That looks like a raw in-camera processing issue. This feels like a computational issue based on the varying band sizes, whether in-camera or via raw conversion. Here is an equalized view.

I think an isolated image can be disregarded as just a hiccup.

Also, it may be worth arguing the point that we should be properly exposing in the first place... :p

Well of course. I'm actually pretty sure I fired that shot off accidently and was going to delete it but said eh... it's underexposed lets see what it can do and saw that. yuck.

Again haven't seen any other case of this and I've pushed some real world shots +3 without hiccup. This particular image had this banding issue at +1 with shadows at 100.

Switched my Sigma 85 Art preorder to Adorama to get the free dock.

Can't wait to see what this "A design that prioritizes optical performance—without compromise" is suppose to be all about. I know it will be a heavy lens but I will try it out none the less. Will be interesting to see what it can do with the 5D4

Perharps a good way will be to process this raw with CAPTURE ONE ... :rolleyes:

The latest update to Adobe CC will now support Canon 5D MKIV RAW files. .....feel free to spend your hard earned $$$$ because you can now develop in raw format.............#bo​om....#gamechanged.

Does Canon typically have any rebates soon after a new body comes out or sales given the time of the year?

ok i logged into my computer and exported a before/after and the settings. Again I haven't found any other image that has done this so maybe it's some kind of fluke with adobe reading the raw of some sort?

This was ISO 100

This looks very similar to what my 80D does with severely underexposed images with certain scenes (pretty much only in extreme experimental shots, never happened in real world scenarios). It has been discussed in one of the 80D threads in detail and more test photos.

Yea, I saw something similar in rare cases with the 80D; oddly it manifested itself on a shot of a white wall (you could see purple/green stripes).

We should be careful when talking about "banding", because that's generally been used to describe the column type noise seen on older Canon sensors, whereas this goes across an image.

IRC John was talking about analysing the usually invisible portion of the raw (i.e. the borders), and if those issues were present then it should be feasible for a raw processor to correct the problem in the visible portion.

George Zip wrote in post #18134061 (external link)
I don't really understand how the relationship between sensor and lens works in regards to detail, but the Lens is producing better images(IMO) on the 5D4 than my 5D2 and 7DII.

Pixel size vs sensor size vs print size basically. A lens will have an ability to resolve a certain amount of optical detail (sometimes recorded as line pairs per mm). If the resolution of the lens outresolves the resolution of the sensor, then it comes down to the area of sensor you use and how big you view it (i.e. print size). Taking a smaller crop (or printing bigger) will result in a higher magnification. In that scenario, the pixel resolution of the digital image would be the thing that lets you down first.

If you had a really high res sensor (that significantly outresolved the lens) then your magnification ratio for a print would be limited by the lens resolution.

The modern Canon glass (especially the L series models) have been really good - and you will see more detail with a higher resolution sensor.

One good way of gauging this is to look at DXOMark's perceptual MP rating for lenses. If a lens gives a good result on a crop sensor it's likely it would be able to give good detail even on a high MP full frame sensor.

One useful example was some data I saw on the Tamron 150-600; at the long end (and wide open) it could only resolve (IRC) something like 8MP on a crop sensor. As such, if you used it on a 5D3 and took an APS-C crop you wouldn't be any worse off - because the FF crop would be around 8MP, but the higher resolution uncropped APS-C image would only contain about 8MP "worth" of perceptual data.

Or to put it another way: more MP is always good if your lens can resolve that much detail.


Camera, some lenses, too little time, too little talent

Updated my lightroom this morning and offloaded my cards. Good thing too because my son has baseball tonight, tomorrow and thursday so I suspect around another 1k shots or so.

just recieved my new tamron 90mm f2.8 macro lens :)


Anyone using this lens on a 5d4?

From what im reading from the posts in England, its mind boggling how good the raw files are. So anxious to see some of your shots after you get them out of LR

The new sensor has changed the way I shoot. I shoot for the highlights because I can pull shadows and darks w/o being penalized. I have avoided far right with previous models and im shooting right in the middle so Highlights are on the $$$.

That's great news, and I assume that does mean the standalone 6.7 will have it. Of course, actually finding it is nigh on impossible because Adobe seem to do everything possible to disguise the fact that there is a standalone LR. The newest version their downloads page contains is 5.7.1!

When I next fire up my machine with LR 6 (hopefully tonight) I assume it'll pick up the update.

EDIT: Maybe here (it lists an update link for 6.7, but I haven't tried it): https://helpx.adobe.co​m …/lightroom-downloads.html (external link)

When I opened LR this morning the update pop-up appeared and I have the stand-alone version (in the UK). I'm sure you will get it as well. BTW I just sent in my 5D3 to Wex as part exchange so expect the new camera next week. Can't wait!

This is a new learning curve for me. I'm use to ETTR to protect the shadows and just let some highlights blow out. I definately shot differently at the zoo this past weekend. So far alot so good. I'm at work but can export a few shots from the RAW in lightroom and post. Kind of hard to do through teamviewer but it's workable.

I saw an Adobe Camera Raw update when I updated LR this morning...could that be it?? (Although I haven't opened ACR for a whie so it may be an old update!)

I think that one is an older update. The only one I got this morning was LR.

I work with LR 5 and elements 11. I assume I will have to upgrade to the latest version and then pay the monthly subscription fee if I buy the mark 4 ?

Or DPP, considering Canon wrote it for their own raw files... ;)

Especially when you think you have a raw issue...
