I'm not trying to prove anything; just doing something different to how have done it for quite a few years

AND YES; there is a big difference; but how many are going to make an enlargement that big as those crops represent. from memory it's around 3:1/4:1 crop.

Re: raw v jpeg experiment.

But those big crops are more beneficial for getting the effect of a 2000mm lens but printed at A4 or smaller. A good way of avoiding GAS

Re: raw v jpeg experiment.

Picasa3 turns the RAW file into these jpgs

Re: raw v jpeg experiment.

Had time to play over the weekend...

This is a jpg straight from the camera:


These are crops from three different source files:
Left straight from Camera (as above)
Middle an OV3 jpg from RAW
Right the embedded jpg from the RAW file (essentially what you see on the rear screen)



The jpg from OV3 is about twice the file size of the one straight from the camera.

Re: raw v jpeg experiment.

When someone refers to the "default" settings applied by processing RAW to JPEG in OV3, does this mean processing with all the settings that were specified in the camera, stored in the RAW image, and used by OV3; or does it mean looking at each setting in the OV3 RAW edit pane and setting it to 0/normal/none or whatever is appropriate and disregarding the camera setting?

I would hope that in camera processing and OV3 processing (using the settings saved in the RAW file) would produce identical results but I am not sure if the file compression is identical as the options do not have the same name and this may affect the final jpeg slightly and hence subsequent viewing. Is the first post trying to show that two such jpegs are not as close as I would like?

That is a very good question:

As I have all the camera settings to "Factory Default", except WB that is set to 6300K for me I then process the RAW file to what I want. On this ocasion for "comparison" I set all the OV3 settings to ZERO with WB "As Shot"

I have concluded that the in camera jpg is significantly different to the OV3 produced jpg as file size is almost double from OV3 and as shown the Triptych there is a visible difference.

Re: raw v jpeg experiment.

Olympus Viewer generally duplicates all the camera image quality options but also adds more adjustment flexibility.

OV does indeed recognise all the camera settings which are saved with the photo (RAW and JOEG) and so the 'default' settings will be determined by the camera.

This only applies to Olympus cameras though.

Lightroom can recognise basic camera settings like shutter speed and aperture, but it won't know the noise filter setting or precise white balance or any effects modes, etc., which OV will.

Re: raw v jpeg experiment.

Well this is a strange thread,
started with some Jpegs which cannot demonstrate at all the advantages of RAW processing.
There are even hints that some people think a default Jpeg from RAW through any processor is an image of the RAW file ... but there is no such thing as a visible RAW.

What does appear useful is identification of which processors are likely to cock up a photo and give orange faces or more noise or underexposure, so need to be watched for that.

We could do with some other "editors" examples to see what they do ti Ian's file.

Anyone got a version of Capture One that will open the ORF raw file

Re: raw v jpeg experiment.

Processed from ORF with CyberLink PhotoDirector 4 into JPEG (and the jpeg then resized, cropped, and saved in low quality on OV3 for upload to the forum).

Re: raw v jpeg experiment.

After long hesitation, I have had a go at processing the image. The size seems limited by the site album system

Re: raw v jpeg experiment.

Capture One 8


The question is why pick this guy for a 100% crop as he is the least sharp and possibly out of focus person in the image.

where as this guy is in focus and fairly sharp.
