  • Replied in Another tip
    A better tip - unless you are an expert, shoot in manual mode never. Until you become expert you can (but don't need to) shoot in manual as a learning exercise. But buying a camera that includes a ...
  • It is Adobe Camera Raw (ACR), the raw conversion module in Photoshop. Lightroom's Develop nodule is virtually the same. The red shows highlight clipping, the blue shows shadow clipping. Look at the ...
  • Replied in sharper image?
    What do you want sharper? The EXIF says you used Portrait mode (for closeup photos with the background out of focus) so, as you'd expect, that's more or less what you've got. The background isn't ...
  • Replied in Polariser fail
    Mostly a matter of economy. My typing is pretty slow, and I try to keep things brief and (approximately) right on occasions when I can't rally cope with the full explanation. Thanks for doing the ...
  • This isn't stacking, which is merging several exposures into a single still image. What you need to do is convert the pictures into a .gif file using software such as this (I'm sure there are ...
  • Replied in Sensor Size
    Not really. This diagram shows some of the sizes that have been used but they aren't the only sizes used by some makers, nor are they all the sizes those makers use. There aren't really very many ...
  • This first one shows the classic symptoms of wide dynamic range. Some of the clouds and bright parts of the car have lost all detail - "clipped to white" - and some of the shadows are "clipped to ...
  • Some of your shots look quite decent. However, asking people to plough through dozens of shots, then having to identify one (or more) of them for critique is inconsiderate. If you want comments on ...
  • Which one? Q7, K-70, K-1, 645Z? The Q7 is the only one that fits the OP's requirement for light weight. All my cameras (except my phone) are Pentax; but I don't think anything Pentax makes fits the ...
  • I agree with that in principle, except the "not that difficult" part is by no means always true. Which sliders? There's a lot of skill needed to decide which slide(s) to use. And there's no easy ...
  • True; but this raises another point about TCs in general. By magnifying the whole image a TC magnifies everything the lens does. This includes the thickness of the finest line the lens can resolve, ...
  • The number of megapixels is the least important of all the factors in camera design. There isn't a camera on sale today that doesn't have plenty of MP. Any camera you buy will give good pictures if ...
  • Replied in Polariser fail
    Joe is half right. Polarisation works most strongly at 90 degrees to the direction of the source, so for light reflected from foliage, rocks etc with the sun as source what Joe says is true. Howeve ...
  • Submitting photographs is unfair to painters, who don't have the skill of taking photographs. Because part of the process is taking the photograph in the first place: being there, making the ...
  • With a Canon camera why don't you start with DPP? It's not just a free trial but completely free and designed to work with your camera. Wrong, except at the most trivial level. There are huge ...
  • Replied in A bit more
    The autofocus "points" on your camera are actually crosses (middle of frame) or lines. In both cases they are quite a lot bigger than the red dot that lights up in the viewfinder, so you can't ...
  • The camera is fine. The lens is OK for what it is but fits your description of "nothing high-end". You've hit one of photography's many compromises - top quality doesn't come cheap. These charts ...
  • It's a good camera at a good price but you'd need a lens too. As Samsung has pulled out of the camera market the options for second-hand lenses are likely to be limited, so unless you see a ...
  • Bokeh is the quality of the out-of-focus blur in a picture. It depends on the lens, not the camera. But ... ... whereas bokeh describes the quality of the out-of-focus blur in a picture, the amount ...
  • Replied in Sensor Size
    There's a diagram at the top of this link that shows some common sizes. There's a table at the bottom that lists a lot more. https://en.wikipedia.org/wiki/Image_sensor_format In between there's a ...
