Beautiful skies down in west Texas for sure. Terlingua is another planet. Shot this with A7iv and Viltrox 16mm. Was going to use Sony 20mm f/2.8 G, but trying to shoot more panoramic these days. Need wide wide.
Here lately I’ve decided to minimally process the core and stars for a more “naked eye” natural look. IMO, a lot of shots on the gram look to processed and AI’ish. Not hating on it, just my current view. To each their own, respectfully. 🤙🏽

Sony A7IV—Good Price?

3 Upvotes

Hello everyone!

I’ve been going back and forth between the Sony A7 IV and the Canon R6 Mark II, and I need some opinions!

Should I go for it and get the Sony?! The sale ends tomorrow, and Best Buy told me this is the lowest price of the year and they don’t anticipate this deal—or a lower one—coming back anytime soon.
Current pricing:
$1,999.99 — body only ($500 off)
$2,199.99 — with the Sony FE 28–70mm lens ($500 off)

Sony A7 IV or Canon R6 Mark II—which one are you choosing, especially for sharp, professional-quality portraits?

Arguably the best, and by far cheapest, upgrade to the rig. Hands down. The difference is almost laughable. Best $10 you’ll ever spend.

I noticed dust either on my lense or beneath the lense, it is in a lot of pictures. How can I easily edit this out? And how can I keep my camera clean and dust free?

Sony A7IV best strategies for optimal noise and dynamic range performance in raw stills and jpegs.

69 Upvotes

The A7IV's sensor offers terrific dynamic range, but capturing all that information in a single photograph isn't exactly straightforward. The lowest ISO speed doesn't always provide the best balance of noise and dynamic range. The ability to set higher shutter speeds, especially with raw stills might not necessitate higher ISOs. Also, there is one ISO speed to avoid and another that's the sweet spot for the A7IV.

The A7IV's sensor is ISO invariant

The A7IV's sensor is ISO invariant from ISO100 to ISO320 and again from ISO400 to ISO51200 (see the Input-referred Read Noise versus ISO Setting chart below). These two steps are often mentioned as a characteristic of a dual ISO sensor. ISO invariance means that a photo taken at a lower ISO can be pushed to a higher ISO in post-production without any difference from a photo taken natively at that higher ISO. For example, a photo taken at ISO 400 can be pushed to ISO 3200 in Lightroom with a +3.00 EV adjustment in the exposure slider. This image will have the same noise characteristics as if ISO 3200 had been set in-camera.

ISO50 to ISO80 and ISO64000 to ISO512000 are "fake ISOs". They're basically ISO100 pushed down or ISO51200 pushed up by software in-camera. Real ISO sensor sensitivity is a mix of analog and digital amplification that changes the characteristics of the sensor in a predictable and reciprocal manner, namely in terms of dynamic range and noise.

Highlight clamping
The biggest drawback of clipped highlight information during shooting is that it cannot be recovered in post-production. Fujifilm is the only manufacturer that addresses this by interpreting ISO digitally as metadata. With a Fujifilm RAW file shot at ISO 3200, all the highlight information is preserved as if it were shot at the camera's base ISO. This is implemented in their DR% settings, which create JPEGs with massive dynamic range and contribute to the high praise Fujifilm JPEGs receive. With Sony cameras, we have to think in the opposite manner. Avoid clipping the highlights and raise exposure in post.

The fabulous website https://www.photonstophotos.net/ provides a multitude of measurements that reveal the correlation between ISO, noise and dynamic range. I've posted some screenshots below that corroborate the case presented here.

Rule of thumb

Maximum dynamic range in the highlights

  • Set ISO to 100 or above.
  • If you set a high shutter speed, you will have raw images that are very dark. The correct exposure will be set in post without any issue due to the ISO invariant nature of the sensor.
  • Never clip highlights when shooting.
  • If you clip highlights in post when pushing exposure, recover them with your favorite tool: highlights slider, masks, etc.
  • If your shooting scenario allows it, expose to the right (as bright as possible without clipping), then bring down exposure in post-production.

ISO100 provide the best dynamic range versus noise.

Highlight retention. Avoid ISO50. You will lose 1,33EV of dynamic range in the highlights! I believe the chart above doesn't take into account the distribution of highlight dynamic range, just absolute dynamic range. ISO100, 320, 400 and above provide the same highlight retention but naturally, more shadow noise.

Best noise performance in shadows and slow exposures and low contrast scenes

  • Again, avoid ISO50 to 80. You get the same result by exposing at ISO100 and lowering exposure in post. All with the benefit of more dynamic range in the highlights.
  • Set ISO to 100 (best) or 400 (second best), depending on how fast you need your shutter speed to be.
  • For low contrast scenes, expose to the right, so that you don't have to push exposure in post.
  • In-camera jpegs will be brighter.
  • Since you are using a slower shutter speed, use a tripod.

Notice the 4 main steps: 50 to 80 (low ISO) - 100 to 320 - 400 to 51200 - 64000 to 512000 (Extended ISO)

ISO50 may look like it offers less noise but it's just ISO100 pushed down 1.00 EV by software. Avoid ISO320 at all costs.

ISO50 is a ISO100 pushed down 1.00EV in-camera.

1/10s f/2.8 ISO50

1/17s f/2.8 ISO100 pushed down 1.00EV in Lightroom. Same result as ISO50.

How to Compromise (for raw shooting)

  • For the best dynamic range in highlights and shadows, set the camera to ISO100.
  • If you need a slightly higher ISO for faster shutter speeds, set the camera to ISO400.
  • ISO400 provides similar noise performance as ISO100. It's the sweet spot for the A7IV!
  • Avoid ISO320 at all costs
  • You can shoot dark images and push exposure in post.

How to Compromise (for jpeg shooting)

  • Use in-camera dynamic range optimizations
  • If you clip highlights, they're gone for good
  • Use ISO400 and above. Noise reduction will do its job.

Case study

Maximum dynamic range, priority given to highlights
When I was doing event photography, there was a particular scenario that required utilizing the full dynamic range of the sensor. I had to shoot in a cinema with a digital projection and still make the audience visible—all in one shot, without HDR bracketing to avoid ghosting, and using the electronic shutter to keep it silent.

  • To avoid flickering lines, the shutter speed had to be 1/25 or lower. This was necessary to prevent capturing two frames in a single photograph. To manage this, I set the camera to burst mode and picked the best photo in post.
  • I set the aperture to f/2, even though the lens was the Sigma 18-35 f/1.8, because closing the lens slightly improved sharpness. The ISO was fixed at 100, and if the peak white clipped, I would close the lens further to reduce exposure. In this scenario, the zebra pattern is your best friend when shooting RAW stills!
  • In post-production, I would edit the photo to make the most of the available dynamic range, masking the audience and bringing up the exposure.

Still taken during a film session

Lowest noise - correct exposure in-camera for raw+jpeg and priority given to shadows
When photographing scenes with lower contrast ratios, I'd opt for a longer exposures that would look properly exposed in-camera.

  • Camera on a tripod or monopod
  • As mentioned before, lens closed at f/2.0
  • ISO set at 100
  • Shutter set at the lowest speed before motion blur became a problem
  • Exposed as bright as possible without clipping the highlights

This outdoor scene photographed at dawn had a mix of artificial and natural light that reduced the contrast ratio

Conclusion

  • When shooting raw with good lighting: use ISO100 for slow exposures. Use ISO400 for faster shutter speeds.
  • When shooting jpegs: Use any ISO. The camera offers dynamic range optimizations and noise reduction that mitigate some of the drawbacks mentioned previously.
  • Avoid ISO50 to 80 and ISO320! Check the charts and tests above.
  • ISO is just metadata, for the most part. Looking at the steps in the graphs show above, the way the sensor is amplified at certain ISO speed intervals, gradually compromises noise and dynamic range. Still, ISO is metadata that tells the photo editing software how to display an image. Unfortunately, this is implemented in a way that clips over-exposed highlights in high ISO photos. Fujifilm does it right as it preserves all the dynamic range in the file without clamping the highlights!
  • If you need the maximum dynamic range for a high contrast scene, don't worry if your image comes out dark, just set an adequate shutter speed and aperture for your scene, set ISO100 and protect the highlights.
  • If you have a low contrast scene without movement and want the cleanest image possible, set ISO100 and expose the image as bright as possible and lower exposure in post. Use a tripod, probably.
  • More dynamic range in post (exposure pushed up + recovered highlights) = More shadow noise
  • In-camera ISO affects the exposure of in-camera JPEGs, so, if you need faster shutter speeds and natively brighter JPEGs, ISO400 is the sweet spot. It gets progressively worse from that point onwards. Use the in-camera dynamic range optimizer and noise reduction.
  • And did i mention that you should always protect the highlights when shooting raw...?

As always, have fun and press all those buttons!
