Q-S1 RAW dev and WB problem
Posted By ndjedinak

I established an OK workaround for the WB issue: I use the tungsten preset, and tweak the color to taste. It's not as accurate in certain light (I can't get enough Amber at times), nor as handy, but it's good enough for now.

I still have now figured out why re-developing a raw is causing a forced crop (no matter what the selected aspect ratio is). A firmware bug, perhaps? It makes in-camera raw development fairly useless, as I rarely crop my images and compose in camera... Bummer.

Q-S1 RAW dev and WB problem
Posted By ndjedinak

I usually use a white piece of paper. I also tried a gray piece of paper, which also didn't work.

My Q will WB on the same piece of paper OK. (I tried both side by side)

Interestingly, i was able to get A custom WB to work outdoors, as long as I didn't point at a highly shaded white object. I wonder if the QS1 custom WB has a smaller range than the Q, I did notice in the manual auto WB only balances from 4k to 8k; indoors you will often be in the 2500-3000 range.

For now, I'm using Tungsten preset and tweaking to taste with additional Amber. It works OK, but it's not as handy as point and set, nor as accurate.

Thanks for the response!

Q-S1 RAW dev and WB problem

Hello! I'm a longtime Q user, and just unwrapped a new Q-S1 today. As I settle in with the camera, I've noticed a few anomalies vs the original Q and I'm hoping someone here has experienced them and knows a workaround.

Firstly, I shoot raw+jpg and often re-develop Raws in the Q. This still works similarly, but I noticed whenever I develop a raw it crops the new image. I can't seem to keep the original as-shot image crop. I usually shoot 3:2, so I thought this might be an issue with the new QS1, but even swapping back to 4:3 and developing a raw to 4:3 as-shot results in the slight crop. Anyone know what's going on here?

White Balance: I often use custom WB in the Q, as my favorite color mode (reversal film) needs accurate WB. In the Q-S1, I can't get the custom WB to work, no matter what I point it at. As I've been using this same process with my Q for years, there has to be something different about the QS1; I only occasionally get the "operation could not be completed successfully" on the Q, but get this every time I try to set WB on the new model. Has anyone experienced this?

Thanks, all, for your thoughts. Still love my original Q, I've been using it quite a bit lately. Here's my Q shots to date, if you're interested in seeing the work I do with it

That's is patently not true at base ISO. I challenge you to take a shot outside in good, even light, at base ISO, with the following settings: NR low, fine sharpness +1, shadow and highlight compensation OFF, reversal film setting. Process the RAW as you wish.

Now print both: at what print size do you note a difference? Come back and report results. Try adding a WG2 in the mix, if you have one, to test your theory.

I wouldn't say reduction in IQ is barely noticeable, but I agree with your sentiment; for me, the AF speed is so much better I've stuck with the new FW and started to process RAWs when I really want detail out of an image.

Poll: Did you buy a 2nd Q?

I don't see a poll, but I'm on tapatalk.

In any case, I did buy a 2nd Q. My wife often takes the Q when she travels, and I missed having it around. I considered waiting for the Q10, but I really like the jewel-like miniature magnesium construction, and I'm happy with the IQ, so I stuck with the ur-Q.

Selar, the Q's results can look P&S-like, but only if processed like a P&S image. Try shooting with fine sharpness +1, NR low, shadow and highlight compensation OFF, and reversal film setting. Use custom WB indoors and outdoors if the light is blue. Or shoot RAW. Shot RAW, the results remind me much of my old Nikon D200, up to ISO640. That's pretty astonishing to me.

28mm showdown commences: Q vs GRD vs XPro vs DP1M

Re: the DP1M performing like the Pentax 67... It can! It will! You will be thrilled.

By all accounts the 45mm on the DP2M is the "better" of the two lenses, but surely this is apples to oranges. The 28mm on the DP1M is at least the equal of anything I've used in 28, and better than most. I have zero qualms about this lens other than flare, as it is quite flare-y and not in a pleasant way, with a green tinge common across the frame:

SDIM0111 by ndjedinak, on Flickr

You can see that also here on the right; green bokeh balls:

SDIM0224 by ndjedinak, on Flickr

But you can also get the sensor to flare in a spectacular way, as the Q:

SDIM0088_spp by ndjedinak, on Flickr

When you want edge to edge sharpness, through, this lens will deliver, and the distortion is quite low (no correction applied here):

SDIM0280 by ndjedinak, on Flickr

I have a DP2M on the way. It will go under the Christmas tree, so I won't be able to report until next year... But in the meantime, know that you can crop your 1 and still get fab quality... This was about a 38mm effective crop:

It's a great lens!

Thanks, the key is to shoot RAW and process in a converter that allows you to fine tune noise reduction. I don't mind grain so I turn luminance NR off entirely and sprinkle color reduction to taste. Don't underexpose and pull up shadows, just leave the ambiance as-is. If you shoot "stuff" you can dial in some -EV for more ambiance. For people, shoot 0EV or you'll want to pull up shadows on skin in post, and that won't go well :) That's it, really, no special magic! The Q's sensor is quite good.

Here's a silly shot of a friend at 3200.

IMGP0543_LR by ndjedinak, on Flickr

As I mentioned, my Q tends to push custom WB to the cool and magenta side. I'd like to sort that. Otherwise, impressive for a tiny sensored compact camera! To be honest, I personally couldn't do a whole lot better with film in this murderous lighting. And to think the Q fits in the palm of your hand. Astonishing! Here's a shot from years ago on Fuji 800z negative film pretty similar in nasty lighting, I think.

Yes, this is the same sensor used in the (originally) $7k DSLR. That camera is down to sub-2k. Sigma knew they had something special on their hands, as the sensor competes quite well with medium format. But, of course, the rest of their ecosystem doesn't, so the market spoke and the price came down.

Truthfully, I think the DP series is their zenith. Sigma can make very fine lenses if they want, and they have done so with the DP series from the start. It's pretty freeing to design a lens for one specific sensor that will never come off a body--see the Fuji X100 and Sony RX1 for other examples.

I have no doubt the Sigma Merrill's will out resolve the Nikon D600. They can out resolve the D800E in certain circumstances (too complex to predict for me right now, it depends upon the color of the light and other factors); one things for sure, they "compete" with the best of what FF has to offer in terms of resolution (D800E) and compete quite well with medium format. To get DP1/2 results out of a D800E you need the best Nikon glass; the Sigma already comes with the best glass, and at $1k vs $4.5k is pretty astonishing!

But, they are very narrow tools. Don't go inside with your friend as the Sigma really falls down as I've shown above. Also--the Foveon is a very different beast... It renders significantly differently from any other sensor on the market. I still shoot a fair amount of film, and its more like film than anything digital, IMO. It has a certain "feel" you will either like, or not.

If you'd like a full-resolution file to chew on, PM me your email address and I'll send one over. I promise your jaw will drop :)

I've been considering "going light" by taking only the Q on my next holiday abroad, so I took it along for an evening birthday celebration. I remain impressed with the Q; I can lean on the IS and keep the ISO down if I'd like (1/15 is a sure thing, 1/8 is almost as sure):

IMGP0538_LR by ndjedinak, on Flickr

Or I can push the shutter speed up to more easily capture live subjects... This one at ISO 3200:

IMGP0542_LR by ndjedinak, on Flickr

I'd like to figure out how to get custom WB to render more neutral, as mine seems to take on a magenta hue fairly typically. In general, though, I really can't fault this camera. It's so darn small, and so darn good.

No way will the K5IIs be the same in ultimate resolution; it won't even be close. Here's a quick comparo I ran vs the new Sony RX1 full frame monster:

RX1vsDP1MvsXPro by ndjedinak, on Flickr

I think you can take it to the bank that the Sony will have more resolution than the K5IIs, and the Sigma has more than that. Really, the Sigma is far and above anything I've ever seen out of digital--it's even better than I have personally been able to get out of MF film. That said, its really quite a lot like film, and you have to be prepared for some struggles to get that magic. Reichmann over at Luminous Landscape said the Sigma's weren't for p@ssys, and he wasn't kidding. I'll have an article written shortly about how the Sigma defeated me over the thanksgiving holiday :)

Back to the 28mm comparison... Here's Part II, with ISO 1600 and 3200 comparisons. A quick teaser: the Q bests the "large sensor" Sigma! ;)
28mm Comparison, Part II

I remain impressed and pleased by the Q. I intended to add a dog shot to the mix today, but unfortunately my "subject" moved and ruined the shot for the Sigma. I did get a close comparo of the Q vs GRD IV:

QvsGRDIV_Henry by ndjedinak, on Flickr

In retrospect, I should have set a custom WB for the GRD as I did for the Q. Notwithstanding the poor testing protocol (haha!), I find the Q to better the GRD in ultimate resolution, which is pretty impressive considering I'm using a "kit" style zoom on the Q vs the GRD's prime. The GRD isn't bad, by any stretch, and does appear to have better local contrast; but the Q just nets a little more detail, as it should for 20% more resolution (but isn't guaranteed because of the sensor size difference!).

I think Pentax made the right decision to stick with the 1/2.3" sensor size. It's clear this one is a few generations ahead of the GRD's aging CCD. And even though the GRD is optimized with a very thin AA filter, well-developed processing, and has a larger sensor, the Q is a little better, all around. Pretty impressive! The GRD does have some real strengths, though, and is a completely enjoyable camera to use. So they both win, in my book :)

You may have a bad zoom. Check it in good light--if its a good copy, it should be just about as sharp as the 01 with just a tiny bit less contrast. I have 2 copies of the zoom--one good, one mediocre :/

Absolutely, at base ISO, with respect to detail and sharpness... The sigma kicks the crap out of the Fuji. Color and lens rendering are in the eye of the beholder--I think both systems have strengths that are somewhat different.

I personally am floored by the Sigma and look forward to getting to know it.

You might consider returning it to Pentax; I would have agreed, given the performance of my first coy of the Q zoom. However, I bought a 2nd Q kit, and the second copy of the 02 is MUCH better. I have yet to contact Pentax about it, myself, but I plan to.

X-Pro is an interesting camera--it confounds and overjoys me, in equal measure. You can read more on my blog. One thing is certain--it is unique!

The Sigma doesn't struggle with WB any more than the Q, I think; I set a custom WB for the Q and its always a little too red/cool at high ISO. The Ricoh nails it more often than not! X-Pro is fairly good there, also, but the Ricoh is closest to natural.

It is certain the Sigma starts to struggle with colors at ISO 800, though. That's the limit, I think. Here's and ISO 200 shot:

SDIM0127 by ndjedinak, on Flickr

And an ISO800 shot taken a few minutes later:

SDIM0134 by ndjedinak, on Flickr

Surely, I can do better once I learn the Sigma RAW tool, but you can see it starting to falter. The Q definitely holds up better at high ISO, I'll try to post 1600 and 3200 tonight which will show that well.

I find the sigma very much like carrying 2 films: color slide film up to ISO 800 (it even behaves similarly) and B&W 1000-3200. If you think of it in that way, it works quite well.

Since I'm a confirmed 28mm hoarder, and my new Q 02 zoom has proven quite a bit better than my first copy of that lens, I started a series of 28mm showdowns. Eventually, I'll add film into the mix, as I'm really curious as to how well the Q stacks up--my feeling is pretty darn well.

The first installment is here; if anyone is interested in any particular tests, let me know and I will try to accommodate. These aren't scientific method tests--I'm nowhere near that thorough. Mostly for fun and information.

To give a quick teaser: the Q competes VERY well with the Ricoh GRD IV at base ISO and pulls ahead at ISO 800. At 800 the Q is even catching up with the DP1M; or shall I say the DP1M is faltering ;)

Huge differences in composition and "feel" between these formats; I personally prefer 3:2, followed by 1:1, then 16:9, and lastly 4:3. 4:3 and I just don't get along well, so I don't use it a lot, although I dabble a bit now and again.

I recommend shooting for a week at each to get a feel for the different "feels" so you'll know when to apply them.

Lots of fun.
