Converting Hif to Jpeg on computer

BreegeEnglish — Sat, 21 Oct 2023 20:59:05 GMT

I somehow today saved about 300 photos in HIF. I've never done that before. would anyone know how to convert HIF to Jpeg on a computer. Very frustrated

Do you mean HEIC or HEIF?

Are you using a Macintosh? If so, you can use Finder Quick Actions to perform the conversion:

Select all the HEIC or HEIF you wish to convert
Right-click or Control-click the selected items
Choose Quick Actions > Convert Image
In the Conversion options, choose JPEG

The Canon DPP software will do the conversion if they were produced by a Canon camera. DPP is free to download from the Canon support page for your camera if your camera is a Canon.

The Apple Photos.app included with macOS will do the conversion.

If your camera also saved a raw file, Canon DPP will convert the raw file to JPEG.

ImageMagick might do the conversion depending upon which libraries were included when it was built.

Some versions of gimp free software will do the conversion.

Some Canon cameras will do the conversion. It is in the playback menus of the camera.

I usually work in RAW and then convert to jpeg, depending on what the image is. I can't get DPP4 to convert for me. I've been trying that. I also tried to upload an image here and it wouldn't take it.

Did you ever find a solution for this? im having the same issue and i dont think i have the knowledge to fix it

You need to answer the same questions we posed the OP.

Did you try any of the solutions already presented?

The first thing you need to do is go into the "Shooting 2" menu and disable "HDR Shooting - HDR PQ". Shooting 2 is where it is in all of the R manuals I have, so I'm confident you will find it there even though you didn't mention which R you own. This will prevent the HIF files from being created in the first place. Next you need to download/install DPP 4 and get acquainted with the "Batch Process..." command in the File pulldown. You will have to have your HIF files loaded and selected in DPP. I've used other converters and DPP, albeit slower, does the best job.

Depending on how many HIF files you have, it may take some time. When I use HDR PQ, I don't save to HIF in camera but convert to HIF in DPP after editing my Raw files. So my conversion is from Raw. The screen shot was from another post about HIF to JPG that I posted.

I've used this method (Batch save and Convert) to convert HDR photos to JPG, but they all end up much lighter than the original, both viewed in DPP. The exported JPG looks the same in DPP, ACDSee and Windows 11 Photo viewer. I have tried selecting the option to "Embed color profile" and not embedded it. Both results are the same.

To get the resulting JPG to look anything like the original on the same HDR monitor, I have to edit the JPG and reduce the brightness -30eV points.

I cannot find a way to fix this in DPP.

I can also not edit the HDR photo. All the brightness and colour settings are greyed out on the "Tool palette". I have DPP 4.19

Can anyone help please?

Further to the comment above, the conversion applies some sharpening as well.

There is no control over these items (that I can find). The same changes appear when using the in-camera HIF-> JPG conversion.

I have a Canon R7.

I expect that the problem is the icc profile. A particular icc profile is required by the standards when making PQ HDR image files, but it appears to me that the profile is implicit and not explicitly included in the HIF files. Canon might improve DPP by adding a possibility of explicitly adding an ICC profile during conversion.

When I do batch conversion of image formats, I usually use graphicsmagick free software and use exiftool to copy metadata tags. Canon could improve DPP by adding support for standard IPTC metadata tags and standard Metadata Working Group tags. Usually Canon is very good about supporting standards, but has fallen behind in DPP.

I have built from source https://github.com/google/jpegli which is related to https://github.com/libjxl/libjxl/tree/main/lib/jpegli on both my Debian Linux machine and on my iMac. I have used this to create an icc profile that works for converting HIF files to other formats. I expect that such an icc profile might be available elsewhere.

I replied to a similar question once before: https://community.usa.canon.com/t5/Camera-Software/Ultra-HDR-formatted-JPEG-workflow-from-RAW/m-p/494423

Information about the standard is at https://en.wikipedia.org/wiki/Perceptual_quantizer and at https://en.wikipedia.org/wiki/Rec._2100

https://manpages.debian.org/testing/libjxl-tools/cjpeg_hdr.1.en.html

To attach a PQ profile to an image without a colour profile (or with a different colour profile), the following command can be used:

``` build/tools/decode_and_encode input RGB_D65_202_Rel_PeQ output_with_pq.png 16 ```

Similarly, to attach an HLG profile, the following command can be used

``` build/tools/decode_and_encode input RGB_D65_202_Rel_HLG output_with_pq.png 16 ```

This is what I did, but I have low confidence that it would work for others.

I'm not sure why you are having this problem. Mine convert fine with no need for editing other than what picture style applies ("Standard"), which I have made no changes to so it's "stock" and whatever Canon provides.

Here are a couple of screen shots strait from conversion with no post editing. Yes, there are some color variations, but that is a result of going from a 10bit HIF HDR to 8bit JPeG. Please click the thumbnails to expand or view full screen.

HDR HIF in DPP 4.

Converted HIF to JPeG in DPP 4.

Sorry I can't be of more help, other than to say I have a different experience with this process.

I'll just add that this particular original shot was taken with an EOS R5 and RF 100-500L under a 60w lamp. 167mm, 180th, f/5, ISO 1600. But that shouldn't make a difference in the batch conversion, so it's just info some folks like to see 🙂

Where I have seen the problem is when I have made a photo of a Northern Cardinal bird in bright sunlight.

Even with -2/3 exposure compensation the red channel is clipped in DPP unless I change to HDR PQ mode or increase the dynamic range. Then, if I save a JPG from a HIF in DPP it does not include the PQ ICC profile and the image is too dark. If I add an HDR PQ ICC profile to the JPG file, then the colors display as expected.

I expect that this will only need to be done if some of the values are clipped. If no values are clipped, the the HIF and JPG should be the same except for the ICC curve. If the red value for a pixel has a value of 600 in the HIF file, it must somehow be reduced to 256 when converting to JPG. The choices for reducing the red pixel value might include darkening the entire image or clipping all values greater than 256 to 256 or applying a different gamma curve to compress the dynamic range.

If Canon were to explicitly add a redundant ICC profile to the JPG made from a HIF file then other software would display it better. But I use only Debian Linux and macOS and never Windows and I might be wrong.

Thanks for the details. I agree with your summary, that the problem is the lack of an embedded icc profile in the HIF files. The profile is also not embedded in the JPGs. When viewing the files in other tools, e.g. ACDSee, one can set the default profile to use when it's missing from a photo, but only one. I'll try your method to embed the profile.

Thanks Newton. Interesting that there is little brightness difference in your photos. The colour difference is expected, as you said.

EDIT:

I thought I agree with your summary, that the problem is the lack of an embedded icc profile in the HIF files. However, looking at the file in GIMP (not converted), file properties show the colour profile as "RGB color: BT.2020 sRGB-TRC RGB".

GIMP doesn't display this well at all, even converted to sRGB. It's also washed out like in ACDSee.

I found an Full HDR ICC profile online "HDR UHDTV Wide Color Gamut Display Rec. 2020)". Applying that in ACDSee as the default input profile, makes the HDR PQ photos appear much closer to what I see in DPP. I probably need the right profile, using the method you tried.

This test suggests that the HIF file colour profile isn't being read by ACDSee.

I'll experiment with your method.

The JPG export is a separate problem. It's possibly the mapping from the HDR to SDR is a little different to what I expect.

u can use irfanview also for converting . i use batch process in it.
