Canon 5D Mark IV -- Time to Discuss!

I guess it depends on the lighting of the scene. I'm noticing it less when there are less shadows in the scene.

Maybe you need to use a conversion style with more global contrast, so the shadows are darker. If those shadows have things that you need to see clearly, then really, your ISO setting numbers don't reflect the actual exposure. If you meter a scene and you area of interest is in the shadows, the real ISO of that area can be much higher than the ISO setting. You can't cheat light by using a lower ISO than necessary, but still expose for the higher ISO; that just buys you more headroom. The exposure is what really determines the true ISO exposure index.

Having any of these will cause impacts to your higher ISO final results:

- the raw converter you use, and the conversion settings you use
- white balance settings being of will accentuate the noise
- under exposure at high ISO and amount if post
- in camera settings like ALO and NR values and picture styles, if you use DPP as your converter, or use in camera jpgs

Not all of these add noise but can make the noise there more visible. You should be able to get very good quality images at 6400, and even 12800.

Give us a sample raw and we can give you pointers.

LIGHTROOM IS SOO SLOW!!!!!!!!!!!

I hear that a lot but mine is fine. What are you running on?

Not mine

Although I have my entire catalog(s) on a SSD drive

Not mine. If I make an NR adjustment using DPP I go and make a cup of coffee to kill some time.

Speaking of computers.......

what do you guys recommend other than Apple for editing. The main thing I am after is a good screen.

In this ad, clearly the apple is inferior.

Ha! That bring back memories!

I used an expensive NEC monitor for years and my iMac and MacBook Pro were the comps that ran it. The tubes the NEC used started to die. I checked out sending the the NEC in for servicing but based on age, etc I decided it was not worth it. One day I took the NEC out of the lab and moved my iMac over as my main screen.

The NEC was more flat to replicate a print so it took a bit to get used to the glossier look of the Mac but it is OK now. I use it and my MacBook Air (when I travel) for editing with the preference being my iMac. I use i1Profiler to calibrate both. When I has the NEC I used NEC's Spectraview which is NEC propriety to calibrate it.

You want to try Lightroom with Fuji X-T2 files, I'm finding things much swifter with this 5D4 even with the larger MP count!

Should be more than sufficient. That is really strange. I was editing yesterday. Lots of files, moving edits between LR and PS, lots of adjustment brushes, grad and radial filters and I got really good performance. No lagging, etc. that I hear about a lot. The only thing I ever did in terms of tweaking for performance was increase the camera RAW cache and make sure the use graphics card tab was enabled. I'm running an iMac 5K with 32 gigs of RAM. My catalog resides on my internal drive and my photos are on an external RAID array connected via Thunderbolt.

What size is your camera RAW cache? If you have a lot of disk space increase it. I've read some users getting big performance increases by setting it to between 50 and 70 gigs.

Maybe we have different ideas of slow?

Likewise, ... still slow,

4 Core 4Ghz Intel, 32GB RAM, and SSD, still slow! (compared to other RAW converters I use)
Back when I had my AMD Opteron set up, LR was still the slowest, and RawShooter Professional (R.I.P.) was lightning fast by comparison. Likewise Bibble (also R.I.P.) and C1.

I don't think it is strange, it seems to be the norm based on a combination of different versions, (going back to 1) different installs (at least half a dozen by now) and all the similar reports I have read over the years.

My favorite part was when they added GPU acceleration and turning it on made it slower
