Problem with my D7000 - JPG show as slightly curved while RAW show straighter lines

Dear everyone,

I am having some small problems with my DSLR: lately I noticed that when I shoot photos in .JPG, the center of the photo is slightly "inflated," (please see GIF below.)

The RAW file is fine and does not present this problem; photos shown in GIF for comparison are exactly the same.

Does anyone know how can I fix this issue? It will probably be something on the camera settings.

Thank you very much,

What lens are you using? What software are you using to process the RAW file. RAW files must be processed to get the best shot.

Dear Don,

Thank you for your prompt response!

I am using a AF-S Nikkor 18-105mm.
The RAW photo shown is not processed, it is directly uploaded from the camera SD card.
I wanted to know why in the .JPG the lines are not straight...

Thank you
 
Are you planning to shoot in Jpeg or RAW? Also have you adjusted the settings for JPG in your camera. There are a number of things you can do there. Personally I only shoot RAW and I process each one of them to get the most out of every photo.
As far as I can see there is not enough difference in the two photos you show to ever see in a photo.

Right now I am shooting in both RAW and JPG. I think using JPG would be easier because this file type can be read everywhere while for RAW you would need specific computer programs to open them. I did not adjust the JPG settings, what should I change?
 
You do lose some quality in shooting JPG but shooting RAW does dictate doing more post processing. If you are going to shoot JPG then you need to set your camera properly using the following guidelines.

If you are shooting JPG I would suggest that you use the Fine>>Large setting and also set your camera for better sharpness.



Go into your Menus and highlight the "Shooting" menu (the camera icon)

Drop down to "Picture Controls" and click right one time.

From here, highlight "Standard" and then click right one time.

From this settings menu, increase the "Sharpness" setting to "7".

Drop down and increase the "Saturation" setting +1 notch on the slider.

Press "OK" to exit the menus and you're done.

What you're seeing in the RAW file is called "barrel distortion" and your camera is probably correcting it automatically when you shoot JPG. It's a pretty safe bet your camera has the Distortion Correction enabled (check your Shooting menu) and that's why you're not seeing the distortion in the JPG images.

Conversely, RAW files do not have any such corrections applied in-camera; you have to do those sorts of corrections yourself during post processing.

I went through the process of first shooting jpeg, then raw + jpeg, then just raw. It does take some time to review the raw photos and make corrections but, after experiencing how could save a lot of photos, going all raw for me has been the best option. I use the Nikon ViewNX2 software for the corrections & conversion.
