I am Mac based these days (although I still have a windows PC laptop). I use MacBook with a Photoshop monthly subscription for most of my editing but I also use an iPad for quick stuff (like your image) with a free programme called Affinity Photo.

In many ways it’s the equal of Photoshop for basic editing but the menus and commands take some getting use to…when you have been weaned and brought up on PHShp. It’s a bit like going to Sony camera menus after years using Nikons. 

Yes your photo was about 0.8stop over exposed (according to Affinity) but that’s nothing for modern software to resolve.  

What’s important is understanding why its overexposed…and checking if the camera has a recurring exposure issue.

You will recall your early posted photos were set at -0.7 exp compensation. If you didn’t reset the camera when you purchased it and didn’t make that adjustment yourself, it MIGHT be the previous owner found the camera overexposed and set the exp compensation rather than having it checked out?

But there’s also the more obvious reason…a lot of dominant backlit foliage around the kite. It maybe that simply the metering system adjusted exposure for the ”majority”. The classic scenario of light subject/dark background….where you need to tell it to concentrate more on the subject.

Yes you can make the adjustments in exposure compensation but the other option is to change metering mode from the normal Mattrix (that you are using) to maybe Centre weighted or even (given the size of the bird in the frame) Spot metering. This just tells the camera to stop considering and averaging everything in the frame and consider a central area or spot area only ….to better meter/expose the subject.

Appologies if I am running on about something you already know…it’s difficult to gauge/moderate advice remotely.

I can’t recall if NX has Levels (basic exposure adjuster) control? That’s all I effectively did with your Kite so it might have been possible in NX. It’s amazing how much sharper images will look by just getting the histogram right first!


I believe there are 4 golden rules (someone else will tell me if there’s more lol) to processing your captures.

1) Shoot in uncompressed Raw file format rather than JPEG. This way you capture everything as shot without the camera interfering in what is effectively in old money ….the “film development”

2) Adjust exposure first….Sharpening last (ie only sharpen once you have finished all your other refinements.

3) Save finished master files as uncompressed files NOT jpeg.  By all means make a jpeg copy for distribution or display.

4) NEVER open a saved jpeg…work on it some more …and resave it as a jpeg again.
Each time you save as a jpeg, the algorithm “throws away” similar tones/colours to compress the file (even on best setting, some is lost). If you open up a jpeg thats already been “pruned”, when you resave it again the algorithm looks for more ”pruning”….and you gradually lose dynamic range. Just opening and resaving without even working on the file, will still systematically degrade an image!  


Thx about my image….it wasn’t so beaut with a slice of pink luncheon meat drawing the eye.:lol:

NX studio only works with RAW images as I have learned. I have 2 cards, one for RAW and the other for the jpg files. I did select RAW as the default so I could edit the images - the files are massive!

Exposure: on previous advice from yourself, I have been careful to keep an eye on the ISO settings, and any exposure compensation has been kept to zero. The shot was taken just after noon,and as the verandah faces just west of south, the sun was pretty much overhead. I looked at the file data and spot metering was selected. ISO was at 640 so that probably explains the overexposure. Aperture f8, shutter 1/250. What I do remember is that I did not have the lens hood on, although I did have a UV filter fitted.(for what it's worth).

I intended to play around with the image in NX Studio, but I was sucked into finding why the Transfer 2 program insists in locating the files from the camera in Onedrive. Good ol' Windows - what a p.i.t.a.- I delete Onedrive , and Windows updates reinstalls the blighter!! I think I have sorted it any way.

I still have the .NEF files - I export the images as jpg anyway - which is why you found the resolution low - I think.

I play with the images in the .NEF format- most of the tools aren't available for jpg images.

I'm looking forward to receiving my Kenko  x1.4 converter:-)
