Advertisement Posted June 19, 2007 Posted June 19, 2007 Hi Photoskeptic, Take a look here Old shrimp boat. I'm sure you'll find what you were looking for!
timothy Posted July 18, 2007 Share #2 Posted July 18, 2007 So, the first picture shot on film appears to be much more three dimensional than the second shot on the M8. Why is that? Is it because of the tone curve? Because the midtones appear much brighter? Because of increased microcontrast? Or is there something hidden, esoteric, mystical going on here?

timothy Posted July 18, 2007 Share #3 Posted July 18, 2007 To eliminate the field of view as a reason, I have cropped the first picture and downsampled the second to match more closely. Link to post Share on other sites More sharing options...
Photoskeptic Posted July 19, 2007 Author Share #4 Posted July 19, 2007 Well, Timothy, you got me to re-look at my own images with a better eye! First of all, I notice the blacks are better in the M8 version. I find that surprising. The marsh grass (spartina) is sharper in the film image. Efke 25 is probably the slowest film available today and I've gotten some terrific shots with it. I give it credit for the more 3-D look. Then again, with both re-sized for the web who knows? And I apologize for not posting these at the same size, thanks for doing that:) As for the midtones, I suppose I could play with both using Curves and the results could be anything I wanted. However, once each shot was introduced to PS I worked each image to produce the best outcome. Now that I have CS3 I would probably do each one a tad differently with the M8 image getting the better processing than the previous effort. Link to post Share on other sites More sharing options...
timothy Posted July 24, 2007 Share #5 Posted July 24, 2007 I notice the blacks are better in the M8 version. On the contrary, I noticed the black are "better" in the Efke 25 version. Fortunately, the blacks in the M8 version were easily "enhanced" in Photoshop (Duplicate Layer then Filter > Sharpen > Unsharp Mask; Amount: 20; Radius: 40; then Blending Mode: Darken; Opacity: 80). Overall, that improves the M8 version somewhat, but it still looks like a gloomy day rather than a sunny one; there is still very little contrast in the mid-tones; and there is still almost no tonal variation in the water. Look at it! It's just an empty gray, eh? Link to post Share on other sites More sharing options...
timothy Posted July 24, 2007 Share #6 Posted July 24, 2007 There is still very little contrast in the mid-tones. The contrast in the mid-tones can be increased, among other ways, with use of the High Pass filter. Link to post Share on other sites More sharing options...
timothy Posted July 24, 2007 Share #7 Posted July 24, 2007 Advertisement (gone after registration) There is still almost no tonal variation in the water. Look at it! It's just an empty gray, eh? With a lower but not infinitesimal radius, some tonal variation can be brought out using the High Pass filter once again. Link to post Share on other sites More sharing options...
timothy Posted July 24, 2007 Share #8 Posted July 24, 2007 With selective application of Curves, the mid-tones can be made less muddy without affecting the brightest highlights. Link to post Share on other sites More sharing options...
timothy Posted July 24, 2007 Share #9 Posted July 24, 2007 Something is still missing. It still doesn't look convincing. Compare the Efke 25, the revised M8 version, and the original M8 version. Link to post Share on other sites More sharing options...
fotohuis Posted July 24, 2007 Share #10 Posted July 24, 2007 The only conclusion I got is that a CCD can not registrate what a classical B&W film can. Something is done in the conversion to the grey tones in each digital camera and it can never be compared with a real B&W film. It not only happens with this M8 but also with a 5D or whatever. However Efke 25 seems to be rather "crappy" compared with a more modern slow speed B&W film: Slow speed film comparison So on both sides reasons for improvement Link to post Share on other sites More sharing options...
Photoskeptic Posted July 24, 2007 Author Share #11 Posted July 24, 2007 Robert, the Efke image was shot with my last roll and the expiration date was six months ago! Even so, I do find for a 25 speed film, the Efke still has some grain. I bought this Efke when it was the only 25 rated film to be found. I haven't tried any others yet, but I will. Thanks to all for their replies and Timothy for his work on this image. Link to post Share on other sites More sharing options...
fotohuis Posted July 24, 2007 Share #12 Posted July 24, 2007 For an iso 25 film it doesn't matter if it is a few years over it's expiration date. I only want to emphasize that slow speed B&W film is increadible good comparing with a digital camera. Also with Efke (25) you can minimize grain, the same you can do with a Rollei PAN 25 film, which is more sturdy, slightly finer grain, flat, PET layer and non-curling layer. It's in fact an improved OrWo NP15 film. For neglectible grain you can develop in CG512/Rollei L.S. developer, which is an ultra fine grain developer and then I can tell you of my own experience even with a 40x50cm print you will see no noticeble grain. All these slow speed B&W film have a resolution (ln/mm) just over the max. resolution of a Leica Summicron, around 200-220 ln/mm and a Summicron is one of the best lenses available. But your photo is OK, even with the M8, it was just remarkable you put the same picture from your M3 and M8 under simmilar conditions for direct comparision.
