DNG Files Underexposed Upon Import
AnsweredHi, I just purchased ON1 Photo Raw 2023 w/ Plugins and can't figure out why my unedited DNG files are quite a bit underexposed upon importing. It appears proper for a second and then turns dark. The DNG files are from my Apple iPhone 13 Pro Max.
My computer is a loaded late 2021 MacBook Pro M1 Max, 64GB 4TB running OS Ventura 13.0 Thanks. Ray

What you see at first is the embedded jpg created by the camera. What you see second is the actual RAW data being interpreted by Photo RAW. Try Clicking tha Auto AI button. It tries to match the RAW file's look to the embedded jpeg.
You might want to download and at least browse through the User Guide.

Thank you Brian, I tried AI Auto under Develop which caused the photo to be overexposed more. I can howevever, use Manual to bump up the Exposure & Saturation. This places the exposure pretty much as the original. These photos are in a folder which appears to have all their metedata. I tried another test opening up the same photo in Apple Photos > Edit > Extensions > ON1 Portrait AI in which the photo imported properly. I also, repeated this with ON1 NoNoise AI & Effects in which all imported properly. I then thought there must be something missing in the metadata between Apple Photos & my seperate folder but, I don't see anything missing. I want to use ON1 Photo Raw 2023 for the most part as a standalone without using Apple Photos simply due to most of my photos being in folders. Obviously there is something going on between using my photo folder's and Apple Photo. It's a head scratcher..... LOL. Thanks again for your help, I sincerely appreciate it. Ray

This places the exposure pretty much as the original. What you are comparing to is not the original. the DNG data you see in Photo RAW is the original. The exposure you see that you like is the jpeg the camera produced for you according to its settings. If Auto AI isn't giving you the results you want you'll just have to edit the photo to your liking.
What you see when using the Portrait AI or NoNoise AI plug-ins are Apple Photos' interpretation of the photo before it gets sent to them. You're comparing apples to oranges, they are going to be different.
Metadata has nothing to do with what is going on.
Once you come up with the settings you like you can save them as a Preset to be applied to new photos as a starting point which will reduce your workload.

Thanks Brian, This places the exposure pretty much as the original. Yes, I am comparing the original raw DNG photo O.S. of ON1 to the original raw DNG photo when brought into ON1. When comparing both, the DNG photo with it's JPEG photo O.S. of ON1, they're both the same.
What you see when using the Portrait AI or NoNoise AI plug-ins are Apple Photos' interpretation of the photo before it gets sent to them. You're comparing apples to oranges, they are going to be different. I agree, I was just trying different scenario's. With that being said, exposure was and is the same when brought in ON1 using Apple Photos.
As of right now, I'll just have to adjust the DNG raw photo within ON1. Thanks. Ray

I'll be happy to take a look at one of your DNGs if you want to make it available for download. Post it to someplace like Dropbox or WeTransfer then post the download link here. I'll look at it when I get home tonight.

Thanks Brian, I'm not sure how to send it to you as a download due to never using either Dropbox or WeTransfer.

I checked out WeTransfer..... The following is a link to the file. Thanks for the help.

I have your files although I do not know what an .aae file is. I'll post back in a few after I've had a chance to catch up with things and take a look at it.

Your file looks normal to me. It matches the histogram and is what I would expect from an underexposed image. ISO 50, 1/3000th sec, ƒ/1.5. For a daylight scene like that ISO 100, 1/100th s, @ƒ/8 would be my starting point. Your shutter speed is 5 f-stops below that and even though you used a wide aperture it isn't 5 stops worth. The ISO 50 drops the exposure another stop.
You can try different Camera Profiles even though there aren't any for the iPhone. Neutral and Portrait brighten it up a bit. Be aware that Camera Profiles are just LUTs that are applied at the beginning of the rendering process. Linear RAW (which is even darker and flatter) shows you the actual RAW data after being demosaiced by the program so we can see it. It tells the program to not use any Profile/LUT.

I think you've got a good starting point. I did this in just a couple of minutes with a Preset of my own

I found out what the .aae file is. It is Apple Photo's version of an .on1 file. It contains the adjustment data that was applied by Apple Photo.

Thanks Brian, great job on the pic, it looks really nice. Your absolutely right, ISO 50 wasn't a good starting point. I took quite a few shots using auto due to the busy pull off's along the Blue Ridge Parkway in Tennessee. I may have left the WB setting on cloudy as well from the day before. I usually shoot with ISO 100 and try to not go above ISO 400 at around 5000k - 5500k. I'm more of a video guy in which I usually follow those settings along with following the 180° rule, with ND's. I did contact ON1 Tech Support the same day of my O.P. (See below). I'd like to add, I'm really glad to see that ON1 responds back with its customer's along with covering their software in quite a thorough manner with manual's and video's. Additionally, I'm thankful for this ON1 forum and really appreciate your time in helping me understand my situation. I'll just have to tweak those DNG files first with a little exposure and WB. So far, I'm really loving the software. Thanks again. Ray 👍😊
Read from the bottom up....due to being an email.

Here's a link to a Preset I created from your file if you'd like to see how I processed it. Be sure to look at the Blending Modes on the Local Adjustments. They are key to the Preset I started with.

Awesome! Thank you for sending your preset, definitely a keeper. That's really nice to be able to create your own as well as viewing all the blending modes & adjustments. I can see that custom preset's will be quite a time saver. I looked at all of your settings, especially your Local Adjustments of your Highlights & Shadows along with the blending modes. I'll make sure I start out with Local Adjustments when starting an edit. You definitely gave me some more insight to this software! Thanks again, I sincerely appreciate all your help and time. Ray 👍😊

HI Raymond & Brian,
I can confirm it's not just Apple DNGs that have this issue. I have a Samsung S22 Ultra and the RAW DNGs appear the same way in On1. Dark. I am guessing the smartphones do their magic to the JPGs to produce a nice picture. I am not looking forward to having to individually edit each picture to get it to the point to viewability and then add effects.
I do wonder why Windows can render the DNGs the same as the JPG produced from same shot. I have Adobe PSE as well that comes with Camera Raw. This does a pretty good job with the Auto AI to get the image close to where it should be. Hopefully On1 will enhance this feature for smartphone DNGs.

Hi Brian, I lost this information somewhere along the line. If you still have it available, would you please send it to me and/or post it here? Thank you, appreciate it. Ray

Sorry Ray, I don't have a copy anymore. If you used it on the photo above you can create a new one from it.

Here is how I started with my own Preset.
- Set Camera Profile to Linear RAW
- Go to Effects
- Add 2 Tone Enhancers both with Luminosity Masks, 1 inverted so you have a mask for highlights and one for shadows, and set both Blending Modes to Soft Light.
- Add a Sunshine filter
- Add 2 Local Adjustments, again with highlight/shadows masks and set their Exposure sliders to 0.
That is what I started with. I have a Preset with those steps in place that I often use as a starting point for my photos. The reason for the 2 Local Adjustments is to control the strong changes caused by the Soft Light Blending modes. If something is too dark use the Shadows Local Adjustment to fix it. The same for the brightness only use the Highlights masked LA.

Thanks Brian.... I copied these steps for future reference. I'm also going to go through the process and create a Preset with those steps. Thank you for your help and taking the time in posting this great starting point, appreciate it. Ray 👍😊

I have same problem with DNG files from my iphone 12pro . (a bit underexposed upon importing. It appears proper for a second and then turns dark). i have tried to adjust it but it not easy to get the desired result. In Adobe lightroom it is no problem with this file . I get to keep lightroom and not buy on1 as I have many pictures from the mobile and it becomes too much work o get it good picture quality.
