Take a look at the 18th and the 19th image on this panasonic lumix fz2500 real world sample gallery. And while their ISO and EV values are not altered, their Avs and Tvs are inversely changed apiece.
Anyway, I can't figure out what priority mode s/he shot using....

  • \$\begingroup\$ I just downloaded the accompanying RAW files (Panasonics RW2 format) to look at them and the Metadata, and Lightroom 5 says it cannot convert or use these RAW files. Which is funny; because I had a Panasonic FZ200 myself, and all of the RW2 files from that work with LR. \$\endgroup\$

  • \$\begingroup\$ @smow Brand new camera probably just isn't supported yet. That's normal. \$\endgroup\$

  • \$\begingroup\$ @mattdm But, does that mean that, RAWs from FZ2000 don't support Photoshop CS5? oH! HolY crispy Crap! \$\endgroup\$

  • \$\begingroup\$ @user152435 Older versions of Adobe products don't directly support newer cameras, only the current versions of Adobe products will. It's what is known as the "Photoshop tax". You can either pay for the newest version or use the Adobe DNG converter to use the files from the newer camera with the older version of Adobe products. Do note there are some drawbacks to converting to DNG which may or may not affect the way you post process your images. \$\endgroup\$

1 Answer 1


In addition to shutter or aperture priority with fixed ISO, options include:

  • full auto or program mode
  • a program-shift mode, if the camera has one (from this camera's manual, it does not, but other brands do)
  • an ISO priority mode, if the camera has one (again, not available on this camera)
  • manual

but without asking the photographer or checking the metadata, we can't tell which. In this particular case, since the review provides full samples to download with that metadata intact, we can see (using exiftool or similar) that Shutter Priority was used.

However, if this metadata isn't available and the photographer won't tell you, there is no way to tell the difference.

  • \$\begingroup\$ Ah! but, why can ISO priority be taken? \$\endgroup\$

    \$\begingroup\$ @user152435 On this camera, it can't. On a Pentax camera, it could, though. \$\endgroup\$

  • \$\begingroup\$ On many other cameras from other manufacturers such as Nikon, Canon, Sony, etc. ISO Priority can also be selected. It's nothing unique to Pentax. \$\endgroup\$

    \$\begingroup\$ Although I think Pentax is unique in making it a separate mode; on others, it's just P but with setting ISO manually, right? \$\endgroup\$

  • \$\begingroup\$ @mattdm Nope. You can use Auto ISO with Tv, Av, and M mode as well as with P mode for many upper tier Canon EOS cameras. I'm pretty sure the upper tier Nikon cameras also offer such use of Auto ISO. You can also set the ISO in P, Tv, Av, and M mode. At least with the Canon models I'm currently using you can also set the ISO range (max and min) available within Auto ISO. \$\endgroup\$
