The RAW is now uploading. I think where I am coming from is also to do with the simple mobile phone image, taken at the same time. I know it is JPG and also has been processed by the phone but I feel the camera almost did not cope as well

Tony,

Thanks for publishing that. As I said the "my edit" was not an edit, it was a blunt play with exposure to show the level of detail I had expecting in the white (but not the brightness) It looks like I have to play more with the correction within my editing software to get it right. As i mentioned above, just surprised at how my phone processed it better.

The second shots are deliberately darker to show where I think the white exposure should be so yes the rest will be dark.

I just have a domestic grade pc so the monitor is not calibrated.

I will post a link to the rates once they upload, my internet bandwidth is low

I am shooting in RAW and using Corel Aftershot pro.

I think bschriver11 is probably on the right path as they are blown out and I am using full matrix metering in the belief that it was the best for getting all round exposure, but perhaps my common usage is too challenging for it.

In each of these the RAW is the first (but changed to JPG with no correction in order to make the size manageable, I know its not accurate but it shows the effect I see in the raw)
The second is where I would have liked the detail in the whites to have been.

Perhaps I am expecting too much from the camera and will have to cover in post processing

Thinking about your point of Exposure. Quite a lot of my pictures are of boats, which tend to be large areas of white (single boat) or lots of boats (lots of white across the picture). Or in areas where boats are found (sun, water, bright subjects)

Has anyone had their K-70 seemingly constantly over-expose by a stop? Or is there a deeply hidden setting that is causing this? (+/- exposure dial is in neutral position)

I have never had a wide angle in my collection but I decided to splash out on the Pentax DA 10-17mm and then went out today for a first try.

Very pleased with the initial results and cannot believe I have not "gone wide" in the past.

I have tried a couple of times to capture fireworks with mixed results.

By their nature, displays tend to be quite short and fiddling around with the camera takes up to much time

What settings would be a good starting point?

Thanks, I wondered if there was something more technical than "We did something", "We did something more", "We did a lot", "We went too far".

Anyway, the real answer was to take some test shots.

(Re-edited following questions below)

In the main settings menu I have

HDR auto
HDR Type 1
HDR Type 2
HDR Type 3
HDR off.

I cannot find an explanation of what the differences are between the auto, type 1,type 2 and type 3 settings are, does anyone know?

I am using Corel Aftershot Pro 3.

It happily corrects it, was just surprised by the initial visual

Thanks to all who replied

I thought RAW meant RAW, a straight read of the sensor itself.

However I haw two pictures created in RAW+ mode (i.e. a JPG and a DNG)

So the JPG shows a distinct red cast, probably fooled by the large volume of red in the picture combined with the SCN "Blue Sky" setting.

I would have expected the RAW to have no such tinge but, despite being better, still has a cast. Is it simply the sensor being overwhelmed?
