HDR and ultra xdr camera

NexPG

Do you enable HDR in the camera, as well as ultra xdr? Do these functions affect shutter lag and blurred photos? What exactly does ultra xdr do? Don’t photos look better without these features? Ideally, I would like there to be a photo mode without any processing, noise reduction or smoothing at all, this is especially disgusting when you use a zoom camera.

Hdr and ultra hdr helps to capture intensive lights and dark so the image looks detailed and sensor helps to gather more light so the image looks more bright and vivid well in nothing phone 2 ultra xdr and hdr works hit or miss

HDR does effect shutter lag and that’s due to the reason of how HDR works:

If you tap the shutter button, your phone doesn’t take just one photo, it takes eight photos in a rapid row. Each of them differently exposed from strong overexposire to strong underexposure. Those eight images are combined into one be are processed in a way so that the underexposed images retain details in bright areas like clouds and the overexposed images will brighten up otherwise dark areas.

Now while the phone does shot these eight picture extremely fast, the image series is still prone to movement, both from the phone but as well as the scenery of your subject, for example if you take a picture of people dancing or take a picture out of the window from a moving car. If lighting conditions are worse, especially indoors or after sunset, you’re nore likely to encounter blurry images, because the exposure times are longer and the phone needs more time taking the required row of images.

So indoors, at night or when taking moving objects, it’s typically better to just disable HDR. Regarding XDR: I have to admit that I don’t really get how it works, it seems like an improved HDR method, but I don’t know if it either takes more shots (like ten) or if it just gets more processing time in order to get a slightly better HDR quality.

Coldpaw Do you keep it on or off?

Coldpaw

NexPG Depends on situation, in low-light I rather keep it off and when theres quite some movement or action in the scene I also disable HDR.

Only this is option not good.

I keep it off and will edit after take the photo.

Still, what is preferable for stable, beautiful photos? Do HDR and XDR work quite stable or are they often very slow and blurry? What opinion did the majority have?

NexPG try to click without hdr and xdr only enable when you need otherwise picture quality is better is normal mode

NexPG As I said it completely depends on the situation. In scenes with very high contrast scenarios, as a sort of worst case scenario you are actually shooting against the sun, with lots of shady and dark areas, but very bright areas as well, HDR helps to create a photo which shows lots of details in both dark and bright areas - that wouldn’t be otherwise possible to that extend with a standard SDR image.

You should just be more mindful to movement, both of your phone as well of the scene you are photographing. If the scene is too dark, let’s say inside a restaurant of maybe even a night club, just disable HDR in order to further prevent any sort of ghosting. If the phone switches to night mode anyways, which can be seen by the moon symbol, you’ll have to hold the phone extra still anyways.

XDR is all about how we see images. Usually, we see images in SDR (Standard Dynamic Range). Let’s say SDR has a range of 0-100, where 0 represents black, 100 represents white, and all other colors fall in between.

XDR expands this range beyond 100. For example, it might extend to 200, where 0 represents black, 200 represents white, and all other colors fall in between. This is possible because new display devices support a wider range of brightness, thanks to improved peak brightness.

You can see this in action by observing the brightest part of an XDR image (usually a light source), which is much brighter than in usual SDR images.

However, you can only experience this difference when viewing these images on HDR-supported displays. (Note: HDR in cameras and displays are different.)
