    Exif Stats from RAW images

    in Canon EOS Mount

    Posted

    M Barbu, Its easy to port the GUI to any OS. I can probably port it quite easily to Linux, but I don't have access to other OSes.

     

    Myrddin Jones, sorry for the confusion caused by the Readme. That readme is for the perlscript that is called by the utility. I have removed it.

     

    You just need to run the Windows program "exifstats.exe" in the unzipped folder. It should bring up the GUI window as shown in the screenshot. No need to muck around in the command line. Does that help you?

    This might be a shameless plug for a free tool I just wrote that seems very

    useful to me, but I figured many others would find it useful too, so just wanted

    to disseminate the info.

    <br><br>

    If you ever wanted to know which lens you used most or which focal length,

    shutterspeed, ISO, aperture etc that you favored, here is an easy way to get it.

    Run the Exif Stats utility available <a

    href="http://www.thezeal.com/blog/?p=145">here</a> .

    Comments appreciated. Hope you find it useful.

    Photoshop CS Camera RAW question

    in Canon EOS Mount

    Posted

    Shoot only RAW. Shoot only RAW. If you are shooting jpegs, you are wasting all that your camera is capable of. Shoot only RAW. Each RAW image can lead to 1000 different possibilities. <br><br>

     

    Yes, you might want to save your images as dng as well. Hedging your bets is good. Check out how I handle image management at <a href="http://www.thezeal.com/photography/2005/02/digital-image-management.html">http://www.thezeal.com/photography/2005/02/digital-image-management.html</a><br><br>

     

    *My advice is to shoot RAW if really necessary, or as an exercise. If one wants to take great photographs, one should be spending one"s time taking photographs. Working with PS is important, but should not monopolize one's time. *<br><br>

     

    I completely disagree. Digital photography does not end with the shutter opening and closing. Its only the beginning. My opinion is to do whatever one wants to do to get what one feels at the moment into the picture.

    EF 50mm 1.4 or 2.5 macro or Sigma 50mm f2.8 ?

    in Canon EOS Mount

    I am the guy at the http://www.thezeal.com/photography site. Let me state for the record that there could be sampling error, test setup issues etc causing the 50mm 1.4 coming out second best to the the macros. Is this important to you? Well, the answer as the answer is to a great many things in this world is that "it depends". For the type of photography I do, I was unhappy with the 50mm 1.4 (or atleast my copy). Your mileage might vary. If you can, try to take a few shots using these lenses to see how it goes before you commit.

     

    However, for landscapes you should not have any problem with any of these lenses since as everyone has pointed out, you will be operating at f/8 and above.

     

    Good luck!

    Should I return my Tamron 28-75? (with comparisons)

    in Canon EOS Mount

    Posted

    I have done a similar comparison before and had concluded that the Tamron is not par to a prime lens. (In my case a 50mm 1.4 too) See sample pics and the review on my website. You might want to save the pics in your PC to see it without the browser resizing it.

     

    I use a 50mm 1.4 and a 100mm 2.8 and I am very happy with the results.

    Canon 35 MM Bodies Revisited

    in Canon EOS Mount

    Posted

    Joe, Welcome to Canon!

     

    I suggest getting atleast a Elan 7. I use the Rebel Ti and after about 1.3 years of using it, I feel frustrated sometimes when I need to do things fast. There are too many user interface quirks like "push this button while rolling this dial that makes you want to tear your hair out".

     

    This issue aside, the rebel Ti is light, fast focussing and has a bright viewfinder.

    I think you are on the right track. Metering is the single toughest thing to learn/understand/use.

     

    But as others have said, there is also nothing wrong in starting out with Av or Tv mode, letting the camera choose the exposure while you figure out stuff like depth of field, focusing, composition etc. Once you have them under your belt, graduate to manual meter control. I think it is ultimately satisfying to have a say in all aspects of the picture and get it right, rather than letting the camera choose stuff for you.

     

    Regarding film, can I also suggest that you think about shooting slide film? This is less forgiving but also gives you a better idea of how much you were "off". With print film by the time you get it back you won't know whether the problem is with the exposure or processing. I shoot 90% Fuji Velvia, yes, ISO 50. But the results are incredible.

    Canon 100 USM Macro VS Tamron 90 Di Macro

    in Canon EOS Mount

    Posted

    I originally had a Sigma 105mm macro which I sold off and then bought the Canon 100 Macro. And believe me, it was worth it. The image quality of the Canon is better than the Sigma. (The sigma was pretty good too)

     

    The difference in price is worth it for the USM that you get. The focus is fast and incredibly smooth, compared with non mfg lenses.

     

    Granted, you wouldnt use the AF when doing macro work, but I use the 100mm for 90% of my shots and fast focussing is great to work with.

     

    Image quality wise, I am sure the Tamron would be very close to the Canon. But personally I would choose the Canon over the Tamron because of no fear of future compatibility issues with any Canon body.

    Canon EF50mm 1.4 vs Tamron 28-70mm F2.8

    in Canon EOS Mount

    Posted

    Now, this might not be a valid comparison. But at one point a while

    ago I considered the tamron 28-70mm to replace my 50mm just because

    of the versatility. But here's the rub, I wanted good quality at

    large apertures too. :) Just tells me I can't have it all. For

    anyone interested, read up about an informal test I did.

     

    http://photography.thezeal.com/resources/tamron28_75vs_canon50.asp

     

    Of course, I decided not to get the Tamron. But thats just me.

    Hopefully this is useful for someone out there. Before the flames

    about the test technique etc, let me say that this is an informal

    test not meant to be the end of all tests.

    Another reason to shoot non digital

    Let me answer simply by saying I am surprised by the vehement attack made by some members about my motivations etc. I would like to clarify that the post was not about "Digital vs Film". It was simply something nice about shooting film I didnt know about. My only motivation on posting was to let other people share in the joy I felt in looking at my slides this way.

     

    Yes, I was not aware of the primitive device called the slide projector. And despite being part of photo.net for more than a year, I havent heard anyone/read anything that extolled the virtues of one. I just wanted to spread the message I discovered for myself.

     

    Not that it is relevant for the discussion, but I like digital and I know more than most on what it means to acquire images from a CCD or a CMOS sensor. I am video systems engineer by profession and I have handled integration of very large sized sensors into products. I do know that digital is the future, but my find just allowed me to savor what I currently have.

    Another reason to shoot non digital

    Posted

    I posted this here because this is the forum I inhabit the most. I

    use a Rebel Ti, 100mm macro, 50mm 1.4 and Tokina 19-35mm and shoot

    90% velvia. For a long time I was torn on the trouble I was going

    through when I shot slides. I would laboriously scan them for

    sharing and posting and it was always several hours of back breaking

    labor to finish a roll once I got it back from the lab.

     

    I had always thought of throwing my film body and going digital.

     

    Well, long story short, its all worth it. I bought a used Kodak

    Ektagraphic slide projector in Ebay for 70$. And I would say this is

    the best 70$ I ever spent other than on good lenses. Seeing your

    slides projected at 6 ft by 6 ft is simply A M A Z I N G. I fell in

    love with some of of my pictures all over again.

     

    Can shooting digital show me my pictures this way? Not today, not

    this cheap. Anyway, to anyone shooting slides and not having a slide

    projector, I say dont walk, but run to Ebay!

     

    Thank you for listening.
