Hi Chaps... and a very merry xmas to you all...

I've recently started to sort out a few descent images to put onto my nas to show the family.... but I just have a rather odd question to ask.

I shoot with two cameras, one is a (I don't care if it falls on the floor camera) a Fuji Finepix, s4000,... I'm not to bothered about it, as I't came from a mate who was upgrading and it also suffers from the usual fuji full single line of dead pixels. But the output is 4288x2416 which is a totally perfect fit for a 1080p widescreen tv...

But my KX seems to only output at 4288x2848 with these horrid black bars either side.... Is there something that I'm missing or is the the norm for the KX?
I just wanted the very best res from my kx and hopefully to fill the screen without having to start hacking the images with photoshop.

Appreciate any pointers chaps....

Attached 2 images to show what i mean,... i've shrunk these due to size in mb.

gull is on fuji, and coastal is on kx.

The K-x captures photos in a 3:2 aspect ratio. You'd have to crop them in post to a 16:9 aspect ratio if you don't want black bars.

DSLRs typically don't allow you to change the aspect ratio in-camera, unlike compact cameras.

Thanks Adam,

I've just been having a quick look at the Kr,.... would I be correct in stating that the Kr does have a resolution of 4288x2416?

If it does, it's a pity, because there's not much chance of my getting hold of a new one now....

APS-C sensors are 3:2 ratio. You will need to crop in post to get 16:9 suitable for 1080p TV screens.

Not sure where you got the above specs from, but K-r resolutions are:
• [12M] 4288 x 2848 pixels
• [10M] 3936 x 2624 pixels
• [6M] 3072 x 2048 pixels
• [2M] 1728 x 1152 pixels

It's got the same resolution as the K-x, yes.

Forgive me if you already know this, but your Fuji is just 'hacking' off a bit from the top and a bit from the bottom in-camera to fit the 16:9 ratio, exactly what you would do in photoshop or any other editing program. Having this setting built in to the camera may be more convenient if you're set on this output ratio, but you aren't gaining any image quality by having this as an option.

I found another version on an italian ricoh site:

Confronto prodotti - PENTAX Photo

Fotografie Qualità: FINE, NORMAL, RAW (DNG) *2
16:9 (4288x2416, 3456x1944)
4:3(3776x2832,3072x2304,2592×1944, 2048×1536, 1280×960, 640×480)
3:2 (4288x2848, 3456x2304)
1:1 (2848x2848, 2304x2304)

I'm just wondering if Pentax do a dslr that has 4288x2416 as a selectable standard.... as a possible upgrade to my kx.... something just like my me super, with a perfect b setting, and a screwable trigger. and a descent battery grip..
where did Pentax go wrong.... lol

cheers for the help chaps..

You've got the wrong model selected there, they are the settings for the GXR, not the Pentax K-r
Select Pentax K-r and once again you'll see:
JPEG: [12M] 4288x2428 pixel, [10M] 3936x2624 pixel, [6M] 3072x2048 pixel, [2M] 1728x1152 pixel
3 livelli di qualità in JPEG (buono, migliore, ottimo)
RAW: [12M] 4288x2428 pixel.

If you want a grip you will need to grab a K-7 or K-5 (can be bought quite cheap on eBay or PF classifieds)

[Giklab]

Pretty sure the K-01 does multiple aspect ratios.

[WildBikerBill]

The K-01 does do multiple aspect ratios, specifically: 16:9, 3:2, 4:3, and 1:1
I have mine on my desk next to me and just dove into its menus to check.

The K-01 is the same generation as the K-30 / K-50 cameras, so they probably do as well.

it really looks as though you'll have to crop/resize you kx images to display the way you want
there is not an in camera setting for 16:9

in a couple of the pgms I use I just set a new document to 1920x1280 @300 ppi
paste the original image as a new layer
juggle it around to get what I want
flatten the layers
save it (in your case to the NAS) and display

In another I just crop/resize to 16:9 @300ppi and save it

at that resolution I haven't had any trouble with displaying the images on very large televisions

in theory using a 16:9 ratio in camera loses some pixels from the start
I tend to shoot most things at the native resolution with the intention of cropping later
it just suits my workflow as I can make the image suit whatever use I need downstream

hope that helps a little

[mee]

Just set up a batch job to convert them to 16:9 on your PC and be done with it.

All the fuji camera is doing is this same thing on the fly. It is just cutting your image (cropping) by removing some of the top and bottom of the actual image and discarding it. Wouldn't you rather have more data available to you for other pursuits (such as printing) ?

So I'd just let the camera shoot in its native 3:2 (as they all do, even the FUJI) and batch convert for showing on the tele.

[ccc_]

that is the quickest method but there is no control over what part of the image is removed
