"LR 5 Lens Correction"



We were discussing workflow in the Develop Module in LR5. A friend says he does the Lens Correction, checking the Enable Profile Corrections box, last. He claims that doing it first causes his computer to slow down when using the sliders in the Basic, Tone Curve and other Modules. I do the Enable Profile Corrections as a preset when importing and have seen no slow down when continuing the work flow.
Has anyone experienced this?

I cannot say I have noticed any slow downs with the lens correction turned on, but I also have a rather beefy computer.

Back in the day when I had much slower computers and a graphics card that lacked a GPU - I had to be careful of the order of processing. There was no lens correction feature then, but sharpening and particularly noise reduction would really slow down all of the other adjustments. I don't see it anymore with a reasonably fast PC and good graphics card.

> "I had to be careful of the order of processing ... sharpening and particularly noise reduction would really slow down all of the other adjustments."

If I may offer a suggestion, it's not the order of adjustments that causes sharpening/noise reduction to slow down development. Even if you don't add any sharpening/de-noising, LR still uses some default settings. Key here is deactivating the entire sharpening/de-noising panel while you work with the other adjustments. When you are done, you can re-activate the sharpening/de-noising panel. It's the half-black, half-white rectangle, like a slider that's either in the up or down position.

If you want to do sharpening/de-noising first, for example to check if a photo is worth working on, you can do so, then deactivate the panel until you complete all the other adjustments, and then re-activate the sharpening panel.

Regards, Antero

I enable the lens profile corrections as part of my camera defaults and don't have problems on either of my computers, both of which are about four years old.

I too enable the lens profile corrections as part of my image import defaults along with remove chromatic aberration under lens correction. I have seen no slow downs on a 3-4 year old box.

Ditto. Can't remember the processor speed just offhand--it's nothing spectacular-- but my PC has 8 GB RAM, not a super-computer for sure.

Thank you everyone for your replies.
The person in question has the same iMac, 27" screen, that I have. I think it might be a RAM issue, not sure how much is installed. I have 16 GB, the max, in mine.

It may depend on the type of corrections you're applying and how many you have applied. Some are more resource intensive than others. Adobe does suggest an order of operations to optimize performance.

Order of Develop operations
The best order of Develop operations to increase performance is as follows:

1 Spot healing.
2 Geometry corrections, such as Lens Correction profiles and Manual corrections, including keystone corrections using the Vertical slider.
3 Global non-detail corrections, such as Exposure and White Balance. These corrections can also be done first if desired.
4 Local corrections, such as Gradient Filter and Adjustment Brush strokes.
5 Detail corrections, such as Noise Reduction and Sharpening.

Note: Performing spot healing first improves the accuracy of the spot healing, and ensures the boundaries of the healed areas match the spot location.
