Re: Foto Zoom
Periandro Hawkins
Thanks for comments. After choosing another key photo and saving the image it stays zoomed in And does not return to normal. Reverting is not a solution because this will revert also back to original key photo.
What you're experiencing is expected behavior. While you're selecting your key photo, the picture does zoom in a bit. Once you have selected the photo and save your changes, the image will return to normal, and no longer be zoomed in. If it is, you can go back into the edit menu and tap the red "Revert" option to bring it back to the original.
The top-of-the-line DermLite Foto II Pro dermoscopy lens, a world-class 3GEN optical design, has been designed for those who wish to capture the highest quality dermoscopic images using any 2/3 frame or full-frame Canon or Nikon DSLR.
Featuring polarized and non-polarized illumination, a 6-element lens design for superior resolution, zoom, camera-controlled automatic polarization change, Foto II Pro is the go-to device for situations where only the best dermoscopic image quality will suffice.
The 15 Pro has a tried and true 3x telephoto camera like previous models. But the 15 Pro Max has a new 5x telephoto camera that's made with multiple prisms and some clever engineering.
This was taken with the iPhone 15 Pro Max's 5x zoom camera.
One nifty addition to both phones is the ability to change the focus after you take a portrait photo. Check out this '90s grunge band photo of me and my pal Beacham. I can change the focus from me to him after I take the picture. This is going to be a killer feature for parents.
We put the Samsung Galaxy S23 Ultra through our rigorous DXOMARK Camera test suite to measure its performance in photo, video, and zoom quality from an end-user perspective. This article breaks down how the device fared in a variety of tests and several common use cases and is intended to highlight the most important results of our testing with an extract of the captured data.
With a DXOMARK Camera score of 140, the Samsung Galaxy S23 Ultra achieved a very good result in our camera tests. It offered good performance across pretty much all test attributes, without major drawbacks in any area, making it a great smartphone imaging allrounder. Still images featured excellent detail in bright light and a fairly wide dynamic range across all light levels. Please note that still-image testing was undertaken at the default 12MP resolution. The camera also allows for capture at higher image resolutions.
Effective stabilization and a fast and accurate autofocus meant that the Galaxy S23 Ultra also did well for video. White balance in low light left some room for improvement, though. Compared to the predecessor S22 Ultra, the Samsung engineers managed to achieve improvements in several areas, including video stabilization, slightly better zoom, noticeably better video exposure, and improved autofocus speed in bright light. Please note that all comparisons with the S22 Ultra in this review were made with the Snapdragon version of that device. The S23 Ultra only comes as a Snapdragon variant. Unlike for previous generations, there is no Exynos-powered version.
In low light, the S23 Ultra produced good exposure with a quite wide dynamic range, capturing decent detail in both the highlight and shadow regions of the frame. In terms of color, the engineers opted for maintaining some of the atmosphere that is produced by dim warm light sources, delivering overall nice color in low light. Many competitors tend to take a more neutral approach to white balance in low light, but what you prefer is pretty much down to personal taste.
In our tests, the Samsung Galaxy S23 Ultra performed well for still imaging, capturing impressively high levels of detail in landscape shots. The wide dynamic range is a slight improvement over the predecessor S22 Ultra, and ensured good highlight and shadow detail, even when capturing difficult high-contrast scenes. On the downside, in backlit portrait scenes, a lack of contrast on faces resulted in an unnatural look, and in dim light conditions, image noise could become quite intrusive.
The Galaxy S23 Ultra did a good job of capturing detail in macro mode. In addition, macro images featured pleasantly bright colors. On the downside, noise was quite noticeable when viewing the images up close, and a visible regression compared to the S22 Ultra was noticeable.
Exposure is one of the key attributes for technically good pictures. The main attribute evaluated is the brightness of the main subject through various use cases such as landscape, portrait, or still life. Other factors evaluated are the contrast and the dynamic range, eg. the ability to render visible details in both bright and dark areas of the image. Repeatability is also important because it demonstrates the camera's ability to provide the same rendering when shooting several images of the same scene.
In terms of exposure, the Galaxy S23 Ultra is a slight improvement over its predecessor the S22 Ultra. In our tests, dynamic range was slightly wider on the new model, and in these samples, you can see the S23 Ultra preserved a touch more detail in the clipped background of the image.
The very slight improvement compared to S22 Ultra was also visible in our contrast entropy tests in the lab. For this test, we vary the brightness of a backlit panel of grayscale blocks to increase or decrease the brightness difference to a Dead Leaves chart in the same test setup. As you can see, the S23 Ultra delivered slightly better entropy than the comparison devices across pretty much all light conditions.
Exposure instabilities were an issue though, with noticeable exposure differences between consecutive shots of the same scene. In comparison, the iPhone 14 Pro was much more consistent. Tone compression on faces was another weakness in terms of exposure. In this sample contrast is low on the faces, resulting in an unnatural effect.
Color is one of the key attributes for technically good pictures. The image quality attributes analyzed are skin-tone rendering, white balance, color shading, and repeatability. For color and skin tone rendering, we penalize unnatural colors but we respect a manufacturer's choice of color signature.
Autofocus tests concentrate on focus accuracy, focus repeatability, shooting time delay, and depth of field. Shooting delay is the difference between the time the user presses the capture button and the time the image is actually taken. It includes focusing speed and the capability of the device to capture images at the right time, what is called 'zero shutter lag' capability. Even if a shallow depth of field can be pleasant for a single subject portrait or close-up shot, it can also be a problem in some specific conditions such as group portraits; Both situations are tested. Focus accuracy is also evaluated in all the real-life images taken, from infinity to close-up objects and in low light to outdoor conditions.
The Samsung Galaxy S23 Ultra was overall a very good performer for autofocus, with fast capture in bright light and under indoor illumination, even in high-contrast conditions. This is a significant improvement over the S22 Ultra, which took longer to capture images in outdoor conditions.
The delayed capture in low light is illustrated in this sample. In this scene, the trigger is actuated as the person passes by the wall. The iPhone did an excellent job and captured the image immediately. Both Samsung devices were noticeably slower and captured the image only after the subject had moved closer toward the camera.
Texture tests analyze the level of details and the texture of subjects in the images taken in the lab as well as in real-life scenarios. For natural shots, particular attention is paid to the level of details in the bright and dark areas of the image. Objective measurements are performed on chart images taken in various lighting conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The charts used are the proprietary DXOMARK chart (DMC) and the Dead Leaves chart.
Noise tests analyze various attributes of noise such as intensity, chromaticity, grain, structure on real-life images a-cs well as images of charts taken in the lab. For natural images, particular attention is paid to the noise on faces, landscapes, but also on dark areas and high dynamic range conditions. Noise on moving objects is also evaluated on natural images. Objective measurements are performed on images of charts taken in various conditions from 1 to 1000 lux and different kinds of dynamic range conditions. The chart used is the Dead Leaves chart and the standardized measurement such as Visual Noise derived from ISO 15739.
Overall, the Samsung Galaxy S23 Ultra did a good job at controlling image noise levels and balancing it with texture. However, in some scenes, such as the one below, our testers observed unexpectedly high luminance noise.
The artifacts evaluation looks at lens shading, chromatic aberrations, geometrical distortion, edges ringing, halos, ghosting, quantization, unexpected color hue shifts, among others type of possible unnatural effects on photos. The more severe and the more frequent the artifact, the higher the point deduction on the score. The main artifacts observed and corresponding point loss are listed below.
We found a variety of image artifacts in our S23 Ultra sample shots, the most prevalent being fusion artifacts, like the ones visible in this scene. This said, the mixed low-level lighting made for difficult conditions to shoot in.
Bokeh is tested in one dedicated mode, usually portrait or aperture mode, and analyzed by visually inspecting all the images captured in the lab and in natural conditions. The goal is to reproduce portrait photography comparable to one taken with a DLSR and a wide aperture. The main image quality attributes paid attention to are depth estimation, artifacts, blur gradient, and the shape of the bokeh blur spotlights. Portrait image quality attributes (exposure, color, texture) are also taken into account.
