I believe Gerry means that with the contrast and sharpness cranked up, he can see better whether or not the AF has done its job to his liking. I shoot raw, and crank up the sharpening when I am in using the back LCD to determine focus hits/misses. It works. But you are right, it has no effect of AF performance. It just allows you to better see the AF results.

Exactly

Yep, I do the same thing Gerry S(7,1,1,0).:-)

To everyone who's saying "Contrast doesn't affect AF":

He's not saying that it does. He's just saying that it optimizes the on-camera preview so that he can check at 100% magnification on the LCD TO SEE IF THE FOCUS IS PERFECT and if not then reshoot. The RAW file remains unaffected.

That's right

this is a good idea that i had not considered. It is especially nice as my eye sight is starting to fade with age.

do you need to shoot RAW + JPG or is the picture style applied to the small preview file used by the camera even if shooting RAW only?

Age is but one factor :oops: I shoot RAW only

rrblint wrote in post #17397799 (external link)
No need to shoot RAW+JPEG. RAW-only is fine as the LCD preview uses the camera settings for display, even though the actual RAW file remains unaffected.

Exactly!

The software I use (Shotwell for database) will use the JPEG information to create a JPG file whether I like it or not, for detailed viewing on the PC. I use these JPEGs to decide which RAW files to work with, but that's just my workflow. I could just as easily bypass Shotwell when importing the photos and use Darktable as the database (very similar to LR) but I like the quick access Shotwell gives me to over 15000 photos I have, complete with tags.

When you take the files into Lightroom, what are you typically doing? I'm curious as to what changes most of you are makin to the file.

It varies from file to file Frodge. Unfortunately there is no "One Size Fits All" workflow for Lightroom or any other processing software.:-)

yes exactly ^

this is the order I work in:

Cull bad shots and do some basic organizing
Set set color temp and tint (aka white balance)
Set exposure, contrast, saturation, recover highlights and shadows. These settings are all tied together, none is really first or last.
Clarity/Structure
Crop
Sharpen / Noise Reduction

All of the above are virtually requirements, but it is dependent on the event/shoot. Sometimes steps are skipped.

As I am processing the images i refine my organization with stars or color codes. i always do "correct color" first and then create any variations from the originals.

I usually start by culling rejects. Then, if necessary group shots that need similar gross adjustments like WB and Exposure.

After that I work my way down the DEVELOP panel.

BASIC TAB
I generally decrease contrast a bit. For most well exposed shots I don't touch the (Highlights, Shadows, Blacks, Whites) sliders.

My defaults are as follows (where I start):
Clarity: +10
Vibrance: +15
Saturation: +5

Skip HSL/Color/B&W tab.
DETAIL TAB
Sharpening: Amount 35 (tweak with NR), Radius 0.5, Detail default, masking 50

NR: Luminance is ISO based, higher ISO needs more. (Tweak with sharpening). I don't use the Detail and Contrast sliders. They just confuse my interplay between Sharpening and NR.

Color: just enough to almost kill color noise, also ISO dependent.

Lens Corrections. I check ENABLE PROFILE CORRECTIONS.

That sounds like a lot, but it takes me way less than a minute to do a group of photos. I don't spend a lot of time agonizing over perfect. Good enough really is.

If I blow the shot in camera, or lighting is funky, I can fix a lot of crappy work in the HSL/Color/B&W tab. Sometimes I want manual vignetting and distortion corrections. Lens Corrections tab/Manual gives me all that. These last few things are generally attempts to fix something I did wrong. As I improve, I get fewer shots needing this stuff.

LR certainly has a learning curve. The reward for your invest is shots tweaked the way YOU want them, not the way some Canon Engineer thought you'd like them. Occasionally, I check my work against SOOC Picture Style default JPGs. I would guess that 98% of the time, I like what I produce more. Once you get used to it, it takes no time at all. The hardest part for me is still culling rejects.

Where do you suggest a good place to start is for homemade JPEG sooc?


MakisM1 wrote in post #17397006 (external link)
You can copy a Standard to the custom profile and then play with sharpness, contrast, skin color. Canon as quite a few ready made ones, and an editor to make your own. Haven't gone that far myself.

I had a 450D (Xsi) and the one consistent thing I noticed was soft focus on outer points, vs the center, and if an image was underexposed it would be much softer than the correctly exposed shot.


Godox/Flashpoint r2 system, plus some canon stuff.

Hi Folks,

I recently acquired an EOS 450D 3nd Hand, in good condition.
I Picked it up cheaply, and managed to get a standard Canon 18-55 Lens for it and i thought they'd
be similar in image quality unless you were doing serious photography but wow.

The difference between the 2 camera's is huge.
Her's is just so crisp, and even at high magnification there is a huge amount of sharp detail,
i took a picture of her in my camera when she was curling the ends of her hair with one of those GHD things from 6 feet away with my Canon, when i zoomed just once or twice, i could see no definition around any edges, i could BARELY see GHD written in the big letters and the gold on black writing of the made in x-country was just a small fuzzy gold blur.

None of the edges are defined, everything seems VERY soft, and even sharpening slightly in an editing program just doesn't give me what i need.
I thought maybe with a high quality camera like this that i'd notice some softening and blurring on distant shots etc, but even in close shots, medium shots etc it's very streange. I've got a 16mp camera on my phone that can almost match the quality im getting from the 450D... am i doing somethin wrong? i tried manual and auto, tried many different shots. And the Nikon is just wiping the floor with it, i'd say there's approx 3x as much detail in each shot. Here's an example of my Canon's shots im talking about, any suggestions? Here's 3 examples.
[A]

I agree with some of the other comments, it's difficult to see your comparisons and methodology but when I had my XSi /450D it produced sharp pics


XSi / 450D with Tamron 90 and 100-400

By "zooming in" do you mean on the camera lcd screen on at home on your computer screen? The 450D, aka Xsi is an old camera with a low resolution lcd screen that cannot show sharp details on the back of the camera. Try viewing your pics on a computer screen.

I think the OP has left the scene
perhaps contemplating her "image quality" compared to the old XSi

Agreed. There must be some basic personality differences among photographers. My first thought when I don't get what I want/expect is, "What did I do wrong?" Seems like some folks go to equipment failure first. The camera is a stupid box that does what it is told. If it isn't performing well, check the instructions you gave it.
