Sharing DPP tips

Some months ago, I asked a question Canon 550D, time to replace?I received quite a few nice suggestions. I have made my mind up to ask for a Christmas present

On the other hand, as a by-product, I learned of the DPP from Lightgreen and its DLO from AnthonyL. I tried the old 550D and I found DPP4 is really useful.

I'd like to share some limited experience here for those who, just like me, do not like editing photos.

1. First of all, as long as a photo is shot with a Canon lens, always apply DLO. Don't forget set sharpness as 0.

2. Always apply Gamma Auto, then do manual adjustment. Gamma Auto will indicate which way to go

3. Of course, adjust Histogram

The above #1 and #2 can be built into a "recipe" file, and the then, do the Ctrl+A to "Select All" and at the "Edit" tab, choose "Read and paste recipe from file ..."

There is a link that is useful Digital Photo Professional (DPP) 4 Tutorial Videos There are many DDP4 videos.

Do you have anything to share?

This has been a while of this thread. I recently did a "unscientific" test on DLO and I'd like share it with you. I hope it is useful.

When I buy a lens, I always test it at wide open with the closest distance to the subject to check its AF. The closest distance is to make sure DOF to approximate to 0

Thanks to the wide open and the closest distance, vignetting, chromatic aberration and barrel distortion are at their worst,

DLO is designed to solve them for the Canon lenses.

The test performed as follows:

1. Camera on tripod and timed in 2 seconds, to avoid shaking.

2, The Sigma 35mm f1.4 Art is used as a benchmark. Its image was produced with DPP's sharpness turned off. All parameters were set to 0.

3. Images from the two Canon lenses, EF-S 24mm f2.8 STM and EF 50mm f1.8 STM were produced with DLO off and sharpness off. The DLO00_ files.

4. DLO50_ files are those DLO was set 50.

5. DLO70_ files are those DLO was set 70.

5. DLO100_ files are those DLO was set 100.

All these images are list below:

35mm_Sigma_Art_f1.4

DLO00_24mmEFS_f2.8

DLO00_50mmEF_f1.8

DLO50_24mmEFS_f2.8

DLO50_50mmEF_F1.8

DLO70_24mmEFS_f2.8

DLO70_50mmEF_F1.8

DLO100_24mmEFS_f2.8

DLO100_50mmEF_F1.8

Some conclusions can be made below:

1. DLO is very useful.

2. The difference between DLO50 and DLO70 are not significant, but either of them improves the image quality significantly.

Any comments?
