Jpegs v Raw

There is a thread on DPR about this at the moment....................

This is my take on things:

Since getting my rather wonderful Pen F at the end of December I have moved more into 'mono mode'.

When I am in 'mono mode' I set my Pen F to Mono Profile 2 with a reasonable amount of vignetting but no noise. Maybe a tweak of the tone curve as well. Shooting in Jpeg I have a really good idea of what the image will end up like. Combining this with Raw capture, I can (if I want) use the higher quality output to reproduce or better what I saw at time of capture to achieve the desired result, in mono or colour.

Yes it involves more PP but I like doing this. Besides, shooting in SF jpeg mode means that if I am happy with that, there is less need for interrogating the Raw file.


I find this a great way of working.....................but it is clearly not for everyone.

Re: Jpeps v Raw

Hi Dave,

I have always shot in JPeg + RAW mode, and if I am happy with the JPeg then I don't look at the RAW file. I do some minor tweaks to the JPeg if needed.

I find it saves me a lot of time.

Dave

Lightbulb Re: Jpegs v Raw

I regularly give presentations at Clubs and this topic always comes up, so I perform the following demonstration of why RAW images are better for post processing than jpgs.

I created all these files in Photoshop, so no cameras were harmed in the process


Consider This:

I create a 16 bit file, add a gradient, then adjust the levels to make the whole image an overall "grey"

1st a 16bit (RAW) file



Using AUTO Levels you get back to approximately the original graduated grey



I then do the exact same process with an 8 Bit image

2nd an 8bit (jpg) file



Again - Using AUTO Levels you get:



I'm using "gross" manipulations of the level controls in the demonstration, but the effect is demonstrably the same with less movement of the sliders...

It's why, when I see "blocking & banding" in the sky of peoples images, I comment on the need to consider using RAW files if they are going to post process the images.
