A friend recently scanned my favorite files into Affinity I and I cannot import them into Aperture because the program does not recognize .dng files. Is there a way to downsize these huge (60MB) files and import them to Aperture?
At my age, I'm not interested in learning another photo software program and I don't really like Affinity or understand the "develop image" command. Can someone help me here?

There are several .dng converters online for free. Google .dng converter. It may take a while to convert as it's online and you may have to do one at a time. It might be better to ask your friend to convert them into a .jpg or .tif file for you.

Photopea is free and will handle .dng files. I have it on a Mac but I think it will work on a pc as it is web based.

.dng files are adobe's generic version of a raw file. every camera brand has its own raw format. Adobe strips all the brand bits and converts them them to .dng which stands for digital negative.

Thank you very much.

Ask your friend to convert them to JPEG and send you the JPEGs (*.jpg) instead.

I actually have Affinity software, so can I do that myself from the .dng files he gave to me?
Thanks again, you always have intelligent answers to my questions.

I tried to do a Google search on this. You can export photos in a different format, however it doesn't seem that batch exporting is possible. Someone who actually uses the software can possibly help. You can do this in Lightroom or Photoshop if you have access to those.

Aperture is DEAD! Not supported anymore! You would be wise to get your files out of there and download them to some where else. One day you might not be able to access them, if you change platforms like getting a new computer. I don't mean like tomorrow or else, but the sooner the better. You can download your files to another external drive and then back that drive up with another one. Just saying.

In Affinity, under File, you can Export them (as opposed to save) and it will bring up a menu to 'save as' options: one is jpeg w/ slider for size. Hit that and it will bring up your computer site as to where to save them (your choice) of file in computer.

Open Affinity Photo without any photo in it. Then click on File at the top and then New Batch Job. Click on Add to add all of your DNG files. On the right you can choose what format to convert them to and where to save them. You can batch convert them to multiple formats such as TIFF and/or JPEG. These should work in Aperture.

I agree that Aperture is dead (my wife favorite) but you have Affinity which is super and there are hundreds of YouTube videos to learn from. I'm 76 and love it. I find it much easier than PS and I don't need all of the bells and whistles that PS has. If you want something easy then just use the Develop module (sliders only). When done click on develop and then save your result. You don't need to use the Photos module. The Develop module is similar to Lightroom.

I never convert my images to the .dang format, because if you want to use non-adobe processing application, you sometimes find you can’t.

If batch processing the conversion from .dng to jpg or tif, do so in manageable chunks, say 10 at a time. Otherwise you may tie up your processor for quite a while.

Since you are on a Mac, I would look at this:

https://www.lemkesoft.de/en/products/graphicconverter/key-features

This is an incredible $40 tool, available online from Lemkesoft, or via the App Store. It converts files from around 200 formats to about 80 different formats. It will read .dng files and export them to 16-bit TIFFs.

Of course, you could also give up on the ancient, obsolete, unsupported Aperture and subscribe to the Adobe Photography Plan, which includes four applications that will read .dng files and allow you to edit them with Adobe Camera Raw... Which is what I did long ago. It was a very smart move for me.

Another option would be to get Raw Power, a raw file converter and raw file editor written by the folks who originally wrote Aperture. https://www.gentlemencoders.com/raw-power-for-macos/index.html

Raw Power costs $40 in the App Store. It supports DNG, including linear DNG files and iPhone RAW files. However, some DNGs from drones and a few unusual DNGs are not supported as is. To check to see if your DNGs will work, open them in Apple’s Preview application. If they work in Preview, then RAW Power also supports them. If they are not supported, you can use Adobe’s DNG Converter to batch-convert them to a version of DNG supported by RAW Power. For more information on performing this batch conversion, contact gentlemencoders on their support page.

You can download DNG Converter at: https://helpx.adobe.com/camera-raw/using/adobe-dng-converter.html.

The Adobe DNG converter is for RAW to DNG. Not DNG into something else ....

shieldsadvert - your friend who created these DNGs probably has the files and the tools to convert them to JPEG. Or, are you two no longer on speaking terms? It would be really sad they gave you a bunch of files you can't use without having to buy more software.

Don't give up on Affinity Photo. Just use the functions you have already learned, then over a slow weekend, experiment. It is AMAZING its power. And if you have a specific question, you can 'message me' directly via UHH, and I'll be glad to help. I'm on my computer every weekend, and in less than two weeks, my fall classes will begin. I encourage my students to send me their questions, and on the weekend too. I'll be glad to help you.

[quote=CHG_CANON]The Adobe DNG converter is for RAW to DNG. Not DNG into something else ....

The information I provided came directly from Gentlemen Coders' support website. Apparently, they know what they're saying. They wrote Aperture, then Raw Power, and have supported the Raw Power app as people found alternatives to Aperture and Lightroom.

The specific case they mention converts one type of DNG to another type of DNG, to make the first type of DNG readable by Raw Power. So they're not converting DNG to anything else.
