR camera, but even there, you'll likely need to set the focus manually. Coverage and Range Limited flash range, with a tendency to underexpose. Our standard shots required a high intensity boost, and even then produced dark exposures.

Coverage and Exposure. Flash coverage was dim and a bit uneven at wide angle, but such results are pretty average. At full telephoto, the flash couldn't match the camera's 4x optical zoom. In the Indoor test, the Sony DSC-T77's flash underexposed our subject at its default setting quite a bit, and even with the High Intensity boost, produced a dim image. The camera's Slow-Sync flash mode performed much better, producing a bright image at its default intensity level.

Color balance is warm from the background lighting, with a strong yellow cast, but results are usable. ISO Range. At both wide angle and telephoto at ISO , flash shots were already dim at 6 feet, with decreasing intensity from that point on. Manufacturer Specified Flash Test. Such high ISOs will definitely degrade image quality on flash shots at anything other than very close distances. Our standard test method for flash range uses a fixed setting of ISO , to provide a fair basis of comparison between cameras.

We've now also begun shooting two shots using the manufacturer-specified camera settings, at the range the company claims for the camera, to assess the validity of the specific claims. Print Quality Good print quality, good color, sharp 13x19 inch prints, very usable to 16x20 inches for wall display. Color suffers somewhat at higher ISOs.

The Sony DSC-T77 did fairly well in our output quality tests, its images proving quite usable for wall display as large as 16x20 inches, and 13xinch prints were decently sharp. As always, quality degrades at higher ISO settings, but the T77 delivered images that could make soft but very usable 8x10 inch prints.

At ISO 1, and 3,, the color is noticeably flatter and more muted. Color-wise, the Sony T77's printed output looked good, with most colors bright but believable looking. The exception was strong reds, which looked a little hot, but this seems to be a common tendency with digicams these days. Hue seemed pretty accurate, though we did notice the cyan-toward-blue color shift we noted earlier in some of our test images. Testing hundreds of digital cameras, we've found that you can only tell just so much about a camera's image quality by viewing its images on-screen.

Ultimately, there's no substitute for printing a lot of images and examining them closely. For this reason, we now routinely print sample images from the cameras we test on our Canon Pro studio printer, and on the Canon iP here in the office.

The images above were taken from our standardized test shots. Not sure which camera to buy? Let your eyes be the ultimate judge! The Sony Cyber-shot DSC-T77's 4x optical zoom lens covers a range equivalent to a mm zoom on a 35mm camera, slightly more than the 3x you typically find in subcompact cameras like the T At full wide-angle, detail is pretty good at the center of the frame, though some blurring is noticeable in the corners strongest in the top corners.

There's also a small amount of coma distortion around the leaves against the sky, and a little chromatic aberration visible in areas of high contrast. At full telephoto, blurring is less visible in the corners of the frame, and only a little chromatic aberration is still present around the white trim on the house.

The camera's 2x digital zoom did a good job of preserving detail despite the digital enlargement. Subcompact cameras tend to sacrifice optical quality for compactness, a factor that is at work here, but performance is good for standard snapshots.

Macro A very small macro area with good detail and high resolution at the center of the frame. Flash performance is better than average this close, but still uneven. Detail and resolution were both very good at the center of the frame, with good definition in the fibers of the dollar bill.

The corners get a little blurred, though, losing some of the fine details. Most cameras have some softening in the corners in macro mode, especially sub-compacts: The Sony T77 really outperforms its class in this shot. The DSC-T77's flash throttled down fairly well for the macro area, though the exposure is uneven with shadows in the corners. Distortion About average barrel distortion at wide angle, high pincushion at telephoto.

At the telephoto end, the DSC-T77's 0. Distortion is the tendency for the lens to bend straight lines outward like a barrel -- usually at wide angle or inward like a pincushion -- usually at telephoto.

Chromatic aberration Moderate levels at both wide angle, a bit less at telephoto, though with bright coloration at each setting. Chromatic aberration is moderate at wide angle, but a bit lower at telephoto. For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused. Battery Slightly below average battery life. Panasonic G95 Review.
