Pentax Full Frame
Here's a question for those moist over a Pentax FF .... How will a FF camera improve the standard of your photography over what you can get from a K-5 or K30? LOL, deserves it's own thread rather than being stuck in another lame 'Pentax FF COMING SOON!!' one. Seriously APS-C sized sensors will...

Pentax Full Frame
If you see any Leicas in the sales for 1/6th of their usual price let me know :mrgreen: The f/1.2 on ebay is the same as one I've got. It's quite a good lens and is a K mount. I've also got the M42 Chinon Tomioka (labeled) one and the Pentax K 50mm f/1.2. The one similar to the ebay one is ...

Pentax Full Frame
Can't wait for the Pentax FF to hit the market, but was surprised to what extent Bill Gekas manages to make the K-5 look like an FF camera. Have a look at his image. I love the smooth tonality transitions. If you want to fully appreciate it, download , scoot to page 86, and watch it full ...

Pentax Full Frame
In the early 1960s the two top professional systems were...Nikon and Pentax. Pentax produced some very special professional and scientific products, such as the Nocta night vision kit for surveillance and the UV Takumar lenses for scientific use, recording oscilloscopes for one. Pentax Takumar...

Pentax Full Frame
Don't forget Pentax also produced the LX back in the 80's - a professional specification camera system of the highest order - I knew several Canon and Nikon users who were genuinely impressed, but they stuck to their own brands because of the "buy-in" to those systems... ...a bit like some of us ...

Here's a question for those moist over a Pentax FF
I was looking at an old film SLR my son was using last week. I was very struck by how near the back the film plane mark was compared to on my K5. No wonder the film camera was slimmer, As to formats our own vision is wider than it is tall so no surprise at rectangular being the choice. If Pent...

Here's a question for those moist over a Pentax FF
If I were photographing say wedding groups I wouldn't want extra DOF which could mean some people were OOF so APS-C would be preferable. - I need to try that controversial technique. I do make the assumption that "extra" means more and "OOF" is Out Of Focus. "Smeggypants wrote: ... How will...

If we all want better IQ. colour rendering and sharpness we should go back to using FILM now that would be progress.:shock::wink::D Cheers Dave

Sharpening in Photoshop
Carrying on from a point in another thread, a discussion of sharpening. As little as needed avoids haloes and other artifacts, and Unsharp Mask is my tool of choice. I have used this from Photoshop 7 through to CS5, which I currently use. Unsharp Mask, Threshold 3, Radius and amount depending ...

Sharpening in Photoshop
In lightroom if using the sharpening module press the 'ALT' key in windows or mac key on mac and the image turns black and white and shows exactly what is being sharpened. If you then choose the mask slide and again click and hold teh 'ALT' key as you slide less becomes sharpened until just the i...

Sharpening in Photoshop
The technique of converting to LAB mode and just sharpening the luminance (black and white) channel is useful for architectural subjects as the colour information is not affected at all, so we end up with an underlying very sharp image with no artefacts in the colour channels. We convert back to RGB...

Sharpening in Photoshop
Going to put the camera back to default and forget about the magic of manipultion, to much grey matter overload. Photoshops heading for the recycle bin. Cheeeeeeeeeeeeeerssss Dave the nearly raving looooony:roll::roll::roll:

Sharpening in Photoshop
It's interesting the different approaches people have. For web sized images I typically choose a small radius (0.2 or 0.3) and a large amount, to sharpen fine details without creating large haloes. I also use Focus Magic plug-in sometimes, more for 'corrective sharpening' rather than fine tuning a r...

Sharpening in Photoshop
Continuing from another discussion, I prefer using Unsharp Mask for sharpening. I've used it in Photoshop versions 7 through CS5. For web images (around 1000 pixels on the longest side), I use Threshold 3, with a radius of 1.1 to 1.4 pixels and an amount of 50% for some cameras like K20D or K-5, and...

Pentax Q + PK adaptor + 50mm f2 DOF?
It's still interesting ;) I've got the 50/1.4 on the adapter - and the DOF is still very shallow with lovely bokeh! Manual focus is extremely sensitive at f/1.4 though! The focus peaking helps, but you need a tripod really ;) Matt

To Clone, or not to Clone...
... that is the question. I shoot landscapes, and I've recently been uploading a few shots for the first time to the gallery, and cloning has come up a couple of times in comments and suggestions. Both times, the suggestions were bang on (thank you bwlchmawr and Hullman), and cloning out the su...

To Clone, or not to Clone...
IMO we live in world where media is far too false already. Pretty much every celebrity photograph has been cloned and warped ( often with hilarious and anatomically impossible results ) Many news images are fraudulent in that they are set up. Even the Raising the Flag on Iwo Jima was staged. Eve...

To Clone, or not to Clone...
We all should probably think about this and set some personal 'standards' for our 'private' photography. Its a different ball-game if you're putting your shots up in the public domain where they will be judged on some external criteria - competitions rules, or if they are news-related then the fidel...
