FZ300 Dark Center of Image

LumixFZ300 · Mar 21, 2016

I have noticed that all my pictures that have been converted from RAW to Dng in Adobes DNG converter, and then opened in LR5 have a strange dark area in the same central position almost like what you would get with vignetting.

I have tried the manual adjustment for that in LR but it only maked it more exaggerated one way or the other, i have the camera set to normal metering not spot or center weighted, but tend to dial in 1/3 -2/3 of - EC.

I am using the extreme 600mm end for 99% of my shots and have added a slightly longer (just by about 2inches) lens hood on the end to help with reflections, i cant imagine it being the hood because surely it would do the opposite and create dark edges not a dark center.

Just to add folks - i have checked all the pictures and they are all like it no matter if EC has been dialed in or not they show up really well with large areas of sky - its like vignetting but reveresed.

Any ideas please.

It's very difficult to guess without seeing an example or two so maybe you could post some examples for us? Maybe there's something wrong in the RAW conversion or a setting isn't right. Are you using any filters like a polarizer or neutral density filter?

Sounds like LR5 is overdoing the automatic vignetting correction. Don't know why it's happening. Not really helpful. Sorry. ;-)

Here is a couple of pics folks they are distant plane shots with a lot of sky but it does show the central darkening

Does it? It's very, very faint if it's there. Could it be your monitor? My own monitor isn't completely evenly lit across the screen.

I can see the darker area you are talking about. However I do not have an FZ300 nor do I use the programs you speak of. Just agreeing with you that something is wrong.

No dark spot here my friend. The samples are small but I made them as large as possible on my 39" screen and nothing! You might post larger size?

Warmest regards,

Its really obvious when viewed in the thumbnails each and everyone showing the exact same shadow in the center just like a center weighted shadow.

Could it be something to do with the RAW processing? i havn't tried the jpeg shooting as i allways process my files in Lightroom all though as a DNG not RAW file.

If you look at your .RW2 files with Irfanview, for example, you'll see the 1/4 resolution JPG which is embedded in the .RW2

You don't need to look at a separate .JPG.

If you look at the .RW2 files in Picasa, you'll see the .RW2 without lightroom's processing.

Alternatively, you could share the .RW2 files in Dropbox or something similar and other people on the forum can look at them directly.

I loaded the 2nd image into lightroom and measured the RGB values across the diagonal from lower left to upper right.

Values were:

Lower Left Corner: R:43.5/G:45.6/B:55.3

Centre near aircraft: R:43.0/G:45.0/B:55.1

Upper Right Corner: R:43.3/G:45.5/:55.9

The lower the values the darker the image. Not surprisingly the predominant values are the blues. So there is some darkening in the centre, but it is so little I cannot see it. I have a hardware calibrated monitor so I am reasonably certain about the accuracy of what my monitor displays even though I can't claim the same about my eyes!

I suggest you view the images on another monitor (preferrably a hardware calibrated one) and then decide if you still have a problem.

Not so much with the 1st image but can see a very gradual darkness difference in the center; but on my display can also see grain that could be due from RAW PP, and some uneven blotches throughout the sky. To increase their appearance I max out image contrast and saturation for the image below:

Below is your 2nd image I did a quick PP with PSE 14 and Topaz DeNoise to lessen lluminance noise and chroma (color) noise:

Good possibility. In troubleshooting possible camera/ sensor image issues should be looking at the OOC (out of camera) JPG's. No telling what your RAW PP is doing to the images. Also be helpful if images posted are at least 50% of the full image resolution; 1500x1002 on the small side to do a good evaluation.

Why? The ONLY time I DNG files is when I get a newer camera and the application/ ACR version I'm using do not support the camera's RAW files.

I have been looking through my first set of images that i converted in Slkypix that came with the cam, these were saved as lossless Tiffs, all these images dont seem to show the same darkening as the RAW-DNG conversions(its the current Adobe DNG convertor and i have been saving with the full Jpeg preview and lossless with no compression)

Thanks for that jon,

I have to use DNG as its the only way to process my RAW s and leave me with a non destructive way of doing the edditing i do in LR5, i can not afford to get LR6.9 for the RAW compatablity, so i dont kno what else to do -

I didnt like Silkypix that came with the cam,

Shooting in Jpeg does not gve me the None destructive edditing in LR.

OK, you're using the DNG for the same reason I noted. ;-)

How extensively do you use all the LR 5 RAW PP tools? May want to do a side-by-side of LR 5 and PSE 14. Your location not noted in your Profile, but in the USA can find PSE 14 online for around $69, if it fits your RAW PP needs.

FYI as to JPG images. I do not use LR, but you might try and find out (Google search) if there's an option to open JPG images with ACR. With PSE you can use the Menu File, "Open in Camera RAW" to open JPG image in Camera RAW, and does the same non destructive editing; i.e., as with RAW images PP changes saved to .xmp sidecar file. I always edited JPG files with PSE in this way; e.g., see my post HERE.

Jon

I cant afford to buy PSE12 etc i have not long purchased the full version of LR5.7 as i understood it would handle the DNG files from Adobe DNG 9.1 ok?

Just dont want to shoot Jpeg and suffer destructive edditing with them in LR5, i wish there was a work around to fix this.

Pretty sure that LR's "non-destructive" editing also works with JPEG images.

If the photo is shot in Jpeg then opened up in Lr5 and worked on, the original Jpeg is not saved and any changes are i believe un changable and lost for ever.

Guess we're having some kind of language barrier?

I explained in my previous reply how you could possibly processed a JPG file without ANY destructive editing. Been doing non-destructive JPG editing with PSE via the "Open in Camera RAW" for YEARS. Be surprised if LR 5.7 unable to do the same.

As a last resort you could easily COPY the original JPG images to another folder and edit the copies of the JPG images.

I understood that all alterations to a jpeg file in LR was un doable as the original file was not saved like a RAW file is - another words with a RAW file you can change it as many times as you want, but the RAW will allways stay pure and negative to go back to when ever you wanted, i understood jpegs were different?
