I am a professional Photographer and videographer with 13 years of experience both in studio work and ourdoor events. I had the Mavic Pro, Mavic 2 Pro and recently the Mini 4 pro. I chose this unit for the compact design and fast - on the go aerial footage. When I took some photos from my Mini 4 Pro, I was a bit disappointed with the output quality it put out. Checking on the image size and quality on software program like PS, it only showed @ 72 resolution and 4032 x 3024 pixels. That 72 reso was a big disapointment. and pixel peeping the outputs coming from the shots was crappy. I don't know if it's sensor related since the mavic 2 pro takes awesome photos since it has a 1 inch sensor. I hope there will be an improvement for this on firmware update for the mini 4 pro.

I'm by no means an expert, but it sounds like you might have the photos on their default settings.

I just had a look at the last photos I took with mine (it's set to store RAW and JPG), back in June, and the JPG image is 8064x6048 @ 96dpi. If I convert the DNG file using default settings i.e. keep properties the same, the resultant image is 8064x6048 @ 240dpi.

I suppose that a professional photographer should know that the DPI information saved in a picture file is just a metadata and it has nothing to do with the quality of the image. It can be easily changed without any impact on the picture. The only meaning of that information is for printing purposes and it makes a lot of sense for scanned documents, but not too much for the pictures.
An improper use of that information in resizing/scaling can bring to a bad output. Based on my experience, the quality  of the pictures taken by a Mini 4 cannot be compared with the ones taken by a professional equipment (it’s a consumer drone). But it’s quite good. If you’ve doubt about the quality of your pictures, I suggest to share some of them (in the original format) together with your concerns. And we can have a discussion based on facts.

72 dpi is meaningless and it's irrelevant to image resolution.

The Mini 4 pro has a tiny sensor which has a big impact on image quality.
No firmware update can do anything about that.

thank you for this. i will get back to you after for results

for my experience... untouched/ un-manipulated dpi has a lot to do with having sharper and better images.

You've shown that you aren't very experienced at all.

Most cameras display images at a default 72 dpi but this doesn't mean the image is low resolution or low quality.
It's not the image resolution at all.

It's the standard screen resolution for viewing digital images on monitors.

In my experience the quality and the sharpness of a printed image depends on the number of pixel you put on a sheet of a given size. And this has nothing to with the dpi value published in the metadata of the original image file. It’s just the result of a calculation  involving the number of pixels available in the file (dots) and the size of the sheet (inches).
Of course the drone does not know the size of your final printout. It assign an arbitrary value to the dpi. It’s up to the photographer to adjust that value, depending on the size of the sheet. If you want to print a picture from the Mini 4 Pro keeping its original 72 dpi, you need a sheet of 56 inches ...
And I’m really surprised that an experienced professional photographer needs this kind of explanations …

I'm not using this for printing. it's all about the uav's photo output quality. and your explanation is not needed  i have lost interest on this post and will be selling my unit.

It's such a shame that so many people don't understand what DPI means.

I'll try to explain it:
A sensor has a certain resolution, e.g. 8064x6048 pixels.
Anyone who wants to calculate the resolution of the sensor is welcome to do so, because these pixels are arranged on the 1/1.3-inch CMOS sensor.

If the image is saved as a file, a DPI (Dots per inch) value is stored in the metadata (EXIF). However, this is just a value and has nothing to do with the pixels that the sensor recorded.

I only need a DPI value when I want to print or develop the image. Let's assume we want to use a good print quality of 300 dpi (E.g. on photo paper
), this means that the printer prints 300 pixels on 1 inch. The image has 8064x6048 pixels, so at a resolution of 300 dpi it will be 26.88 x 20.16 inches (68.3 x 51.2 cm).

Canvas with stretcher frames are printed at 120 dpi, which means that the same image will be printed 171 x 128 cm.



Computer monitors usually have a resolution of 96 dpi. As a result, the monitor would have to be 213 x 160 cm in size if we wanted to display the image at 100%. Since our monitors are smaller, we have to scroll :-)

I hope this has all become a little clearer now.

Many people may be not aware of those technical details that in most cases are not relevat. The real shame here is that a person that presented hisself as a professional photographer started telling that the quality of M4P pictures is bad just because it saves at only 72 dpi …

You can simply change the DPI to whatever number you want in PS.  As others have stated, this will not affect the quality or resolution of the photo.

It's such a shame that this professional photographer and videographer didn't try changing the settings as I suggested, but has instead decided to sell the drone. I wonder if they will complain about the quality of the image from their next purchase.

I`m a full time Pro photographer too and Just grabbed a Mini 3 "Standard" on clearance which has the same camera as the Mini 4 Pro and I`m knocked out with the stills quality in JPG even and especially RAW - the sensor maybe a bit smaller than 1" (it`s about 3/4") but when I tried an ISO100 48Mp RAW shot , developed it in Photoshop with Enhance details and downsized to 20Mp, it pixel peeps as good as anything from a RAW shot Sony RX100 or RX10 series (Premium 1" sensor cameras), I`m sure that the 1 inch cams would pull ahead at higher ISOs but keep it sensible and the 1:1.3 does nice  .. 12Mp is superb at ISO100 , far better than the mush my Iphone 11 puts out ..... this was on my first flight with the drone (I have had a Mini 1 and a Phantom 3 Pro previously and do have a Neo as well) ..
As everyone has said . DPI is just a tag in the EXIF Data, it`s the amount of pixels (IE 4000x3000) which counts..
