Tom Axford's recent activity

  • I acquired this lens nearly two months ago as I was attracted primarily by the small size. I previously had no zoom that covered that range as I didn't want a large lens to carry around in ...
  • Replied in GIMP
    I use Lightroom (not free) for developing raw files to jpegs, and then GIMP (free) for more sophisticated processing (instead of Photoshop, which is the common follow-on to LR). GIMP lacks some of ...
  • A photocopy or facsimile is an exact copy (in the former case, done by photographic means) of a document (of any type). However, I have a suspicion that this answer is too simple and isn't quite ...
  • Your depth of field at 6 ft is about 8 inches. So it's impossible to get everything in focus with this subject. I suggest you stop down to f/8 at least. Even so, you're not going to get everything ...
  • Seen enough worms yet?
  • Where I live in the English Midlands, we get a sprinkling of foggy days during the autumn and winter particularly.  They are a favourite time of mine for photography because of the atmosphere ...
  • This is an argument that has raged in many threads and never seems to end. Two months ago, I did a straw poll  to see what the balance of opinion was on essentially this question. Sadly (to me), a ...
  • According to your definition of manual modes, I use them virtually all the time. However, personally, I would define manual mode as meaning M mode with fixed ISO. Everything else (PAS and M with ...
  • Replied in Dynamic range
    Yes, except that the larger sensor will probably give a greater dynamic range. However, even fairly small sensors give quite adequate dynamic range at base ISO, unless you want to shoot in raw and ...
  • Replied in Cut & Paste
    It works fine for me. Probably a problem with your browser.
  • http://toothwalker.org/optics/dof.html is a rather technical tutorial on depth of field that also explains background blur (scroll down to the section with that heading).
  • 100mm at 20ft gives about the same DoF as 50mm at 10ft (and same f-number), but it gives about twice as much background blur (for a background at or near infinity). Try it out yourself. It is easy ...
  • If you google "photograph a painting", you will find that there is a plethora of advice available. It's probably worth quickly scanning through some of the advice to see what suits you. Like ...
  • Perspective distortion occurs only with three dimensional subjects. If you are photographing a flat sheet of paper or canvas, there is absolutely no difference in the images obtained with 50mm and ...
  • As you have suggested, the lens is more important than the camera. To get the best quality in copying, I would go for a macro lens as they often give better image quality right across the frame ...
  • There may be no advantage to you,  but there is a great deal of benefit to the lens manufacturers who make much more profit on the large, expensive, 'premium' lenses. I think photographers often ...
  • If you are unfortunate in having a bit of tremor in your hands which makes it very difficult to hold the camera steady, then using a flash is probably the best option as you suggest. The other ...
  • Export the image. In the dialog box that appears, you can select "Resize" and specify the size you want.
  • Replied in Photodo
    The Photodo website contains some MTF data on a number of legacy lenses. The site published some very detailed independent MTF measurements on many lenses back around the year 2000 and earlier. ...
  • Replied in Both
    I like both wide and long for landscapes - it's nice to have both available. I particularly like the Lumix 12-32mm f/3.5-5.6 and the 35-100mm f/4-5.6, both of which are remarkably small for what ...
