    DxO and A900 self-interest thread

    With all the enthusiasm of the true convert , after all of two days with the programme, I am becoming something of a DxO Optics Pro Elite enthusiast.

    The noise reduction is the best I have seen of any converter, which I now understand to be becasue it applies NR before de-mosaicing based on the noise charactereistics of the camera sensor. See the embedded video here which explains what I am seeing in practice.

    However, the purpose of this message is to encourage anyone with an A900 to get DxO llabs to add support to yet more A900 and lens combinations. In particular, I personally would like to see Sigma 12-24mm f/4.5-5.6 EX DG support added and would hope others (Jono?) to follow suit.

    Here is the page on their website where requests for lenses can be added.

    Link to Request Page for new DxO lens combos

    My guess is the more requests they receive for any A900 +lens combination, the higher prioroty the A900 will generally receive.

    Re: DxO and A900 self-interest thread

    Hi Quentin,

    I am using C1 and have tried DxO (they've just added the CZ 16-35 to their list of supported lenses which is a good thing). However I am still holding off from getting DxO for the following reasons.

    1. I've "developped" some pictures simultaneously in C1 and in DxO starting from the same raw file and found the colors of DxO off (that is a personal thing of course). Do you have a similar experience of different colors or is it something I did wrong?

    2. I find DxO very slow, especially creating tiff files from developped raw files is imho ridiculously slow. Have you tried that?

    3. The fact that you always have to zoom to at least 75% to see various changes to me too is annoying.

    I really wanted to like this software because it has a nice workflow and lots of goodies, especially the specific lenscorrections. Now if only C1 would incorporate that in their software.

    I might still get DxO though. Like to hear your take on the points above.

    Cheers, Bob.

    Re: DxO and A900 self-interest thread

    Hi Bob,

    1. Colours seem to be OK to me, but then again I am happy to tweak them in Photoshop.

    2. It is a tad slow, even on my new i7 Vista 64 bit machine. Its a little slower than SilkyPix used to be but not by much. I can live with it.

    3. Agreed, but the lack of an image browser is more annoying to me.

    I guess the positives outweigh the negatives for me. But they do seem to be improving it and it's already just so good when it works that I would prefer to live with the limitations and get the low noise and sharp corrected images it can generate.

    Cheers

    Re: DxO and A900 self-interest thread

    Thanks for the heads-up Quentin.

    Just tried DxO on my Mac, it has wonderful lens distortion correction - love the auto de-vignette and the CA and purple fringe removal is also ace. Tried a few high ISO shots from the A700 and it was pretty good on the auto setting. Have not taken anything at high ISO on the A900 yet to try out.

    I am not sure how I would work this in to my workflow which is basically Aperture, if they had an import into Aperture plug-in then it would be useable.

    It is very slow to process, I guess there will always be a trade-off between quality and speed, but it is frustratingly slow at present. If they improve the speed by a couple of orders of magnitude and integrate it into Aperture I would go for it.

    A bit too expensive for the elite version if I was only going to use it on a few important images. I can't see me using it for every image due to the time overhead it entails.

    I'm pleased that they give a fully working demo, it is essential to be able to evaluate these programs on your own hardware.

    Hi David,

    Yes, it is a bit pricey, and you need the Elite version to get A900 support.

    But it is good.

    Yes I know Quentin, so do I.

    I am still evaluating it and I must say the results are superb. I am going back through some wide angle shots taken with the Sony 11-18mm on my old A700.
    Although I could correct some distortion with PTLens, this is another thing altogether - especially the Volume Anamorphosis tool, where you can turn spheres spherical at the edge of the frame where they had become stretched by the lens. I can see me getting this in the future.

    Re: DxO and A900 self-interest thread

    I tried DxO years ago when it first came to the market and kept updating through any number of versions.

    It does some things (like distortion corrections) really well.

    My biggest gripe, (and I think it still continues) is waiting for them to add lenses to their repertoire. A raw converter that doesn't have appropriate lens support is virtually useless.

    I am a fan of C1 and really a fan of Raw Developer (which of course is only available for us MAC folks) so I won't be buying a copy of DxO any time soon.

    Just my humble opinion

    Re: DxO and A900 self-interest thread

    In the video (see link in first post) DxO said they had added a new lab to speed up the adding of new modules. They seem to have added quite a few to the A900 already.

    I haven't tried the Anamorphosis tool yet, but it looks cool, David. I can see it would be brilliant with the Sigma 12-24mm (please go vote for it!).

    Not everyone "gets" the point of DxO Optics Pro, but now I have it, I can't imagine using any other converter.

    Re: DxO and A900 self-interest thread

    I suspect that there is little hope for them supporting the multitude of third party lenses, my Tamron 17-35 being one, but hopefully the Sigma 12-24 would be popular enough.
    I did have a Sigma 12-24 a few years ago, but felt the copy I had was poor and I sold it, perhaps a mistake.

    I can see I will need to upgrade to the CZ 16-35 sometime if I want DxO support - where does this end?

    But I'm still betting Sony will eventually do it, if it is serious in competing with Canikon.

    Re: DxO and A900 self-interest thread

    Hi Quentin,

    I got DxO as a possible alternative to use versus C1, which I still prefer, but now I am giving DxO a serious run and I found some problems with the crop tool which maybe you could resolve.
    1. Manual says a black dotted rectangle is created: not true, it is a white full line with handles. Is this it?
    2. Manual says clicking outside the rectangle will make it disappear: not true, I can click all I like it will not go away.
    3. How do you enlarge the crop to the full size of the viewer once you are committed?

    Thanks, and cheers, Bob.

    I'm on a PC and for the time being still using IDC3. I am actually convinced since I started digital that the manufacturers know their cameras best and even though their software might not be the most practical, but at least you get perfect colors at the standard settings. I have been spoiled by Canon's DPP that developed into an amazing program, and while Sony's IDC is still far from there, I have no doubt that they will eventually get it right especially that they are serious in competing on the Dslr market.

    What setting do you use on your A900 because the way I understand it is IDC3 reads those in with the raw file true?

    2. clicking outside (with the crop too still selected) works fine for me

    Yes, exactly. I personally use the creative styles extensively as I have found files need no to very little tweaking after I select the right style. My favourites are standard, landscape and vivid. Whatever you do, make sure you turn off noise reduction for each file individually. The default setting is auto, which is equivalent to NR off in the camera (which still does some NR even on this setting).

    Do I turn NR off on the camera or in the Sony software? When you select a creative stye on the camera does it automatically turn on NR?

    No, on the camera it is a separate setting, but in IDC you'll have to do it every time you switch creative styles.

    What do the DxO Optics Correction Modules actually do? I have the CZ16-35mm and I finally broke down and got the CZ24-70 used on ebay today for 1395.00 plus I got 8% cash back from live.com Both of theses lenses are listed now at Dx0

    Hi,

    They remove lens defects: CA, vignetting, and correct for distortion.

    Re: DxO and A900 self-interest thread

    Edward, the problem with using IDC and the camera's creative styles is that you're not getting an accurate histogram representation of the RAW data, and you're more than likely underexposing more than you realize. If you have zero issues with the camera's noise handling, then this is a non-issue, I guess. However, if you have qualms with the A900's noise, it's essential to set the camera's jpegs settings to achieve the closest histogram to RAW that the camera can muster, and leave it there. This will reduce the noise quite a bit. When using IDC in your workflow, you're taking a shot underexposed, then the camera jpeg engine boosts the histogram with all of it's "special sauces" like contrast, saturation, etc. When you open the RAWs in IDC, it also applies the same "special sauces," leading you to believe that you were exposed properly all along, when, in actuality, your shot was underexposed, and both the camera jpeg engine and IDC boosted the shot, causing the histogram to look correct. This gaining up of the underexposed shot adds lots of noise.

    Does all of this babbling make any sense?

    Hi There
    such interesting information . . . but I'm wedded to Aperture, I know it isn't perfect, but it does such a good 'general' job for me with the A900 and with the M8, and with a library of thousands of keyworded images . . .

    Just this guy you know

    Douglas,

    I have not really run into this problem, but probably because I neither use the camera meter nor the histogram. I follow the guidelines of DXOmark on A900 iso values which are 1/2 stop less than claimed for the entire iso range except 100 which is 1/3 over, and use an external incident light meter for most of my shots. Doing this, I get right on exposures that I rarely need to tweak in the raw converter.

    By the way, I have downloaded trial versions of DXO, Bibble 5, rawtherapee, Silkypix, Acdsee, and still subjectively prefer the output of IDC. Some of these converters may produce sharper pixels, or lower noise, but what matters most to me is the general look of an image, and for me, IDC is still unbeatable. There are of course some additional important features that I would like to see in future upgrades of IDC, such as dust removal, CA removal, arbitrary rotation and more advanced cropping.

    Re: DxO and A900 self-interest thread

    That is kind of my point. If you're getting what looks like perfectly exposed shots with the default settings in ACR, IDC, or C1, etc, then you probably are underexposing. Do me a favor and take a perfectly exposed RAW that you have, open it in C1, and click the linear curve, rather than film like curve. If your histogram isn't snug up against the right side, then you'll have an idea whether or not underexposure is an issue. Exposing for your RAW converter is very helpful, and something I hadn't considered until recently, but it makes a big difference.

    Re: DxO and A900 self-interest thread

    Just got a reply from DxO support confirming all my findings. Apparently the PC and Mac versions work differently and the manual is written for the PC version. They said they would try to get a new one out which covers both platforms.

    Cheers, Bob.

    Ok, now I see what you mean. But isn't this common to all cameras? I have done linear conversions in the past but found it too time consuming and the results were no better than those obtained with the standard conversions. Aren't linear conversions supposed to look very dark? The ones I did long ago with the original 1Ds files looked this way.

    Re: DxO and A900 self-interest thread

    Yeah, that's what I thought, too. I've come to realize that it's because Im underexposing, and the camera histogram was tricking me into believing everything was fine. Now, when I open a RAW in C1, it looks overexposed with blown highlights, but when I switch to linear, everything is fine. This essentially allows more exposure to the right, resulting in less noise. I realize that many don't mind the A900 noise, but for those that do, this improves things a lot.

    Another issue with these cameras is where they place middle grey. With the A900, exposing for the highlights at +2.5 is about right. With the 5dii, it's more like +3.5, if I remember correctly.

    so Shutter Speed 200 F16 how much can you over expose the image before you blow out the high lights? Do you base this all in C1 and Linear Response curve?

    Just curious. I have ben using DxO lately for lens correction stuff but I guess I can come out of DxO as dng then do the exposure stuff in C1?

    To be honest, I haven't used sunny 16 much since going digital, since it is an estimation, and my cameras have meters built in (or i have a meter with me.) I usually spot meter the highlights, and spot metering the A900 fully detailed highlights at around +2.5 EV is about right on (defocus the highlight before metering***) This works in Raw Therapee and C1 with a linear curve, and the histogram in RAWanalyze is right on. In lightroom, with all sliders set to zero and a linear curve, you still have to set the exposure to around -1.0 EV in the converter, because Adobe is adding some kind of boost (I believe it has to do with how they apply WB.) This is part of the reason that some say LR has such great highlight recovery....because lightroom is actually boosting your shot around a stop to begin with!

    I stay away from DxO, because, like LR, DxO adds a baseline NR even when all NR is set to off. Actually, I stay away from most converters that do a lot of special recipe stuff under the hood, because it adds too many variables. As far as DNG, Iliah Borg has gone into a lot of detail as to why it's not great, and, while I can't follow the reasons 100%, it's enough to convince me not to use it.

    Cheers, douglas


    ***defocusing the highlights makes them duller by about -.5 EV. In actuality, the green channel on the A900 blows at about +3.2 EV. Defocusing gets you to around +3 in reality, and the last .2 EV leaves room for flare and sample variation. If you want traces of detail in the highlights, rather than full detail, meter at +2 2/3 EV rather than 2.5. If you want to use the midtones to meter, spot meter +.5 EV.

    p.s. i am a nerd!

    I have just checked the DxO site and it seems that virtually all of the full frame prime and zoom Zeiss lenses and the Sony 50 F1.4, 70-200, 70-300, 70-400 lenses are now supported by the Pro Elite version. I might just give the trial version a run before buying it.

    fwiw, there is a current forum over on dpreview sony forum showing that, like ACR, DxO always does a little NR whether it is turned off or not. Also, there seems to be a problem with green casts in some cases.

    Honestly, who cares? The end result is what matters and I rate DxO top of the pile in that regard

    Re: DxO and A900 self-interest thread

    I'm the opposite. Everytime I see a DXO comparison, the detail of DxO is a bit mushy. However, I could just be seeing bad examples.

    Re: DxO and A900 self-interest thread

    I work similarly to Douglas, treating the A900 exactly like I used to do with chrome film, spot metering the highlights and overexposing by 2 1/2 stops. But mostly taking an incident light reading of the scene puts everything in place. I never get burned highlights except in contre-jour situations. Sunny 16 resulted in underexposure in most cases, even in film days. Btw, I found the camera meter to be very consistent and accurate, compared to my hand-held meter set on reflected light. Perhaps the meter overexposes slightly by just 2/10 of a stop. Nevertheless, reflected light readings often result in underexposure as they require a lot of interpretation, and they are hardly ever usable as they are, unless the subject is a flat middle grey. That's why most pros relied on incident readings in the past.

    1. I've "developped" some pictures simultaneously in C1 and in DxO starting from the same raw file and found the colors of DxO off (that is a personal thing of course). Do you have a similar experience of different colors or is it something I did wrong?

    2. I find DxO very slow, especially creating tiff files from developped raw files is imho ridiculously slow. Have you tried that?

    3. The fact that you always have to zoom to at least 75% to see various changes to me too is annoying.

    I really wanted to like this software because it has a nice workflow and lots of goodies, especially the specific lenscorrections. Now if only C1 would incorporate that in their software.

    I might still get DxO though. Like to hear your take on the points above.

    Cheers, Bob.
    An interesting review of DxO used with both Nikon and Sony A900 is in the current issue of the weekly pro magazine "The British Journal of Photography".

    It likes pretty well everything DxO does, particularly the lens corrections but could not live with it's very slow workflow. The photographer writing the review also commented on the issue of an inadequate number of lenses capable of correction, particularly none of the excellent older AF Minolta glass which I know he uses regularly.

    If only C1 did lens corrections for the A900!!

    C1 PRO does have a pretty good lens correction tool, although it isn't as advanced as DxO's, apparently.

    Edward, I should add that when I expose my highlights at +2.5 EV, I have the camera set to -1 ZONE. The ZONE jpeg settings of the camera actually affect exposure. It's almost like the A900 has highlight tone priority on all the time, and setting ZONE to -1 actually changes the metering and gets me closer to perfect exposure. You should try it

    That sounds interesting. Honestly I have not tried to understand yet what the Zone setting does so I have always left on 0 so far. Worth a try. Thanks Douglas for the tip
