HDR stands for Excessive Dynamic Vary and is a setting accessible on a number of Fujifilm cameras, together with the X-T4. HDR entails merging separate pictures collectively to create a single JPEG file so as to present the utmost quantity of dynamic vary attainable out of your picture.

While you set your Fujifilm dial to HDR and press the shutter button, the digital camera will take three pictures directly. Photograph #1 will use the publicity settings you made on the time you took your shot. Photograph #2 will likely be underexposed and Photograph #3 will likely be overexposed. Then, the digital camera will merge collectively these three pictures and save the consequence to the SD card as a single JPEG picture.

The X-T4 lets you specify the publicity settings for the HDR picture:

HDR 200%: Units HDR bracketing to 1 cease of publicity.

HDR 400%: Units HDR bracketing to 2 stops of publicity.

HDR 800%: Units HDR bracketing to a few stops of publicity.

HDR AUTO: The digital camera robotically chooses between HDR 200%-400% primarily based on the lighting of the scene.

HDR 800%+: This can be a extra excessive model of HDR 800%. From what I used to be in a position to check within the video, it seems to mix the features of HDR 800% with D Vary Precedence set to STRONG. In response to Fujifilm, through the use of HDR 800%+, the “camera settings are adjusted for maximum variation in dynamic range.”

HDR 800%+ Is Very Noticable

Whereas all the opposite HDR settings (200%, 400%, and even 800%) don’t have as a lot noticeable impact on the shadow element of the photographs, the 800%+ actually does. Virtually an excessive amount of, in reality. It usually has a ‘muddy’ look to it when you’re not cautious.

To assist alleviate this, I like to recommend setting your Readability to +3 and your Sharpness to +2 to convey again some ‘punch’ into the picture when utilizing HDR 800%+. These readability and sharpness settings may be present in your digital camera menu.

However RAW Information Are Additionally Affected!

Kind of. Should you shoot in HDR mode along with your digital camera’s output setting to (Superb/Regular) + RAW, then you’ll get two recordsdata: 1.) an HDR-produced JPEG and a couple of.) a RAW file.

The file measurement of the RAW is 3X bigger than a standard RAW file from the digital camera. It is because the RAW file really incorporates three separate pictures inside the one .RAF file!

Included is the primary picture that you simply shot, which relies on the publicity settings on the time you took the picture. Then, a second picture that’s underexposed by nevertheless many stops you set HDR. After which, there’s a 3rd picture that’s overexposed.

Nevertheless, if you open up that single .RAF file in Lightroom, Photoshop, Seize One, and so forth, it’s only seen as one single file. And solely the information within the first picture contained in the file is utilized by this system.

It seems that there’s an official identify for this sort of Fujifilm file: Fujifilm HDR RAF. Nevertheless it will get even stranger. On the Adobe website, they point out there’s a setting you can make in Lightroom the place you change the Fujifilm HDR RAF into an Adobe DNG file.

You should be within the Library module. Then, you choose the picture you wish to convert, go as much as the Library menu merchandise, after which select “Convert Photo to DNG.” You’ll see a dialog field provide you with a checkbox that claims, “Embed original Raw file.”

Should you tick that field, supposedly Adobe will take info from all three of these embedded pictures inside your one uncooked file and produce a DNG from that. I ran some checks doing this and sadly I discovered completely no distinction utilizing the embedded authentic choices checkbox chosen or not chosen. In each circumstances, the ensuing pictures appeared similar.

It could be fascinating to see if anybody has discovered a solution to extract out the three separate RAW recordsdata from the one .RAF picture produced by the digital camera. This manner, all three recordsdata might be imported individually into Lightroom or Photoshop and merged along with far higher management.

After all, the Fujifilm digital camera presents a really comparable and truly a lot better course of through the use of the Publicity Bracketing characteristic that’s additionally included within the digital camera. Nevertheless, the HDR characteristic was necessary sufficient to Fujifilm to incorporate on the very high dial in a distinguished place, and it’s actually price exploring in higher element.

Joyful taking pictures!
