Several camera manufacturers  offer built-in multi-exposure HDR features. For example, the [[Pentax K-7]] DSLR has an HDR mode that makes 3 or 5 exposures and outputs (only) a tone mapped HDR image in a JPEG file.<ref>{{cite web|last=Howard|first=Jack|date=May 20, 2009|title=The Pentax K-7: The Era of In-camera High Dynamic Range Imaging Has Arrived!|url=http://www.adorama.com/alc/0011608/blogarticle/The-Pentax-K-7-The-era-of-in-camera-High-Dynamic-Range-Imaging-has-arrived|url-status=dead|archive-url=https://web.archive.org/web/20141223124601/http://www.adorama.com/alc/0011608/blogarticle/The-Pentax-K-7-The-era-of-in-camera-High-Dynamic-Range-Imaging-has-arrived|archive-date=December 23, 2014|access-date=18 August 2009|work=Adorama Learning Center|publisher=[[Adorama]]}}</ref> The [[Canon PowerShot G12]], [[Canon PowerShot S95]], and [[Canon PowerShot S100]] offer similar features in a smaller format.<ref>{{cite web|last=Mokey|first=Nick|date=September 14, 2010|title=Canon PowerShot G12 picks up HD video recording, built-in HDR|url=http://www.digitaltrends.com/photography/cameras/canon-powershot-g12-picks-up-hd-video-recording-built-in-hdr/?news=123|access-date=June 12, 2020|work=[[Digital Trends]]}}</ref> Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the emphasis being on creating a realistic effect.<ref>{{cite web|last=Heiner|first=Steve|date=2017|title=Intermediate: Balancing Photo Exposures with Active D-lighting|url=https://www.nikonusa.com/en/learn-and-explore/a/ideas-and-inspiration/balancing-photo-exposures-with-nikons-active-d-lighting.html|access-date=August 2, 2017|work=Nikon Learn and Explore|publisher=[[Nikon]]|department="Ideas and Inspiration" section}}</ref>

Some [[smartphone]]s provide HDR modes for their cameras, and most [[mobile platform]]s have apps that provide multi-exposure HDR picture taking.<ref>[[Android (operating system)|Android]] examples: {{cite web|title=Apps: HDR mode|url=https://play.google.com/store/search?q=hdr%20mode&c=apps|access-date=June 12, 2020|work=Google Play}}</ref> Google released a HDR+ mode for the [[Nexus 5]] and [[Nexus 6]] smartphones in 2014, which automatically captures a series of images and combines them into a single still image, as detailed by [[Marc Levoy]]. Unlike traditional HDR, Levoy's implementation of HDR+ uses multiple images underexposed by using a short shutter speed, which are then aligned and averaged by pixel, improving dynamic range and reducing noise. By selecting the sharpest image as the baseline for alignment, the effect of camera shake is reduced.<ref>{{cite web |url=https://ai.googleblog.com/2014/10/hdr-low-light-and-high-dynamic-range.html |title=HDR+: Low Light and High Dynamic Range photography in the Google Camera App |author=Levoy, Marc |date=October 27, 2014 |website=Google Research |access-date=14 December 2022}}</ref>

Some of the sensors on modern phones and cameras may combine two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.{{Citation needed|date=November 2017}}
