Hi Res

Just did a hi res shot of my garden and an ordinary shot of the same. When I look at them in LR, there doesn't seem to be any difference. I cropped them both quite a lot to see if there was a difference but cannot see it.
What should I see, better detail?

Here is a crop, about 1/3rd of the image, Hi res jpg



And here is the same but an ordinary res shot from an off file, about the same crop.


Both on tripod, cropped in LR and then the auto button. Focussed on the far corner of the chair furthest away, 1/250 f 5. Em1 mk 2 12-40mm Pro lens

Re: Hi Res

Did the High Res actually work? Have you compared the file sizes?

Re: Hi Res

You need to do a 100% crop. The difference should be easy to see.
Did you have the camera really stable - an ordinary tripod may not be good enough. Try resting it on a flat concrete slab.

Re: Hi Res

As an aside, what the hell is 100% crop? Sounds like there's be nothing left.

Re: Hi Res

When you do the HiRes shot it also keeps one of the standard frames from the 8 it uses. Perhaps you have inadvertently used that one. You can tell which is the real HiRes file by simply looking at the file size.

Have you pinched my garden table and chairs. ?

Yes, really good solid tripod, plus high shutter speed 1/250th.

21mb is very small. If you look at the EXIF whats the pixel dimensions.
It should be much larger.

Just tried it.
I have my image quality set to 50MF+RAW. on shooting menu 1
3 files are created.
Assume you are shooting in RAW.

the .ORF file is the high res. shot its 10368 x 7776 pixels
the .JPG its 8160 x 6120. pixels
the. .ORI its actually a standard ORF RAW file but from one frame and is 5184 x 3888 pixels

It could be you have a different image quality setting see shooting menu 1 third item down.

It is a crop of a small enough area so that when it is displayed on the forum there will be one pixel on the monitor for every pixel in the photo.

I'm not sure about this forum but I'm guessing that if you take an 800 pixel wide crop you will be OK. Obviously you must not resize to get down to 800px.




The hires ORF file should be about 61MB.

Re: Hi Res

Thanks guys. I have managed to get the setting correct and getting big 61MB off file, will post later. But I cannot use an aperture smaller than f8, is that norman? Manual doesn't mention that.

Re: Hi Res

Here is an ordinary jpg.


This is a Hi res JPG


Shot on a sturdy tripod and head, 2 second delay, cable release.
Both done in LR, cropped to as close to 800pixel wide, then I hit the auto button. Not sure if it is a fair comparison, should the detail be the same size in each?

The ordinary JPG looks good enough for me, maybe it is my eyes but I expected more definition on the Hi res shot.
