JPEG Image Size

A few recent threads at www.Pentaxforums.com [1], [2], [3] triggered my interest to generate this poll:
[1] https://www.pentaxforums.com/forums/pentax-beginners-corner-q/96629-image-size.html
[2] PPL: JPEG quality vs compression vs size - PentaxForums.com
[3] JPEG file size - PentaxForums.com

For thus of us who shoot JPEGs, what is your preferred/favorite number of recorded pixels (a) and JPEG quality level setting (b) ?
(a) 14 Mp, 10 Mp, 6 Mp, 2 Mp
(b) [***], [***], [**], (*]

I typically shoot JPEG files with 6Mp [***]. And you ?

I thank you all in advance for your input.

Well most of the Pentax cameras that I've had were only 6 megapixels, but I never used JPEG, I always used RAW with them.

Sorry for that and you are right. I should have proposed 12/14 Mp in the same category.

Suggest that K-x users tick 14Mp for 12/14 Mp.

Use biggest possible just in case. You can always reduce its size later.

Hi hcc,

I'm a jpeg shooter, and normally shoot 14MP ***. I tried **** on both the K20 and K-7, used PP to try accentuate any differences and found nothing that would justify the larger files for my use. I also found it interesting that Pentax chose *** as the default, and had this compression ratio as its highest quality for previous models. The higher compression ratios started showing visible artifacts, so I won't use them.

My guess is that this is a marketing thing -- so many people seem to be overly impressed by the theoretical "more has got to be better".

This season, I'm going to try 6MP *** for BIF to coax a bit more speed from the body. I'll continue to shoot 14 MP *** for most situations, as I like the extra resolution for cropping leeway and the way it reacts to the PP tools I use.

Most pixels and lowest compression. Particularly important if you want to ever want to push PP more.

Only 6mp as it is enough for my needs and it doesn't take too much HD space.
I only have a laptop and don't have an external HD on it..plus with the 6mp it crams more photos in an SD card.

Also means there is more photos to lose when it fails.

I am not sure if that equates to more speed from the camera body unless you are including write speed also.

I would have thought that all photos are captured in native format (RAW) first. If that assumption is true, a sinlge RAW photo should generally beat a single JPEG photo in overall speed from the camera body in most cases because of the overhead involved in compressing the RAW into JPEG.

I use maximum resolution JPEGs and maximum image quality.

You may wonder why when on the K7 the maximum resolution and quality JPEG is typically more than 1/2 the size of a raw file.

The reason is that I may want to print big, so quality is a bit of an issue, but that I also don't PP that much. I have beed accused of pre post processing by suing JPRG settings in advance to determine how my pictures appear. I am constantly adjusting specifically contrast and saturation as the lighting dictates. (just like carrying 2 film cameras so I have different films in each to account for lighting

as for the poll, I selected only the top one (as it represents my K7) obviously I can't do this with the K10D oir *istD but the loigic above applies maximum resolution maximum quality regardless of the native resolution of the sensor

SD cards are cheap.
I'm going for the best quality = RAW!

Seeing as I have K200d, 10mp is the best I can do. I always shoot in the highest resolution possible. I paid good money for the camera. It doesn't make sense to hamstring what it can do.

However, i shoot 99% in Raw. I only shoot JPG rarely.
