This image of galaxy pair VV 191 includes near-infrared light from Webb, and ultraviolet and visible light from Hubble." "We got more than we bargained for by combining data from NASA's James Webb Space Telescope and NASA's Hubble Space Telescope! Webb's new data allowed us to trace the light that was emitted by the bright white elliptical galaxy, at left, through the winding spiral galaxy at right-and identify the effects of interstellar dust in the spiral galaxy. Here, Webb interdisciplinary scientist Rogier Windhorst and his team discuss their observations. This article highlights data from Webb science in progress, which has not yet been through the peer-review process. Credit: NASA, ESA, CSA, Rogier Windhorst (ASU), William Keel (University of Alabama), Stuart Wyithe (University of Melbourne), JWST PEARLS Team Blue was assigned to two Hubble filters, ultraviolet data taken in 0.34 microns (F336W) and visible light in 0.61 microns (F606W). In this image, green, yellow, and red were assigned to Webb’s near-infrared data taken in 0.9, 1.5, and 3.56 microns (F090W, F150W, and F356W respectively). ![]() Webb’s near-infrared data also show us the galaxy’s longer, extremely dusty spiral arms in far more detail, giving them an appearance of overlapping with the central bulge of the bright white elliptical galaxy on the left, though the pair are not interacting. As a result, they were able to identify the effects of interstellar dust in the spiral galaxy. You can also set it to the default on your smartphone.Researchers traced light that was emitted by the bright white elliptical galaxy on the left through the spiral galaxy at right. When you add images to an album, to upload them in High Quality, make sure the “High Quality” option is enabled. If you’re serious about having the highest quality images possible on Facebook, the best thing to do is upload your images to a photo album, and then share them from there. RELATED: How to Stop Facebook from Uploading Low-Quality Photos and Videos from Your Phone High Quality is only available when you upload images to a photo album. Normal Quality is used for almost everything (posting an image as a Status Update or Profile Picture, for example). For this reason, rather than compress images yourself, we recommend uploading the highest quality JPEG you can.įinally, Facebook has two separate qualities of uploads: Normal Quality and High Quality. In fact, they compressed it even more than when I uploaded the 2.4 MB version. Unfortunately, even when I uploaded photos that fell under this limit, Facebook still compressed the image. Through a bit of experimenting, I’ve found that Facebook compresses the highest quality versions of your images to just under 500 KB. As you can see below, Photoshop’s defaults automatically convert the color profile to sRGB. If you do have an image in a non-sRGB color space, you can either let Facebook take care of the conversion, or open the image in your image editor of choice and save it using the default JPEG settings. You can see here that the selfie I shot with my iPhone is in sRGB, so I don’t need to change anything. You can check what color space a photo is using by viewing its metadata. ![]() Realistically, if you have images that aren’t in the sRGB color space, you probably made a deliberate decision at some point to use something with a wider color gamut and know what you’re doing. If you take a photo with your smartphone or export one you take with your DSLR from Photoshop, Lightroom, or any major editing app, it’s going to be in the sRGB color space. sRGB is the color space used for 99% of JPEGs. The good news is, you probably don’t have to change much here. Facebook uses sRGB-the standard color profile for most displays. Next, you want to upload photos in the right color space. That leaves us with one ideal size: 2048 pixels wide. For photos, we can safely ignore the two smaller options they’re just ludicrously small. Facebook recommends three sizes: 720 pixels, 960 pixels, and 2048 pixels wide. Plus, when you adjust your own photos, you have the option of doing a little cropping instead of resizing. This minimizes how much resizing Facebook does. You can, however, take steps to make them look better.įirst, you need to upload them in the right size. Let’s make one thing clear your photos are never going to look objectively great on Facebook. When I went into my Photos collection on Facebook, I was able to grab a 1938 by 1292 pixel version that was 348KB, but even that represents some seriously aggressive optimizing!
